TIFFS, JPEGS, PSD's

Can someone break this down for me? What is the difference between TIFFS, JPEGS, and PSD's. I don't even know what they stand for? I know that I have always converted my RAW to JPEG (been doing it that way for years, hence why I do not know what the others are...don't laugh).

Thanks for any help.

Re: TIFFS, JPEGS, PSD's

They are all different image formats based on different algorithms for storing digital image data.

PSD is photoshop's native format and is considered lossless.
TIFF is an older uncompressed image format and is lossless
JPEG is a newer algorithm that provides a lot of compression for images but is considered a lossy for of compression. This means that each time the image is re-compressed image data is lost. Recompression occurs when a jpg is open for editing.

Actually, the compression takes place when saving the file. Just opening the file does not recompress the image. Otherwise, every time you looked at a jpeg file would cause it to degrade over time, and that's just not the case.

Definitely edit in raw first, before you turn it into a jpeg. You'll have a lot more "room" to edit if it's done in raw (or tiff).

Just perfect answer has been given here. I would want to add here that, consider .PNG format as well.
