Best format for saving digital photos

[Johnn]

I recently switched to digital after shooting film for a few years and I keep the original large jpeg format, but also an 800x532 of the good ones in a .png, should I keep them as a .tiff after resizing them in photoshop or is .png ok? so far it seems to be working fine but any advice would be appreciated.

I often end up with several copies of my digital files. First I have the RAW or large JPEG file from the camera. These are saved as-is (like negatives). Then if/when I edit them, I will often save a working copy is a lossless format like TIFF or PSD (photoshop). Then I save a resized and compresses JPEG for uploading to the web and maybe a copy that has been processed for printing.

for the archive i use RAW only + TIFF 16 bit if I made changes in photoshop.

But IMHO it is rather easy to redo the changes in photoshop, but it is impossible to get back to the original (RAW) data if you did not archive it.

The final output for printing or the web in my case is usually jpeg with almost no compression.
