I have mentioned this tip before, but it is worth repeating. If you are shooting through a chain link fence, or similar obstruction, try opening the aperture on your lens as wide as possible (assuming you have that control available to you). Then place your camera right up against the fence, and the fence wires will just disappear. It’s physics!
This is Park Avenue in the Bronx, with the Metro-North Train tracks running through it. I was walking across 188th Street to meet my family for dinner at a restaurant on Arthur Avenue in the Belmont section of the Bronx. This was taken with the Fuji x100 with the aperture at its widest setting f/2.0. I’m not sure how wide open an aperture needs to be for this effect to take place, and I believe it is affected by other factors such as the size of the lens, the amount of light available, etc. Here is another image taken with the same settings, but I stepped back about a foot away from the fence, which starts pulling the wire lines back into visibility.
If you want to experiment at home, use your best fast aperture lens — a prime that goes to f/2.0 or wider is best. Hold a pen or pencil directly in front of the lens, and take pictures at a variety of f-stops, from f/16 on down to below 2.0. You will see the pen gradually become fuzzy, indistinct, and eventually disappear.
Sometimes you want the fence in the picture, and I kind of like he look of the second image, but it’s also good to have options.
