Are high-resolution images created from multiple images taken by the camera a gimmick? Is it possible that they can actually create higher-quality images? But isn't it too difficult to shoot and process these images? What about all the storage space that they need? All your questions are answered in this video!
In this detailed and insightful video, Richard Wong introduces us to high-resolution multi-shot Mmode images (images that have a higher resolution than the sensor's pixel count, created with pixel-shift technology). This is a feature that more cameras seem to have these days. However, the way it works on some brands is rather complex and difficult to understand unless you try it out yourself. Shooting suitable subjects, processing the images, and analyzing them can take a long time. Wong does this work for us.
This detailed video first analyzes whether the process itself is worthy of attention or whether it's a gimmick. Spoiler alert: there is a boost in quality, so it's not a gimmick. Unfortunately, the whole answer is not as simple as that, so we need to watch the rest of this video. There are complexities to navigate, moiré, weird colors, and image softness. Which cameras do it better? Can it all be done in camera? Spoiler alert: some camera brands do it better than others. I did say that this was a detailed video!
Wong goes on to analyze the strengths and weaknesses of this technique. What happens when there is movement? Can you shoot handheld? What happens if overexposed or underexposed? What's the dynamic range? What are the circumstances when it makes sense to use an AI image-upscaler instead of multi-shot? Are AI-upscalers better than multi-shot high-resolution images in some instances?
All this and more has been explained in detail in this video, which answered more than a few of my own questions about the process.
Haven't seen the video yet. Let's just say it's for the photographers and wall or building-size photos. I just sent away a 5.6mp photo for a 20"x30" (50x76cm) to an ordinary online printer. It looks really good even close up with nice detail.
I was under the impression that pixel shift was only suitable for subjects that don’t move such as architecture and to a degree landscapes. The best examples I’ve seen are interior images of cathedrals.
One area that it can help in is pixel shift tiled images for mega scan textures. Which is good for 3D renders that don't need to be rendered in real time, since it will behave like real life in terms of level of detail.
