Another flash tip for you today.

580ex2 Flash

Say you are using a flash for a portrait outdoors. You want to decrease the ambient light, of course, and add flash to light your subject. But uh oh – you run out of enough power. You verify this with the full-power tip I gave you the other day. Not enough.

Now what?

One option: concentrate the light more.

Your flash includes a zoom mechanism, to ensure the light goes as wide of the lens. If you have insufficient power, you can:

  1. go to manual flash zoom (press buttons on the back of the flash for this)
  2. zoom in to a longer setting then your lens (e.g. 100mm when in fact you are using a 35mm lens).

Drawback: only the centre of where the flash aims is now lit – so, aim carefully. The big benefit, however: the light is concentrated more, and hence brighter. You get more power when you need it!

I am off to Vegas now, to teach Advanced Flash with David Honl. Talk to you all soon!

DSLR or point-and-shoot?

People often ask me: should I get a DSLR or a point-and-shoot?

Of course there is no answer to that that I can give – any more than to a question like “should I buy a Kia or a Mercedes?”. But what I can do is give you pros and cons. So you can decide for yourself.

First, there is the simple point-and-shoot. These are small, simple, light. They have few buttons. These cameras are truly “point and shoot” – except this is perhaps an oversimplification.

Point-and-shoot

Point-and-shoot

Pro:

  • Small, light, quiet. You can put one in your coat pocket and forget it.
  • Affordable.
  • Simple macro mode.
  • Simple scene modes (“food”, “party”, etc) for people who do not know photography.

Con:

  • Confusing menus
  • Most functions accessible only through these menus
  • Easy to hit the wrong button accidentally
  • “Noisy” – in the sense that high ISO pictures have grain
  • Slow to react after you press the button
  • Often, no viewfinder, meaning impossible to see in bright daylight
  • No ability to achieve limited depth of field

The simple point-and-shoot is for light, casual users who do not demand much from their cameras. If a simple occasional snapshot is what you want, go for it. Else, look at the next categories.

Next: the advanced point-and-shoot. This category includes the Canon G11, the micro four-thirds cameras, other fixed-lens “pro-sumer models”, and most Leicas, for example.

Pro:

  • Almost as small as a simple point-and-shoot
  • Other advantages too (quiet, light, etc)
  • Much better functionality: more “DSLR-like”.
  • Including all the professional modes: P, A/Av, S/Tv, M
  • Better user interfaces
  • Lower noise (digitally speaking), making slightly higher ISOs possible
  • Often, a viewfinder – albeit small, it’s often there.
  • More buttons. (Yes – this makes it easier!)
  • Can take an external flash
  • Some, like the micro four-thirds cameras, can even take additional lenses.

Con:

  • Still “not quite a DSLR”: higher noise than DSLR, slower focus, slower reaction speed.
  • No interchangeable lenses for many of these
  • Less ability to achieve limited depth of field

This category is great for people who want pro-quality photos, or nearly so, without the bulk. Yes, there are compromises, but these are minor compared to the alternatives. I would carry one of these if I could not carry a DSLR.

Finally, there is the DSLR. From low-end (Digital Rebel, D3000/5000) to medium (7D, D700) and all the way up to high-end (1D MkIV, D3S), these are the “gold standard”.

Pro:

  • Great quality, low noise at high ISO
  • Fast focus
  • Fast repeated shooting, so you can shoot sports
  • Immediate shooting: press the button, get the shot
  • GREAT ability to achieve limited depth of field

Con:

  • Heavy, bulky
  • Costly
  • Need to change lenses for different purposes
  • Need to learn some things.

I called this the Gold Standard – because it is. There is a reason all the pros use these. There is often no way to get the shot you want without them.

My advice is to start with an SLR. If that is not possible, go down to one of the other categories. Even the cheapest SLR will produce professional pictures: no need to spend $5,000 on a camera unless you need the specific features this brings, such as ultra-fast operation, the ability to use dual memory cards, or waterproofing.

Flash tip

Today, a quick but important (and as far as I can tell, pretty unique) TTL flash tip.

So you want to know if you can do a certain shot? TTL outdoors is fighting against the sun. Do you have enough power to do the shot? It’s always a battle.

You can of course fire a test shot. If the flashed area is dark, try exposure compensation, maybe. Or spot metering, or using FEL (flash lock). Or rely on the LCD display on your flash to tell you the expected distance. All very time consuming and uncertain. What if I just want to know “do I have enough power in my flash to do this shot” and then if yes, figure it out from there?

I am glad you asked.

  1. Set your camera to highlight review mode (“blinkies” on)
  2. Set your flash to MANUAL
  3. Set power on the flash to FULL (100%, a.k.a. 1/1)
  4. Take the shot!

Now you know:

  • Blinkies means yes, you have enough power. Turn the flash back to TTL and go from there.
  • No blinkies means that however you compensate or meter, nothing you can do. Get closer, or increase your ISO, and try again.

Simple, innit? This trick has saved me countless times.

Tricks like this one, and many more, is what you will learn in Las Vegas next week, and in Mono, Ontario the week after. Come join me and David Honl in Vegas and me and Jospeh Marranca in Mono to learn more!

Manual focus? Six reasons.

Should you ever focus manually? When?

Well, yes. Indeed there are circumstances where manual focus (setting lens or camera switch to manual focus, and turning the focus ring yourself) is the way to go.

And here’s a few of those circumstances. I can think of six right away:

  1. Macro. When shooting macro, for instance when shooting flowers, bugs, food or jewelry, use live view and zoom in electronically if you can, then use manual focus.
  2. You are using a Nikon D40/60/3000/5000 and a fast 50mm lens. Those lenses do not autofocus on those low-end Nikon cameras, so you have to do it by hand.
  3. It is night. Your camera cannot focus well in the dark.
  4. When shooting through glass, like on an airplane.
  5. The subject has low contrast. Ditto – you may have to do it by hand.
  6. When the subject is unpredictable in time but not in space – like fireworks. Or sports, when you know where the action will be. Pre-focus there manually!

Tip: Do not confuse manual focus with “using one focus point”. When using autofocus, you should always (or virtually always) use one focus point. When the camera chooses it will choose what you do not want to see sharp.

Homework: go take ten pictures right now where you focus manually. You;ll see how easy it is, and how consistent once you get it right.

Today

…during the Netherlands-Uruguay game.

Tech Note: In a bright room like that, straight flash (aimed forward) is an option, but as fill – meaning I expose just under for the ambient light and Flash Exposure Compensation is set to -2 stops.

Enlarging the moon

One aspect of wide versus telephoto lenses is how large the background gets. As in “If you want a large moon, use a long lens”.

Huh? What do you mean, Michael?

I shall illustrate with a couple of shots I took of a student during a “Creative Urban Photography” outing the other day. One with a long lens, and one with a wide angle lens.

Ignore the light (I was using a flash with a warming gel on one camera, and no flash at all on the other), and look instead at the size of the blurred-out car in the background:

Here’s picture one:

Now look at picture two (where by moving my position I have kept the subject the same size):

See how that car magically grew much larger in the second picture?

Do I need to explain which picture was taken with a wide angle lens, and which one with a telephoto lens?

So now imagine the person is a tree and the car is the moon at night, or the setting sun. So what lens would I be most likely to use if I want a large moon or a large setting sun?

Nifty Fifty

Everyone should own a fast 50mm lens, I keep saying. “Fast” meaning a prime, large aperture lens (like a 50mm f/1.8, or even a 50mm f/1.4, like this one:)

One student asks a good question about this:

“I recently attended your travel photography and Nikon Pt. 2 classes. You spoke about the value of a 50 mm lens. I have a Nikon D90, which is not full frame therefore I am wondering if you still recommend the 50 mm over a 35 mm.”

Good question.

As you know, a small sensor camera (like most of today’s DSLRs) appears to “lengthen” the lens (search this blog for “crop factor” to see why). So a 50mm lens will work like a “real” 80mm lens.

In “real” terms,

  • 50mm is a “standard” lens;
  • 80mm is a great portrait lens for half-length portraits and headshots.

So presumably we should all start with a “real” 50mm lens? On a regular (non-“full frame”) DSLR, that means you need to buy a 35mm lens.

So is my advice really “buy a lens marked 35mm” or “buy a lens marked 50mm”?

Ideally, both. But if you have to choose, start with the 50, because:

  • You’ll want to do headshots sooner or later;
  • Sometimes you’ll use it for product or detail-shots, too;
  • Above all: it is very affordable.

Most manufacturers make a 50mm f/1.8 that costs around $150 or less.  A bargain, and something you just need to put in your camera bag.

July 4 fireworks tip

Quick recipe for fireworks, US friends!

Fireworks, by Michael Willems

Technical tips:

  • Mode: Bulb, with remote release
  • ISO: 100
  • Aperture: f/8 – f/11
  • Shutter: 1 to 30 sec; usually 2-5 seconds
  • Focus mode: Manual, prefocused “where it will happen”
  • Shutter mode: One shot
  • Camera mount: Tripod (this is mandatory!)

And the usage tips:

  • Set up your camera on a tripod, and aim at the fireworks source
  • Avoid being downwind (the smoke will ruin some of your pictures).
  • Manually pre-focus where the fireworks will go up (or on “infinity”).
  • Use wire/radio release, so you do not need to touch the camera.
  • Start when a particular firework goes up, and hold the shutter open until that one  is done (but avoid getting the next one in the picture, unless it is aimed differently). This will usually take 2-5 seconds.

And above all, have fun, and happy 4th of July!

Quick flash tip

It is July 4 in the US, so my American friends will all be taking pictures today. So here is a quick tip for you flash users out there!

If you want a slightly warmer look – the “late afternoon light” look – to your flash pictures, simply do this:

  • Put a slight warming gel (e.g. a quarter CTO gel, or a half CTO gel) on your flash (i.e. slightly yellow). I use a Honl gel with a Honl speedstrap on my 580EX flash.
  • Set your white balance to “flash”.

Result: your subject (close by, lit by flash) looks slightly warm.. instant late afternoon “golden hour” light even at noon.
