Light note

As far as available light goes, you can have dramatic, contrasty light, or dull, even light.

The latter, dull/even cloudy day light here at McDonalds the other day:

But then that dull light turned into dramatic light with a shaft of sunlight:

You want the dramatic light for this kind of scene, I think you will agree!

But for the next example, a photo I just took for a realtor, you need the earlier, even light. You do not want to emphasize a part of the house, you want to light it evenly; in fact you want it expressly without any drama:

The same goes for the child:

He was in the sun, which is bad not just because he squints, but majorly because sunlight is dramatic and has excessive contrast and dark shadows. Just like on the house, you want to avoid that; so we had to use the shoot-through umbrella as as scrim, holding it right in between him and the sun, as well as as a flash umbrella (neat trick, eh?)

So there is no right or wrong about light. it’s not “what is good/bad”; it’s “what suits this photo in question”.

 

Sic transit gloria mundi

Thus passes worldly glory… we are here for a limited time. Hence, make the most of it while you can. And especially, make photos. Or better, have them made, by someone who does it for a living.

This kid’s mom is a very good photographer, and I shot her boy with her yesterday:

(As usual, I used an off camera flash, and the speed was the usual “outdoors starting point” of 1/250 sec at 100 ISO; the aperture needed to match this was f/4.5, which also gave me the blurred background I wanted.)

I often hear “photography is dead”, “from here on, we are all just doing iPhone snapshots”, and so on. But looking at these, do you believe that?

I am sure that there will always be a market for great photos, photos that this young man will treasure when he is my age. An iPhone cannot give you blurred backgrounds, sharp images, lens choices, or the use of flash.

For this image we want a dark background to get saturated colour. That is the 1/250 sec at 100 ISO and f/4.5.

Then for the subject we want a flash: after all, “bright pixels are sharp pixels”.

To be bright enough, the flash was set to half power shooting through an umbrella, so:

A single speedlight is enough in this kind of light. If we had been in the bright sun, the speedlight would have to be very close and/or unmodified.

In any case: please have images like this made, or learn how to make them. After all, you can never travel back in time to do it over again.

Tomorrow, a special technique you can use when you have to shoot a subject in the bright sun.

Manual or TTL?

When making flash pictures, your camera will be on manual mode—I hope so, anyway. It’s the way to go. This means you set ISO, aperture and shutter yourself.

But your flash does not need to be on manual. That is to say, flash power can still be metered and be adjusted by the camera, automatically. We call this “TTL” (Through The Lens metering). And TTL can work even when the camera itself is on manual.

When your flash is in TTL mode, the back looks something like this:

You see TTL, ETTL, TTL-BL, i.e. something containing the letters TTL. This means the flash power is adjusted automatically by the camera. If you are close to something, the flash will fire at low power; if you are far away, a high power flash will be emitted. Magic!

The alternative is that you set the flash power. Manual flash, in other words. Press the MODE button on the back of the flash and set it to Manual:

In the photo above, the flash is set to half power (1/2). It could also be set to full power (100%, or 1/1), or to quarter power (1/4), or one eight power (1/8), one sixteenth (1/16), and so on; or to some level in between.

Try this now. Set your camera to manual mode, 1/40 second, 400 ISO, f/4. Now turn on your flash and set it to manual, and set it to 1/64 power. Using the viewfinder, take a photo. Check the photo: You will probably be hard pressed to see the flash, especially if your subject is far away.

Now set it to full power (1/1, or 100%). Do the same again. Whew, probably a grossly overexposed picture!

But you probably noticed something else. You did not see the flash through the viewfinder. “Did it work?”, you may well have asked. That is because when the flash is on manual, it fires just once, at the power level you set. You do not get the metering pre-flash that it uses when set to TTL mode (a flash at 1/32 power that is used to determine the needed power level). And that preflash is the one you can see through the viewfinder. The actual flash you cannot see!

Now, an exercise.

  1. Find an object to photograph. With the camera set as before, and the flash on MANUAL, find the correct power level for a good picture. Aim the flash straight ahead for this exercise.
  2. Now move 40% farther from the object. E.g. if your original distance was one metre, make it 1.4 metres. Or if you were 4 feet away, make it 5 feet 7 inches (that is 40% farther than 4 feet).
  3. Now find the correct power level for this picture. How much more power did you need? And (an advanced question for mathematicians): why? (Hint: it’s actually 41.4% farther).

Have fun.

 

Starting With Greys

Greeting from The Netherlands, where my teaching tour continues Saturday. But for you, a note about photo post-processing, and about a popular technique, today.

The thought behind this technique is that the “blacks” in your picture do not necessarily have to be black; sometimes a little lighter is OK; the resulting “matte” look can be good.

Look at this image and the accompanying Lightroom “Develop” settings in the “Basic” pane:

Now the treated version: where I made the blacks “not quite black”. The Basic pane looks like this now: look at the “Blacks” slider:

And as you see, the histogram no longer starts on the very left.

The very left of the histogram represents “pure black”; dragging “blacks” to the right makes the start point of the photo (the darkest areas) not “pure black”, but “slightly grey”. This leads to a matte paper type look:

The difference is subtle but clear, once you look at both side by side, or in succession—try.

And as said, this “matte paper” look is very popular among photographers now. I am not sure I am quite as enthusiastic, but hey, never too old to learn.
