1) I have shot in RAW in the past and haven't actually found a difference between that and JPEG o___O 2) They take up soooo much space. I had to convert all my RAWs to JPEGs anyway a while ago because I was running out of room on the computer.
It is amassive difference, your images contain more information in RAW than jpeg, a LOT more. Trying edit a RAW file then saving it as a 16bitTIFF at output and do any touch up in 16bit....and it is just really a BIG difference. Besides, storage space these days is next to nothing. And jpegs lose quality.
I will try....if my pc can handle the size of the program/pictures. I'm probably gonna need help with the RAW program, and for that I either need a manual or someone that knows what they are doing. I might actually have a RAW program laying around somewhere in the back of my pc...
That is no problem at all. It is easy, all you do is adjust the RAW image, then 'export" out, you can export as a jpeg, if you need to do more PS work it is best to export out as a 16BIT TIFF file then, but when it doesn't need any more reworking jpeg is fine.
Picasa is ok to start with. What camera do you have?
