RGB Combine - or RGBHOO etc
Hi, When I use the RGB combine tool with a formula like RGBHOO or the others, does signal to noise ratio improve? as compared to just using the split R, G, B files? Is there actually more data in the final image?
I am still a newby and this question crossed my mind.
Your SNR (signal to noise ratio) will marginally improve as you combine two images each for one RGB channel, e.g. your R and H frames both would contribute to the R channel of the final image. Note that the improvement will only be marginal though, the SNR will be a factor of SQRT(2) better (roughly by 1.41).
Best regards & CS,
