I've working in photoshop for years now and built websites, but i'm noticing that some websites that graphics look absolutely amazing. they're rich, vibrant, and vivid. compared to making cool graphics in photoshop and then saving them as .gif's or .jpg's, these seem to be completely different. look at this website for a sample of what i'm talking about:
click on some of the icons on the right to bring up some of their artwork. these images are clearly different than the logo on this site, for instance. they're crisper, sharper, more clear, etc. HOW?? I have no idea what software is used to make images like this. Is it photoshop? maybe it's just the format of the images? i'm not sure. can someone help explain this to me...the type of image and they software used to create it. and how they save it for the web and screen presentations. i'd like images like this for some presentations i'm working on.
