And be a reminder of what you had in mind But the camera captures a full color image. Later you convert them in the adobe raw filter or in Photoshop. This gives you live filtration which amounts to a renaissance in black and white shooting. You can get results you could not get before if you used for every shot you took every filter ever made in turn and in combination. There are a bunch of color sliders each one representing a filter and your seeing the results of their application live. But you're using groups of them (more than one of course) at various levels as you watch the images change getting the effect you want live. Its quite rewarding and quite fun I do it hundreds of times a week but on the LUG all hear is its too much trouble. Its not instant. You have to think. You have to do stuff. But you get to take control of the look of your image like nothing ever before in photography. So when you say "I made this picture" its more rewarding becuae you didn't just go "click" when the thing happened and then pick it up from the drug store. Or the digital equivocate of that. Which is shootin jpegs and using them right out of the camera.
