    How do I get a smoother "blur" in the background.

    Picture from last week that I had posted:
    I liked how the clownfish turned out in the picture, but the background is kind of noisy, especially where it isn't black. What can I do?

    First, this is a beautiful photograph and I do not feel the the noise has ruin it at all. You can use a brush to soften the background quickly in PS but I think if you bump up the brightness by adjusting the curves, you have a masterpiece.

    I might crop the darkness out in front of Nemo a bit as well.

    The general answer is: faster lenses (i.e. f/1.8, f/1.4, etc.) give you blurrier backgrounds. However, it looks like you're using a macro lens -- you may not be able to find such a fast one.

    But, I wouldn't worry -- I don't find the background problematic.

    If you really want, you could also Photoshop / Gimp / etc. to selectively blur the background. Use an edge-detecting tool (such as scissors, or color selecting, etc.) to get ahold of the background, and apply a gaussian blur.

    Simple answer: Wait for the fish to swim in front of something less distracting.

    Beautiful shot - the noise I see hardly detracts from the photo - nice job!
