Q and A: How to handle color balance?

Jay and I get lots of emails from other photographers - and we try to respond to all of them (though that's not always easy... and it's getting harder every month). Today, I answered an interesting question - and I thought some of you might also be interested in the answer... so here it is.

S asked: "In several landscape photos - most of which are taken during sunrise and in coastal areas - I see that the foreground water has a cool blue tone, and the sunrise has a strong warm tone. When I try this for myself, I either get one of the cool or warm tones, or get a mix of both. How this blend of cool and warm tones is achieved?"

My response: In wide-angle nature photography, it is very common to have an image that requires different white balance in different regions. In order to handle situations like these, I shoot RAW and process a single images at least twice – once using warmer tones, and then again using cooler tones. I open both versions of the image in Photoshop, and use layers and masks to combine them - creating a final image that is as close to my visual reality as I can bring it.

In the real world, it is rare to find a scene with even light balance overall. Shady areas have a different light temperature than sunny areas, reflected light is different from diffused light, and so on. It is up to the photographer to determine the nearest reasonable color balance for the best possible result. I try to create a final image that is as close as possible to reality as I saw it. It’s not always easy – and my images aren’t always perfect – but I do try. :)

Wildflowers

I spent more time shooting with my new 180mm macro than with my wide angle lens on this trip. The Smoky Mountains are beautiful, and we did get some nice evening and morning shots - but we spent some time during the day searching out wildflowers for macro photography. We were there at exactly the right time. Trillium grows everywhere at the lower altitudes - white, pink, and yellow varieties. We also found Columbine, Buttercups, Irises, and a thousand flowers I can't name. That's Wild Columbine (aquilegia canadensis) on the right and Yellow Trillium (trillium luyeum) below.
I could have been perfectly happy to spend another week wandering through the woods. :)

The trick with shooting flowers is to find an angle that allows you to capture the flower with green leaves in the background. Most of the time, the flowers are pretty close to the ground, so unless you are shooting from above, you need to get very close to the ground. Use a tripod that can go as low as possible, and lie down if you need to. Don't mind the bugs - as my mother always said... "They're more afraid of you than you are of them." (Of course, all bets are off if the bug has eight legs.)

A shallow depth of field blurs the background, and lets the flower stand out. The center of the flower should be in perfect focus - that's not as easy as you think. :) Shoot on a windless day if possible - or wait for a calm moment. You'll likely need to increase your ISO to reduce your shutter speed as much as possible... but remember that with a high ISO, you'll get more noise, so try not to go too high. Use a translucent filter (or a sheet) to soften direct light - or shoot in the shade for soft, even lighting. Overcast days are perfect for flower photography.

Try to keep distracting elements out of the frame - the eye goes to the brightest spot in an image, so make sure the brightest spot is your flower.

Jay and I will be presenting at the Akron Camera Club on Wednesday this week. We are putting the finishing touches on the presentation today. It should be fun!
