RAW files vs. JPEGs

Trying to figure out RAW files, the first one is a file shot in raw and edited in raw using photoshop CS2
and the other is a
photoshop converted jpeg.

Any advice to give on editing RAW files?

No advice but I like the richer colors in the RAW files!

RAW gives you the advantage of retaining all of the info your camera can initially collect. When opening the file through Adobe Bridge, double click to start the RAW editor. You can make many of the fine adjustments you would normally make in PS through this app. When you are done, "option" click or "alt" click (for PC) and this will allow you to open a copy of the original, leaving all your original data in place. This will take you into PS where you can do anything you want, as normal. When you are finished in PS, save it as a PSD or TIFF file to retain all your original data. This eats up disk space, but you don't lose anything. JPEGS, GIFS and other files drop pixels to save space. The program is designed to drop only those pixels it determines to be undetectable to the human eye, but over time, overall clarity is lost in color and saturation in exchange for a smaller file size. When you shoot in jpg as a native format (i.e., you set your camera to capture jpg vs. RAW), you're allowing your camera to decide for you what colors to capture and retain based on what's easy for the camera, not what's best for you as an artist. Shoot in RAW as your native, open using the "option" click, edit and save as either PSD or TIFF to retain all your original data. When you want a copy for printing or uploading, do a "save for web" to create a separate jpg to send to the printer. Even high-end printers can't replicate all the colors available to you in the computer, but unless you're shooting RAW native, you start with less to begin with and limit yourself. Now, when editing in the RAW editor, play around with all the options to see what they will do for you. I have found that after using it for a while, I can do almost all of my editing in RAW and not in PS. If you want to know more, let me know.

BTW, you're doing some wonderful work.
