How To Shoot Fireworks

(Originally posted on 2016-07-06)

This is why you should use a camera with a bulb setting. You open the shutter when you hear the first pop, and close it when the light dims to get something like this:

Lens Compression and Lens Distortion

(Originally published 2016-03-16 as /archives/10930)

This lens-compression-thing: we all agree on it correct?

Lens Compression

The definition of lens compression is this: if you use a longer focal length, then the background will appear to be closer to the subject. There are numerous examples of images that “prove” this out there (including the GIF below), but guess what? Lens compression doesn’t actually exist.

Here’s how the prove-it examples work:

  1. First the photographer makes a photo of a subject, standing in front of a background object, with a short focal length lens (wide angle, less magnification).
  2. Then the photographer takes the same picture, of the same subject, at the same distance from the camera, but with a longer focal length lens (telephoto, more magnification).
  3. Then we compare the two images, and note that the background object appears to be closer to the subject in image #2.Here’s the kicker:
  4. If we then crop image #1, so that the subject takes up the same amount of space in each image, we will note that the subject now looks to be the same exact distance from the background object as in image #2.

In other words: lens compression is just an optical illusion.

Lens distortion

Barrel Distortion, Pincushioning, Bokeh, etc., may be different with each of the two lenses. Generally the wider angle lens (shorter focal length, less magnification) will distort the image more and cause more foreshortening relative to the telephoto lens (longer focal length, more magnification), but not always. A lot depends on lens design, and post processing software is really good at removing distortion these days.

The following GIF was shared at “reddit /r/educationalgifs How different lenses affect portraits“. It shows the foreshortening issue and the so-called-lens-compression-issue at various focal lengths of a telephoto super zoom lens. For many people this will be proof that lens compression is real. It still isn’t real, and not all wide angle lenses will cause such drastic foreshortening.

OK: so if the focal length is changing, then why is the subject’s head mostly the same size? Because the photographer is moving physically closer to the subject, for the wider angle shots, and farther away for the telephoto shots.

Back to the Lens Compression Example

OK, so Paul must be wrong about lens compression. I mean look at how that tree in the background of that GIF moves closer to the subject: right?

In the following video, Dieter Schneider does the steps (from above) to prove that lens compression does not exist.

Scott Kelby: Two Lights, One White Background

(Originally published on 2016-03-28 as /archives/10922)

Scott Kelby made this video for Westcott, but it’s good information for everyone.

The next step would be to consider adding weak lights behind the subject: either to light-up the background, or to highlight the subject’s hair. A third light isn’t needed here, because the white backdrop reflects so much light.

The “Hers” blog Facebook page has a “Posing for one” guide.  I think that the negative reader comments are interesting:

The right way to make some one look better ????? In who’s eyes !!! That’s awful I’m sorry but this wrong on so many levels…so thinner arms make the shot better ??? Really come on this is hiding who you really are it’s as bad as photoshop …if you have fat arms or belly or bum so what you don’t look any less sexy ..in fact if you show your flaws and own them with confidence there is nothing more beautiful or sexy than that !!!!fact!!!!

This is silly. People, love yourselves for who you are, not for what you think is the socially acceptable version of beauty.

She looks thin whatever pose she makes cause SHE.IS.THIN

When you put a set of images in front of a subject, which ones do they want? The ones with the better poses. Plus: posing-well is easier, and more accurate, than digital editing.

Here are some posing and portrait guides from Digital Camera World:
