I'm a bit disappointed in the noise level when shooting stills at ISO 800 with the R5C. Or is this the expected amount of noise in a raw file? Please see the two photos, one straight out of camera and one with Lightroom Classic AI noise reduction, both converted to JPG 60%. Zoom in tight and check out the eyes and lips. Thanks.
Greetings Steve,
The image does not appear to be representative of the R5 C's ISO capability at 800.
Can you please provide information about the shooting conditions? Lens you were shooting with and settings? The image doesn't look to be in strong focus. Also what firmware are you running on your camera?
This is ISO 1000. I shot this through a 1/2 in mesh cage.
Check this thread as well. I have a few indoor cathedral shots. One is ISO 12,800.
I have the R5 instead of the R5C, but I hope some of this might be helpful anyway.
If you look in the metadata of the CR3 file for camera temperature, then you might find that noise increases with increasing temperature. Noise will be more noticeable at a lower ISO.
To display the camera temperature, one may use exiftool:
exiftool -G0:2 -s -"CameraTemperature" IMG_*.CR3
Camera temperature increases with increased ambient temperature and with increased use of the chips inside the camera. If you are going to process the CR3 file in software other than Canon DPP, then you might turn off "Digital Lens Optimizer" in the camera menu since this uses a lot of CPU time and that will raise the temperature.
It seems to me that if any of ISO, shutter speed, or aperture are auto, then there is increased noise when one enables "Auto Lighting Optimizer" or enables "Peripheral Illumination Correction" in the camera menus. If you are going to process the CR3 file later, then it seems to me that these corrections are better done later and not in camera where they are saved to the JPG and not to the CR3 except as a recipe.
Setting "High ISO Speed Noise Reduction" to "Standard" in the camera can give one an idea of what value the camera would have chosen for noise reduction without increasing the processing time as much as setting it to "High". More processing time means more heat.
During a recent trip to a wildlife refuge to photograph birds, out of about 380 photos, 2 had the lowest temperature that day of 27 C and 8 had the highest temperature that day of 46 C. Early in the morning before the sun was up and before I had used the camera much resulted in the low temperatures. Later in the day when it was hot out shooting difficult to focus far away birds in hazy atmosphere which made autofocus difficult resulted in the highest temperature. Shooting bursts of flying birds also raised the temperature.
A caution from the camera manual:
“ I'm a bit disappointed in the noise level when shooting stills at ISO 800 with the R5C. Or is this the expected amount of noise in a raw file? Please see the two photos, one straight out of camera and one with Lightroom Classic AI noise reduction, both converted to JPG 60%. Zoom in tight and check out the eyes and lips. Thanks. “
Please, bear with me as I try to understand what you are saying. I am not familiar with that phrase “JPG 60%”.
Both photo look soft, to me. This may be due to how the forum treats uploaded images. The images are very low resolution, 666 x 999. Files size is well under 200k. You can post higher resolution photos by reducing the bit depth. Web pages do not need more than 8 bits.
If you wish for someone to take an honest, critical look at your image, then please post the RAW file to a download site like DropBox.
