Okay so with my current DSLR (Canon 60D) I shoot all my images in RAW which means they have the .cr2 extension when I copy them to my computer. After editing them with photoshop I can't re-save them as .cr2 so I need to pick a new lossless format. Currently I'm using bitmap (.bmp) but I wanted to know what some of you're expert opinions were.
Thanks!

I personally save everything, post edit, as PNG, or TIFF. And keep the originals in .cr2.

Thanks for the link.

photoshops own .psd will be about as lossless as it gets. Aside from that, I generally stick w/ .tif.

Convert to DNG, or use something like Lightroom which doesn't touch the raw file and stores all changes in an XMP sidecart file.

I'm pretty sure PS saves all the edits you make to a particular RAW file by creating a secondary file (which I believe is hidden) in same directory as the original file.
