Why Less Megapixels Can Sometimes Be More

Why Less Megapixels Can Sometimes Be More

The number of things I have learned, unlearned, and relearned all over again along the road from hobbyist to professional photographer would require something of a short novella to recount in their entirety. So today, I want to share just one of them.

Before I start, I’ll mention the usual disclaimer that this discussion is based on my own experience, my own style of shooting, my own clients, and my own peculiar set of tastes. So, since no two photographers are the same, no single piece of advice can ever be one size fits all. That, by the way, is also one of the things I’ve learned along the way. It’s not what I’ll be discussing today. But, it still bears repeating. As for what I actually do want to talk about today, let’s get right to what I've learned.

We are photographers. We love cameras. It is highly likely that our infatuation with the art form began sometime around the first time we held one of those strange combinations of metal and glass in our hand and heard that distinctive sound of the shutter as it went click. As we journeyed towards our new passion in earnest, we obsessed over every new camera body that arrived in the marketplace, each more beautiful than the one before. We committed manufacturers' spec sheets to memory. We’ve probably gotten into more than one unnecessarily heated argument over why our chosen camera brand is better than that other one.

Part of that eternal debate very often centers around the ever increasing number of megapixels in your camera versus the other guy's or gal’s camera. One of you may argue that 100 megapixels is far too many. Another may argue that 20 megapixels is too little. It’s quite possible that a somewhat sophomoric quip about someone overcompensating might even be thrown in there at some point.

I get it. I’m in the same boat as everyone else. I have cameras ranging from 24 MP to 102 MP. I’ve spent hours in front of a computer pouring over the “image quality” of each camera, going over the files with a fine-toothed comb to parse the differences. And there are differences. But, often along the way, I also tend to conveniently forget that I began my career on the back of a 10 MP camera. It was enough to get me published in major international magazines and get the ball rolling on a portfolio. Yet today, the idea of buying a 10 MP camera likely wouldn’t even occur to me.

To be sure, the images I take today with higher-megapixel cameras are far better than the ones I took with my old Nikon D200. But I hasten to say that the improvement is more the result of me being a better photographer now than I was 15 years ago, rather than just an upgraded sensor.

Case in point, about a year ago, I bought a 102-megapixel Fuji GFX 100 after a career using Nikon DSLRs, most recently, the 47.3 MP D850. I’ve written extensively about the GFX 100 previously, so I won’t rehash that here. Long story short, great camera, but perhaps not the best fit for my shooting style. It produces amazing image files, but with a tendency to frustrate the heck out of me along the way. Without question, I can do everything with it that I can do with my D850. But, in practice, it takes a lot longer to do the same things, and the process of doing them is a lot less fluid. With that said, I invested a pretty penny in the system, so I’ve put in every effort to make that investment pay off.

Ironically, 15 years in, that effort started back at the beginning. It’s been a long time since I first learned the very basics of photography, but the downside of having a lot of experience is that while you get more efficient over time, you can also unconsciously bake in bad habits as well. It’s like doing a sit-up. If your abdominal muscles aren’t strong enough, the rest of your body will find a way to compensate and fool you into thinking you are performing the exercise correctly. You might manage to get yourself fully upright, but in truth, you’re not nearly as strong as you think you are. The same type of effect can occur as a photographer, especially when you’ve shot with one brand so long that you instinctively know how to hide your weaknesses. Certain shortcomings of the GFX 100 highlighted certain gaps in my technical knowledge that I never had to address before. So, I had to do an extended amount of research to strengthen those muscles just to be able to use the GFX 100 properly.

Yet, a funny thing happened. Rather than my newfound technical knowledge causing me to fall in love with the GFX 100, I instead found myself applying those newfound skills to my trusty old Nikon. Suddenly, a camera that I was giving serious consideration to leaving behind was again staking its claim as my favorite camera. Without a doubt, shot in a vacuum, the sheer image quality of the GFX 100 was still a cut above the rest. But, by applying those new skills that had been forced upon me by the new system back into my old system, I was realizing that my existing lower-megapixel camera was perfectly capable of producing files that looked just as good. Some benefits that I had been ascribing to high megapixels were really just a matter of technique.

 Even more unexpected, after a decade and a half of asking how I could get more megapixels, I instead found myself looking for every opportunity to use less. The D850 still ruled the roost, but I added a 24 MP D750 to the lineup for personal use. Applying the same lessons I’d learned while battling with the GFX 100, I soon found myself getting files out of the D750 that, on screen and in smaller prints, were the equal to any other camera in my collection. And I was doing so with a camera body that I personally found more efficient and enjoyable to use.

I suddenly found myself in a position where my most expensive and impressive camera in terms of specs was the one I least enjoyed using. And while, if one were to put the files from all three cameras side by side, there would be a definite difference in quality when pixel-peeping, when I stepped back and tried to just judge the artistic merit of the various images I was creating, I found I was still creating better work with the Nikons. Of course, this is purely subjective and impossible to quantify. I think it was simply something in the working methods encouraged by the design of each camera that allowed me to be a bit more “me” with the Nikons. That could simply be a result of having so many years of experience holding them. That could be the fact that, try as I might, I still don’t particularly love electronic viewfinders. Again, completely subjective, and not an official review that should sway your opinion one way or another. But, for me, the differences felt real and were having an actual effect on my ability to achieve results I was happy with.

But I’m a business man and can’t rely solely on my feelings. I wanted to dig deeper and see if I could apply some more objective logic to which camera I was using and when, so I could make better investment decisions in the future. Like every good education, there was a lot of math involved.  

I am an advertising photographer by trade. So, my choice of camera is not based solely on my personal enjoyment. My clients need image files that can be cropped multiple ways, blown up large from all the various crops, be viewed up close, and still retain their sharpness. So, there is a practical reason why I tend to invest in higher-megapixel cameras and medium format systems.

In fact, part of almost every bid I submit for major ad campaigns is a line item for rental of a medium format system. Generally this is the Hasselblad or Phase One system. The costs of the rental comes from the overall budget provided by the client, so I’ve never felt the need to own these cameras outright. The purchase of the GFX 100, in fact, was partly driven by a desire to retain some of that rental income myself by renting the system to my own productions. But, one way or another, when shooting major campaigns, I’m dealing with major megapixel demands.

But, here’s where the math comes in. While delving deep into my re-education, I decided to do a bit of research to find out exactly how many megapixels were required to make various sizes of prints. This led me to various online calculators that allowed me to put in the megapixels associated with each of my cameras and find out what the largest print was that I could make from that camera using 300 dpi as a baseline. Of course, you can lower your dpi to make larger prints, but I wanted to base my analysis on the highest quality possible.

What I found was this: A 102 MP image in the 4x3 aspect ratio of a medium format sensor could print natively at 300 dpi an image of 38.9×29.2 inches. My 47.3 MP D850 can print a 2x3 full frame aspect ratio print up to 28.1×18.7 inches at 300 dpi. And my 24.3 MP D750 at the same aspect ratio and dpi can print 20.1×13.4 inches. That, of course, assumes no cropping is involved.

So clearly, as expected, the more megapixels you have, the larger you can print before you have to start decreasing the dpi. That’s to be expected. That is what you are paying for when you opt for a high-megapixel camera. And that is why one might want to invest in a camera with more megapixels if they have clients who require their images to be printed large. Or, as is often overlooked in the discussion, if one has clients who want to crop heavily into that image and still be able to print large.

But, I wasn’t ready to put away my pocket protector just yet. Like I said, the majority of my income is derived through commercial photography aimed at advertisers. However, that doesn’t mean that everything I shoot is going to end up printed on the side of a bus. A large percentage of it will also end up in the digital world, in the editorial world in a magazine, in a print for a fine art exhibition, or simply printed for my portfolio. So, I wanted to go back through my work over the last several years and do an analysis of where the vast majority of my images actually did end up being printed, if they were being printed at all. And how did that jive with the amount of money I had invested in increased megapixels?

What I found was that for the bulk of jobs that did require higher-megapixel counts to suit advertisers needs, I was renting medium format Hasselblads or Phase One cameras with higher megapixel counts. Even now that I own the GFX 100, I still generally prefer to rent the Hasselblad or Phase One if the client’s budget will allow it. They just feel more stable when big money is on the line to me personally. And because the type of clients that actually need that level of quality usually accept the fact that they will have to pay for it, it is a financially neutral situation from a business standpoint.

When it comes to the editorial world, the budgets are far more lean. So, while some editorial assignments do come with an equipment budget, many will not. But, if we use our calculations, we can see that a less expensive 24 MP camera or even one with less megapixels is still going to provide more than enough megapixels for your images to look great in a magazine.

Also, while my business is driven largely through commercial commissions as opposed to fine art print sales, I do occasionally exhibit my work. When it comes to prints, I’m a bigger is better kind of guy. So, this is one area where I feel like more megapixels really do pay off. Now, whether or not that payoff is worth it to you is a matter of opinion. As I’m typing this, I’m looking at a print of mine that was exhibited in multiple shows a few years ago, even winning best in show on more than one occasion, and was printed at 24x36. It also happened to have been shot with a 12.1 MP Nikon D700. To be fair, sharpness is not the defining characteristic of this particular image, but of all the responses I got during the shows, no one ever commented on the image not being sharp enough.  

I just made two prints for a fairly prestigious show here in Los Angeles in April. One image was shot with a 50 MP Fuji GFX 50S. The other was shot with an APS-C-sized 24.3 MP Fuji X-T2.  Both were printed at 16x20. Laid side by side, both prints look pretty darn good.  

So, is it worth it to invest in more megapixels? I would say yes if my primary business objective was to regularly exhibit and sell large prints, especially if I was a landscape photographer, for example, and wanted to show every detail of a wide expanse. But as only a small percentage of the personal work that I do (work not commissioned by a client) ends up in fine art exhibitions, and since I’ve already exhibited multiple times with lower-megapixel cameras, is it worth the added expense both in costs and storage space to shoot everything at high resolutions?

The one area where almost everything I shoot has a shot at being printed is in my print portfolio. This is one of my main sales tools and absolutely has to be at its best. People’s portfolio sizes vary. My own print portfolio contains prints that are 11x17 inches. Among those prints are images that were created with everything from 102 MP cameras to 24 MP cameras. There are images shot with Nikon, Canon, Fuji, Phase One, and Hasselblad. They all live together in relative harmony. There are differences in the images. But, I’d say those differences have less to do with sharpness and more to do with variations in my artistic approach based on subject matter. Again, going to the calculator, at 11x17 inches, the distinct advantages of the larger sensors haven’t really begun to kick in yet. If one were to look really hard, you might notice subtle differences in sharpness between images. But, as I learned during my period of re-education, most of that would be due to technique as opposed to megapixels.

So, what is the perfect megapixel count to invest in? Like I stated at the outset, you’ll have to answer that question for yourself based on what type of work you do and where your work will end up. Personally, through this process, I’ve come to think that 24 MP may actually be the best megapixel count for an owned camera system. The files are plenty big enough to handle 99% of editorial assignments, personal portfolio shoots, anything online, and pretty much anything that won’t be heavily cropped and then printed large to be viewed up close. From a business standpoint, you also will save money on upfront costs for the camera body as well as backend costs related to storage. I don’t personally shoot weddings or events, but if I did, I can’t imagine ever wanting more than 24MP considering the sheer number of images you would need to find storage space for at the end of every shoot.

When it comes to personal work or work created for my portfolio, 24 megapixels seems to be plenty, considering that the majority of that work probably won’t be printed larger than the 11x14 to 16x20 range. Again, that’s a generalization. You may print everything and print it all at much larger sizes. I’m just basing that estimate on my own workflow. But, if your own print needs fall into that range, it’s unlikely you will really experience the benefit of more megapixels outside of late night pixel-peeping sessions.

Where you will realize the benefit, however, is shooting client work that might be heavily cropped and/or printed large for up-close viewing. Personally, despite my growing affection for 24 MP, I still continue to shoot most of my images at around 50 MP. Largely, this is because I like to crop and create multiple versions of each of my images for use across various platforms. And, if I am doing a shoot for a client where I’m not 100% sure that they won’t change their mind later and want to order additional and larger usages, it can sometimes be safer to have a bit more megapixels than you need. 

The more I consider the question, the more I wonder if, from a business standpoint, it might make even more sense to limit investment to 24 MP or 50 MP cameras and only rent larger systems on a job-by-job basis. This minimizes your upfront costs while still covering you print-wise for 99% of your personal portfolio, event, wedding, or fine art printing needs. Furthermore, when a client comes around that does need to print in a larger format, you can always rent the necessary camera for that job, bill it to the client, and come out the other side even without ever needing to make a big investment. That way, you can ensure you can meet your client’s needs without overspending on equipment for your personal use or for the clients that don’t need the extra pixels. You can reduce upfront costs and financial risks while still delivering the high-quality photography your clients deserve. The only thing you miss out on is the fun of endlessly zooming into your images in Capture One to marvel at the fine detail. I'll admit that is fun. But, is it the best investment?

So, what are your thoughts? What do you feel is the ideal megapixel count for the type of work that you do?

I love this image. Super spooky, eerie vibe. Fantastic!

Processing is one of the reasons I still love using my D700.

Still rocking my original Canon 5D for personal work. I was surprised with how large you can print with 12.8MP, and I can generally do a panorama if I'm really hurting for additional resolution.

Me too. I really love that camera.

That camera was and still is a classic. I remember the excitement of shooting with one of those for the first time. How many actuations you have on that thing?

I got mine used and I've never checked the shutter count on it (or really, any of my cameras) because I've always figured that when it dies it dies. I'll have to see if I can get a shutter count on it, because now I'm curious!

I think a new shutter (idk if you can find mk1 5d shutters anymore) only cost a couple hundred bucks to replace.

This is a nicely thought out post. It does beg the question of what techniques you improved that changed your mindset. Have you written about this elsewhere?

I too would be interested in the techniques learnt.

Thanks for the suggestion. I'll be sure to address this in a future post.

*Fewer

I saw a Lamborghini the other day. Very nice, shiny black. Top speed, humungous. Parked against the inner city kerb. Speed limit 60km/h.

I suspect that people who buy a Lamborghini do't buy it to drive it at high speed.
I suspect that parking it outside their house has more to do with it.

Fewer

Great post. For the first half I kept hoping you'd elaborate on the specific technical knowledge you'd picked up that helped you apply it to lower MP cameras. Care to elaborate? Perhaps in a future post?

Thanks for reading Iain. I'll be sure to elaborate more on the other side in a future post.

Doesn't author state obvious? There times you need high MP camera and there times you don't. I don't have midframe nor do I have a need for one, but I do enjoy taking pictures with 60MP Sony. And at times I like to take pictures with 24MP A6000 and small lens for portability. And quite often I put 20MP RX100 in a pocket just to have nice camera with me in case I need it. I hate taking pictures with cell phone , so I have Hasselblad true zoom attachment to my Moto Z4 cell phone that converts it to 12MP zoom camera. Any resolution has it's place.

Great a article and great points about print size and cropping. One thing I would say is resolution requirement also comes down to content and viewing distance. A simple portrait can be upscaled significantly as hair and fabric can be sharpened in the process, how landscapes don't fair so well. I would also say higher resolutions are easier to retouch. Dynamic range is also key, newer sensors give much better colour across the tonal range and can be pulled around more with less noise. There is a great point about the shooting process and how the camera effects this. I shoot on Canon and Phase one, they require very different approaches and knowing their limitations is key

Good points. Especially about post work as the process can be very different depending on resolutions and is something people should take into account.

"To be sure, the images I take today with higher-megapixel cameras are far better than the ones I took with my old Nikon D200. But I hasten to say that the improvement is more the result of me being a better photographer now than I was 15 years ago, rather than just an upgraded sensor."

All have been said.

I really can't gin up a need for more than the 24 mp I have now. I've sold 5 foot prints of some of those images. Sure the POD might be rendering them at 100dpi, but none have been returned, and I'm pretty sure they look fine at normal viewing distances.

I once licensed a 24 mp (APS-C!) image to a designer who had it rendered 11x22 FEET for mounting on a ceiling. She was happy.

I do like to photograph birds and for that purpose, I could see having more resolution, but not at the expense of any image quality.

Yes, there are some "if and unless" aspects there. More megapixels might show up faults, in technique, in focus,in DoF, in stabilization ...

Fewer pixels

I grab this shot with my Point and Shoot Canon G11 (10MP) It looked great at 16 X 20

And it should look great because 180 ppi is optimum for die sublimation or inkjet printers. Anything greater than that doesn't look any better even form short distance. Printing press or laserjet would require 300PPI to look good.

The original was a raw file reduced for internet.

If your prints measure in *feet* rather than inches, or if you have the print/display means to take advantage of the 16bit image capture of the GFX100, then for non-studio work where weather sealing can matter and the IBIS can compensate for a windy day, then the GFX100 becomes a tremendous tool. But yes, for other projects (16x20 prints for instance) most human eyes will miss any subtle difference, it it can be reproduced at all.

But if I’m doing a 10 foot panorama print, and with only six overlapping merged shots can end up with an image over 17,000 pixels wide and 11,000 tall (cropped to about 8,500 for a 2:1 aspect ratio for the print), then I have a finished image you can put your nose up to and not be able to detect pixelation. And to me anyway, that extra crispness has an impact worth the extra file size overhead, for anything mounted near eye level.

Yes. The GFX 100 is miles ahead when it comes to printing situations like you mentioned.

What I have learned is it is all about what creates the files for me, it is having Great Glass with a great sensor! I love the old Pentax 6x7, Hasselblad and Medium format lenses, and had the D-850 and it is probably the best bang for the buck, I am shooting with a Sony A7RII and the Nikon Z7 Great Files out of both of them. I do not think the pixel size more than 50 megapixel in a 35mm x 24mm frame will give you the edge. For me I Stitch up to 50 raw images with these cameras using 24 35 45 55 prime lenses giving me prints with incredible detail and the A7RII with Loxia glass is probably the best at this! --- when I need the resolution for wall size prints I stitch, the amount depends on how detailed I want the final image. If I could afford the GFX 100? I am not sure that I would be able to get any better images but if you would like to loan it to me ill give it a try...

Thank you yet again sir. When I was shooting for agencies some years ago, 10MP was (and still is) there baseline for digital photos. Now, as far as J am concerned, 16MP is more than enough for most needs. Although I do have a 24MP camera. Seems to me that people are just wanting (needing,according to their rational) more and more MP and other non-essential accessories to 'keep-up-with-the-Joneses'. Don't tell anyone, but I would love to have the Fuji GFX 50S and/or Hasselblad CVF 50 c ii. Sorry, just can't help it.

My camera acquisitions have always been driven by requirements and not simply to upgrade. I had been shooting for two national clients for years with 24-megapixel cameras. It was only because one art director required at least 36-megapixel images that I bought the Nikon D810. The director was famous for deeply cropping into images despite his wanting me to shoot wide in the studio and on location. With most of my images winding up on the Internet rather than on billboards, there was no reason to go higher than 24-megapixels. Also, regardless of computer power, smaller image files always process faster than larger ones. It's math. When deadlines are critical, clients don't want to hear excuses or technical explanations. I can't imagine my same clients working with shooters manipulation files 100-megapixels and beyond in size. Also, I've yet to hear a client give anyone a reason why a magazine photo or Web page needs images that large.
