Making a Photograph – The Four Pillars

May 20th, 2012
lg share en Making a Photograph   The Four Pillars

I’ve been giving a lot of thought recently to what goes in to making a great landscape photograph. It turns out there are four things, four pillars if you will.  Four, that’s a good number.  There are the four legs of a table or the four wheels of a car.  And not to forget the four sacred directions of the Native Americans.

In landscape photography the four pillars are evenly divided between the aesthetics and the technical.  So what are they?  The two aesthetic pillars are Fantastic Light and Strong Composition.  No surprise there.  The two technical pillars are Appropriate Sharpness and Optimum Exposure.  No surprise there either.  If just one of those pillars is missing, well, the table collapses, the image suffers.

Let’s look at them one by one….

Shoot Till You Can’t Shoot Any More

December 6th, 2008

There’s a lot of talk amongst photographers about shooting in the golden hours – around sunrise and sunset.  There’s no disagreement that the light is wonderful at those times of the day.  The low angle gives excitingly long shadows and the fact that the sunlight has to travel through more of our atmosphere means it’s a bit softer and a lot warmer.

So you often find a lot of photographers lining up for sunset shoots at iconic locations.  The bridge over the Virgin River in Zion is a perfect example.  I’ve got to admit, I love to shoot sunsets from the bridge myself.  Most photographers will arrive early and stay about 20 minutes after the sun disappears below the horizon at which time the pack up and head off to dinner.

I like to stay till I can’t shoot any more.  The light show isn’t over by any means when the glow on the clouds fades.  It’s just a lot more subtle.  As the light fades exposure times increase and when you get up to 30 seconds then ISO starts to bump up.

Why do I like this light so much?  Well, because there is so much going on.  Many complex and intricate things are going on in the sky above.  You end up getting a delicate play of warm and cool light.  Everything is enveloped in a quiet, soft luminance.  It can be a magic unlike any other time of day.

I was shooting on that famous bridge in Zion back in November.  If it hadn’t been for my two friends shooting with me I would have been the only one on the bridge.  Everyone else had long gone.  I was shooting HDR, 5 bracketed shots, something I’ve found to be very effective (don’t forget, the sky stays bright long after the sun disappears).  Each shot was varied by 1 1/3 stop.  Post processing consisted of Photomatix and a little Light Room.  Here’s what I got.  (You can click on these images to enlarge them.)

Watchman at Twilight

A few weeks before I took this Zion twilight shot I found myself in Death Valley on the Mesquite Flats Dunes, again at sunset.  I set up on this one composition and shot it for about an hour and a half.  Many people like the stark contrast created by the sun playing on the undulating surfaces of the dunes.  I like it too.

 But a while later comes the real show, at least for my money.  The play of colors becomes outrageous with reds, magentas, purples, oranges, yellows and blues.  And I love the forms and textures of the sand.  It’s truly amazing.

So for my money, you’ll see me out there (usually by myself) until I can’t shoot any more.  Hey, why don’t you join me and see for yourself.

Then and only then I’ll pack up my gear and head off for dinner.

Note:  All of the above photographs are HDR, not just Zion.

High Dynamic Range Processing

November 29th, 2008
lg share en High Dynamic Range Processing

High Dynamic Range or HDR has become a standard and often used tool when I’m in the field.  For example, a few weeks ago when I was shooting sunrises in Bryce Canyon we would arrive well before sunrise.  Generally I would start shooting when it was light enough to get a good exposure at 30 second, ISO 100 and f/16.  That’s a good 20 to 30 minutes before the sun peeks over the horizon.  In that wonderful pre-sunrise light the dynamic range is very low, maybe a total of four or five stops.  There is no need for HDR because under those circumstances I can get a good 8 and if I want 9 stops of dynamic range from my sensor.

But as soon as the sun is above the horizon all that changes.  The dynamic range jumps to at least 8 stops, probably more.  (I don’t take the time to scintifically measure the dynamic range because things happen so fast in those first few minutes.)  I don’t want to take any chances with that incredible light so I switch to HDR, just for insurance if nothing else.
