Stop!

Stop down if you want even brightness across your image.

Or, on the other hand, open your lens to the wides stop if you want vignetting – often, for instance in portraits, it is an advantage.

Here is my ceiling, shot with my Canon 7D, with the 35mm lens fully open at f/1.4:

And the same shot at f/2.0, just one stop from fully open:

IMG_2219

Can you see how the first one is vignetted, meaning it is darker along the edges? Save both images and flip rapidly between them, if it is not obvious to you here. You’ll see the difference, I promise.

(Yes, and this is on a crop camera. Let’s debunk the myth that this only happens on full-frame cameras.)

So: want vignetting? Then open your aperture all the way. Or want even brightness? Stop down by one or two stops.

When to look for black and white?

It seems almost too obvious, but one time you may want to consider going to black and white is… when you see strong blacks and whites. Like in this shot I made at a recent wedding:

MVWS9604

Strong blacks, strong whites, nice greys, and an off-centre composition. That makes this shot, wouldn’t you say?

Assignment: shoot one photo in black and white today. You can shoot in B/W in your camera or do it in Lightroom/Photoshop/etc.

 

Try not to drop

Your camera plus lens ($2,000 each) on a hard concrete floor. The long strap pulled it down.

Lens dent:

Top left, see? That hard steel rim is now dented.

The lens seems ok… but is it really still perfectly adjusted?

Of course I had the hood on. Always use hoods! The hood scratched and came off, but it did no doubt soften the blow. A bit.

Ouch

Mmm. I dropped my 7D onto a concrete floor today at the Royal Agricultural Winter Fair I was doing portraits at. It bounced and was dead for a minute until it restarted – kudos to the 7D.

The 16-35 2.8L lens is dented. It all seems all right – but with a seriously banged about camera and a living that depends on it, this is basically $4,000 I can no longer trust. More than I make all month this month- this is definitely NOT my day. Yes, I can drive it all to Canon for a two-week CPS checkup. Problem is, first free day is in December. And I need the lens until that time, constantly.

Goes to show why we al have redundant equipment. Never rely on one piece of gear!

Juxtapose!

One thing we as photographers always look for is juxtapositions. Things like:

  • Red vs green
  • Blue vs yellow
  • Old vs new
  • Large vs small
  • Clean vs dirty
  • Square vs round

Or as in this case: conservative Islamic vs Western liberal:

Yes, that is the Great Pyramid.

Any juxtaposition makes us think “this is interesting”. And that makes for an interesting picture. So today’s tip: Whenever you see any kind of juxtaposition, have your “contrast-detector” go off, and ask yourself: “could there possibly be a picture here?” If in doubt, shoot!
