Hello, I always save my projects in the native .psd photoshop document format. This is always helpfull in the future for editing, it saves the layers and channels. If I want to output a image I use the Save a Copy option and then convert it to whatever format I want. Tiff is good if you need to have channel info inside your file, Tiff can compress the alpha channels. Another advantage for Tiff is that it travels from Mac to PC rather well. JPG is good for web images, I always flatten the image and delete alpha channels that the JPG will not need before Save a Copy. The only time I convert to Gif is when I need a transparent color on the image or want to animate the Gif. Saving as Gif turns the mode into Indexed color that only has 256 colors so this is a given. If your file has a lot of one color, like say a high percent of blue, select the majority of the blue before you convert to Indexed color. This will force the new 256 pallet to use the blue as the major shades. Then you could save to Gif. I sometimes get better results this way. Serpent
