How do you save your files - better yet why?

I usually save mine as JPEG. Should I be considering Gif?

Short answer: Oh hell no!

ETA:
JPEG stores each pixel using 8 bits per channel, giving 16 million possible colors; there is lossy compression, but if saved at a relatively high quality, the effects of compression are not easily visible.
GIF is a "palette based format" and is only capable of storing 256 colors per image block or frame. It is theoretically possible to store a true-color image in GIF form, but it would be very large. GIF is normally only used for line-drawing type images, which store very compactly in this format, r sometimes for frame-animation videos.

No, you should be considering TIFF. I assume you are talking about your final composites.

GIF files are in Indexed Color -- a much smaller gamut than JPEG or TIFF which use some version of RGB (or Grayscale). TIFF with LZW compression is lossless, as is JPEG when saved at the highest-quality level in Photoshop CS2 or later. Use these for composites/printing/placing.

The only reasons for using GIF today are for small animations or if you need a transparent background.

To be more clear. The company that is developing the website for the company that I've been hired to take pictures wants the photo's in RAW...ahhh I'm not comfortable with that. But they cringe at the mention of JPEG. So that leaves either Tiff (not an option in my save for WEB) or Gif (I thought was similar???).

Thoughts?

Yes, just do Save As and choose TIFF. To give them the most latitude in adjustment choose 16 bits/channel. Note, the files will be quite large.

Why are you not comfortable with a RAW file?

When you save as TIFF, it gives you a couple op[tions like JPG does. Tell it you don't want to compress the file, mainly.

After I get done with my edits how would you save it. If they don't want it in JPEG?

TIFF, as previous. But here's the thing; the reason THEY want RAW is because they want to control the image parameters themselves. YOU want to "edit" it and give them the edited image, which I understand, but a LOT of what we do for personal editing is not acceptable for publication usage: too much sharpening/smoothing, too may artefacts created in HDR processing, halos etc, you name it. So they are leery. You gotta be careful, and you'll have to work with them on this.
