If so, does that make the R5 less than ideal for astrophotography? To find out, I tested an R5 purchased locally in Calgary from The Camera Store in May 2022. Each pixel is only 4.4 microns across, providing higher resolution but risking more noise. Where the R6 has a modest 20-megapixel sensor with relatively large 6.6-micron pixels, the R5 is (at present) Canon’s highest megapixel camera, with 45 megapixels. In a sequel to my popular post from September 2021 where I reviewed the Canon R6 mirrorless camera, here is a similar test of its higher-megapixel companion, the Canon R5. It has to be a first step on the raw-files from camera and results in a clean and sharp dng-file to proces in Lightroom or ACR.In a format similar to my other popular camera tests, I put the 45-megapixel Canon R5 mirrorless camera through its paces for the demands of astrophotography. I think this could really be an alternative to look into since it really gets rid of noise without effecting sharpness. ![]() I reaaly think this must be the best there is for initial noise-reduction at the raw-level. Yet for my older NEF-files I have found the better alternative in applying noise-reduction at the raw-level by making use of the latest Deep AI technology for Noise Reduction (with remaining sharpness and stucture) from DxO’s PhotoLab 4. I have been a long time user of different versions of Topaz Labs Plug-ins and have found they have really come a long way with their latest versions of AI Sharpen and AI DeNoise. These older Nef-files have definitely more noise than my present FujiFilm RAF-files. Recently however I have not been shooting much but have been reprocessing older images from my then used Nikon D-80 and D-7000. I am more content now with the inherent quality of my raw-files from my FujiFilm X-t20 and X-T4. Selecting all the pictures in the explorer and dragging them into Photoshop does this.Īs a long time user of different types and brands of camera’s I have encountered different levels of noise and/or lack of sharpness. ![]() First, open all the selected frames as tabs. I have selected six frames of the Milky Way that were shot one after the other. Let’s take a look at the simple step-by-step procedure. So obviously there is going to be considerable cropping involved. Second, try to go wider than you actually need to, as we are going to merge and align multiple images. Since we need close to identical frames, this method cannot be used to de-noise images with moving subjects. Usually six to eight frames will be good enough to produce desirable results with the minimum being at least two. The quality of noise reduction gets substantially better as the number of frames increases. If not exact, at least close to identical frames would be required. Requirements and Limitationsįirst, we need multiple pictures of the same composition. Let me get you through the conditions before we proceed to the actual noise removal. But there are a few conditions that need to be addressed and like most other approaches, it has its limitations as well. Using smart objects is one of the most effective ways to reduce noise without compromising the sharpness of the image. That is primarily because most noise reduction algorithms cannot differentiate between noise and sharp boundaries. When we try to reduce noise, the software ends up softening the overall image. That is one of the major setbacks when it comes to using noise reduction software, apart from the fact that noise reduction plugins are either too expensive, or they don’t yield desirable results. Sharpening and noise reduction in post-processing have mostly been reciprocal to each other. The Effect of Noise Reduction on Sharpness ![]()
