Focus-Stacked Macros

  1. What is the advantage of this method over using, say, a macro at f 45?

    It might be interesting to have an image composited that had two areas of focus at different distances, and the rest somewhat out of focus. As, for instance, if you wanted to spotlight a couple of people or animals in a crowd. An art director in advertising could have fun with that.

    I’ll be interested to see the different “tweak” options on this process that Photoshop offers. Love working with these special effects!

  2. An obvious answer to my question would be that shooting with a wide open aperture lets in much more light and keeps down the danger of shake or subject movement. One could theoretically shoot a bunch of shots at f 2.5 or lower, and probably have different sensitivity to light than at higher f stops. Just a thought …

    1. I’ve thought something like what you suggested in the first comment would be cool. However, the movement of crowds, etc., might make this technique harder (but not impossible.) You would have lots of ghosting and blurring, but even that effect might be cool.

      As far as a macro at f/45 is concerned, that would certainly give you the sharp image, but in most cases the entire image would be sharp. This looks like it would be good to selectively sharpen certain parts of the image.

  3. Speaking of ghosting, I did some multiple exposure shots once at The Ted in Atlanta. Looking down on crowds entering the stadium. I shot a number of shots onto one frame of film. The images did indeed have some ghosting – like what I’d think could be used in a Stephen King movie about people who are not quite solid.

    1. You’ve actually given me an idea. I’m going to take the camera to a crowded area of Charleston after dark (Meeting Street with the restaurants?) and take several long exposure shots. It will be interesting to see what happens when these are stacked.

  4. If you could capture the changing light, too, it’d be interesting to see what that might lend.

    Charleston can be a remarkably fun city to photograph. For instance, some of the reflective spherical ornaments give cool wide angle reflective photography. And such a variety of subjects.

  5. Tom, I think your idea of the crowds in a long exposure could be really interesting. Kind of like the light trails from a highway. Just blurs of people where the buildings stand.
