IV

The roman numeral four. Intravenous. And, in this case, the misspelling of ivy. That's a silly way of introducing yet another picture of ivy leaves. This one was, as you might have guessed, taken with one of the new magnifying filters I just got. It's part of the first batch of photos I've done with the +4 filter.

As spring approaches, the ivy starts to climb. 50mm +4 mag, f/4.5, 1/125s, ISO 2000.

One of my readers, CHM, made a comment on Tuesday that got me thinking about focus stacking. That's a technique used to make macro images (although not exclusively) come fully into focus. It involves taking multiple images, each focused on a different part of the subject, and combining them so that the whole subject is in focus. It's an effect that's nearly impossible to achieve with a single image because depth-of-field is very shallow in macro (and other close-up) photography. The multiple images are then blended, or "stacked," in post-processing using software like Photoshop. The technique requires using a tripod and being very careful not to move the camera in between each image. Maybe I'll play around with it. One of these days.

  1. Focus Stacking sounds fascinating. I can't wait to see what you create.
