Q&A

Q1: What's the difference between Smudge and Blur?
A1: The main difference is in the way you apply them. Smudging, because you're moving the pixels from point A to point B, tends to show the direction of the move. Blurring decreases the contrast between adjacent pixels, so they seem to blend together visually but with no hint of movement.
Q2: Can I saturate and desaturate on the same object? want to make one side lighter and the other darker.
A2: Of course you can, but the Sponge tool might not be your best choice for darkening an object. Remember, it makes the color more or less saturated, which is not quite the same as darkening it. Try it, and if the effect isn't what you're looking for, try burning instead.
Q3: I understand the Sharpen tool, but there also seem to be Sharpen filters (Okay, I peeked ahead.) When do you use the tool and when do you use the filter?
A3: Use the tool when you have a small area that you want to sharpen. Use the filters when you have a soft focus image, or one that needs all-over sharpening. You'll learn how to work with the filters in Hour 14, "Filters That Improve Your Picture."
