Shooting in Darkness Without a Tripod: A Step-by-Step Guide to Prevent Noise When Using a High ISO

Have you ever been to a dark location where you couldn’t use a tripod? You probably needed a very high ISO and accepted the high noise levels. With this step-by-step guide, you can prevent the high ISO noise without the use of specialized noise reduction software.

When you are photographing in a dark environment, you might want to use a tripod or a flashlight. But some situations don’t allow the use of a tripod or flash. Or perhaps you didn’t take a tripod or flashlight with you. In that case, there are a few possibilities left. If your camera has image stabilization, you can make use of that option and take a picture with a very long shutter speed. Or you can bump up the ISO and accept the higher noise levels.

High ISO values will result into noise. The amount of noise will depend on your camera. This is the result of a Leica SL (type 601)

A lot of cameras produce acceptable images with ISO levels that reach up to ISO 6,400. Higher ISO levels are often very noisy, with loss of detail and colors. You might accept the result, just to have an image of that memorable moment, and perhaps you can use specialized noise reduction software to get rid of the extreme noise. Often, it leads to soft images with further loss of detail.

There is a way to get a low noise image, even with an extremely high ISO level. For that, you have to shoot a series of photos of the subject. Small movements between the images can be easily corrected, so there is no need for a tripod. This step-by-step guide will help you. We’ll start with part one, shooting at the location. Next will be part two, the post-processing. For that, you will need to use Photoshop.

Every camera will allow you to set boundries for the ISO level. With the technique as described in this article, you might go beyond your comfort zone.

Part One: Shooting at the Location

For this method, you will need to shoot the necessary images at the location. There is no need for a tripod or flashlight. Just make sure your shutter speed is fast enough to hold the camera still.

1. Choose the Right Camera Settings

Use your camera in the way you like. Choose the aperture you want and a shutter speed that is fast enough to prevent camera movement. Bump up the ISO level as high as necessary. Set your camera to continuous at the highest speed. If you have image stabilization, turn it on. For this example, I have used my Canon EOS 5D Mark IV at ISO 25,600.

2. Make at Least 10 Images, Preferably More

Make sure you stand in the most stable position possible. Make your composition and shoot a burst of images. I would advise you to shoot at least ten images, but more is better. There is a moment when your camera buffer is full, and the speed will drop significantly. That is often the best moment to stop. Some cameras have a buffer that can hold hundreds of images. More than 20 images are often not necessary.

Part Two: Post Processing

I am using Lightroom for my post-processing and Photoshop for noise reduction. You don’t need to use Lightroom, but you do need Photoshop for this method. I use the Dutch version of the software, but I think the steps will be obvious.

3. Open Your Images and Perform Your Post-Processing

I use Lightroom to make the necessary post-processing steps. Don’t bother about the noise levels, but you might want to set sharpness to zero. Whatever you do, don’t perform any noise reduction. Keep the noise the way it is.

You can perform your post processing, but make sure you don't use sharpening or noise reduction. Leave those values at zero

In Lightroom, you can post-process one image and copy the settings to the other ones. Make sure every image has the same post-processing before you continue.

4. Open All Images as Layers in Photoshop

Lightroom makes it possible to open a selection of images as layers in Photoshop. Just select the option from the menu. If you don’t use Lightroom, you will have to open all images in Photoshop yourself and stack every single image as a layer on top of each other manually.

If you are working with Lightroom, you can open all selected images as layers in Photoshop.

5. Align the Layers

Because the images are handheld, the alignment is far from perfect. Fortunately, Photoshop has an option to align layers automatically. For that, you have to select all layers by pressing the top one, holding shift while selecting the bottom one. Next, select Edit from the top menu and choose Auto-align layers. The popup window allows you to choose different projections. Select Auto, and deselect the lens correction options. Then, press OK. This alignment may take a while, depending on the number of images, the image resolution, and the speed of your computer.

Select all layers and auto-align all layers. Let Photoshop do the work for you.

6. Make a Smart Object

The next step is converting all layers into a smart object. You can find this option by selecting the menu Layer – Smart Object – Convert to Smart Object. Again, this might take a while, depending on the number of layers you have. Just be patient and wait until Photoshop has finished.

When the layers are aligned, make a smart object.

7. Stack the Images Together With Median

Now comes the magic. You have to stack all layers inside the Smart Object with the option Median. Just open the Layers menu again, and select the Smart Object. There, you can find different stacking options. Choose the option Median and wait until the images are stacked. After the stacking is completed, the noise in the resulting image will be almost completely gone. 

Stack the layers in the smart object with the option median. This way all noise will be eliminated

8. Rasterize the Image and Save It

You are almost done. Unless you are planning to keep the stacked Smart Object for further processing, you can rasterize the image, turning it into a regular layer. Just save the image in the file format to your liking. If you started from within Lightroom, saving the image will return it to Lightroom again.

If you are ready, rasterize the smart object. You can keep the smart object if you like, of course. It will allow you to change the image afterwards.

The Result

After you are done, compare the image to one of the originals. You will see how the noise is removed and the details have become visible. There might be a bit of noise left, but that can be removed with ordinary noise reduction inside Lightroom of Photoshop. How far you can bump up the ISO with this method will depend on the camera and its ISO performance.

Just compare the end result with one of the images you used for the stack. This can be done in Lightroom. As you can see, details have become visible now the noise has been removed.

This method can also be used with lower ISO levels and with a camera on a tripod, of course. It will result in very clean images, which allows you to use more extreme post-processing techniques. I use it for my drone photography and astrophotography. But the beauty of this is the ability to use a camera handheld at extremely high ISO levels without the noise levels. Just try it out yourself.

I used this technique on another image, with post-processing performed. The post-processing resulted in an even higher noise level. But after the stacking the noise became acceptable.

Just keep in mind, this method only works for non-moving objects. If you have movement in the frame, it might result in strange effects. On the other hand, a person moving through the frame will become invisible also.

What do you think? Have you ever used this method before? If you do, please share your experience in the comments below. I would love to hear about it.

Your article did not mention what shutter speed you were shooting at. I assume it was below 1/60 sec, the reason I bring this up is because IBIS is actually makes images shot above 1/60 sec worse..

Black Z Eddie .'s picture

Shutters speed is right on the top left of the images. 1/320 to 1/400.

Yeah, no, I'm not sure about the "IBIS is actually makes images shot above 1/60 sec worse".

Troy Straub's picture

Yeah, that seems pretty wrong to me too. If you couldn't shoot above 1/60 without degrading the image no camera would have IBS.

Nando Harmsen's picture

Why would IBIS make images with shutterspeeds above 1/60 worse?

Billy Paul's picture

"IBIS is actually makes images shot above 1/60 sec worse"

Sure, because it would be far too complicated for camera manufactures to turn off IBIS when the shutter speed is faster than 1/60th (if what you say isn't BS).

That was somewhat of an issue with the very first generation of lens stabilization.It hasn't been true for the last three or four generations of IS, and I doubt it was ever true for IBIS.

An interesting technique which I hope to try.

dale clark's picture

Very interesting technique. Thanks for sharing

What would you recommend for producing an image file that is as close to "raw" as possible but with the reduced noise? I would prefer not to archive 10 shots if I can, instead, produce a noise-reduced version that otherwise has most of the flexibility of a raw original.

Nando Harmsen's picture

That is easy. The result form Photoshop can be saved as a 16bit TIF file. I think that is the best option. You can keep the layers, or merge the layers before saving it.

I used a similar technique but not as complex years ago to eliminate tourists from The Field of Miracles in Pisa. It worked well for me. I will try this.

Nando Harmsen's picture

Indeed, that is also possible. Another possibility for removing tourists is the use of a dark neutral density filter. But you definately need a tripod for that.
