I'm still not sure I understand what .RGB ("Red, Green, Blue")is when used as a photo file extension. It isn't RAW, it isn't JPG or TIFF... I'm just curious to find out if I can get my camera to take photos with any file extension other than .RGB? So far I haven't found anything in the manual (Canon PowerShot S5 IS)
This seems to be the clearest definition I've found so far: "RGB is a file extension for an image file created on a Silicon Graphics workstation. RGB files can contain Run Length Encoding (RLE) compressed or uncompressed images in grayscale or color, and also supports optional transparency." Except that my files are created by my camera, not by a "Silicon Graphics workstation" (which by definition is a computer that isn't either a PC or an Apple).
And I do not know what RLE or "optional transparency" are, either. I'm sure all of this will mean something to me someday, but so far it is Greek!
Well, I will keep googling for definitions and hopefully some of you will keep helping out and eventually I'll understand how all of this will help me take better pictures!
