Re: RAW, JPEG - bit depth and data loss from using JPEGs
In reply to pris, Feb 13, 2013

Pris

The OP (not I ... ) asked this question here:
http://forums.dpreview.com/forums/post/50816419

" Up to this point have been shooting jpeg but I have been thinking about shooting raw. Does anyone know of any resources where I could learn more about raw and photo-editing? I have the cd that came with my evolt 510. Is that worth using? "

I responded, encouraging said OP to explore this use of his camera here:

and gave a number of references as to where he might be able to further his knowledge and have his question answered by others.

I further responded to a post that contained patently wrong information here:

If you want to argue that JPEGs are the equal of, or superior to, RAW files for your purposes, by all means, do so. May I suggest that you address that to the OP's question, if even just in passing, rather than taking single phrases out of my posts and arguing about that particular phrase with me?

I have stated my position to the OP that I (much) prefer working with RAW files. I have clearly stated some of my my reasons for this preference. Those reasons may be of little or no consequence to you. That is also fine - it's your choice.

I did not come to this thread to have an argument with you as to what you may, or may not, prefer. That is for you, and you alone, to decide.

BTW, my contribution to this discussion is aimed at the conversion of a RAW file, and what can be done to it without data damage during that conversion. Once it has been converted to an image file, I always convert it to either a 16 bit TIFF or PSD file, depending on where it is going to end up. I keep the colour space (gamut) as wide as possible.

These file types are utterly unlike JPEGs and similar to the original RAW in that they are compressed using lossless compression. As I have already said, they also support 16 bit, wide gamut colour spaces, which JPEGs at this time do not.
