I'm not trying to be provocative here, honestly. It's an honest question that I can't for the life of me find any answers to.
If CMOS sensors are capable of rendering an image just like a CCD and the only difference is some color curve that was pre-programmed into the CCD sensor, then it should at least be theoretically possible to create a luminance and color curve that, when applied to a CMOS image, produces a CCD-like look. I have tried to find examples of how to do this but I can't find any.
Maybe I'm not using the right search terms or reading the right posts or something. Maybe someone here that's gone down this road can point me to a discussion of how to take CMOS images and, applying some magic sauce, make them look like older CCD images?
This also leads me to wonder how one goes about analyzing an image for things like luminance curves? I know you can create a histogram from image samples we find on the internet but I'm wondering how you go about figuring out what to adjust if you have a CCD image that you're comparing a CMOS image to. I know there's going to be differences when the image is different. I'm not into creating a lab where I shoot test targets, etc... I'm interested in the real-world differences. Can I take an image sample I find online at some review site and analyze it for what makes it look the way it does, then apply that knowledge to a "similar" CMOS image to approximate the look?
