Happy Holidays! Mmmm, smell that cinnamon and pine.

My first attempts at an HDR shot using studio lighting. I used a 4-shot bracket (+/- 10 units – approx. 20-50) to create an HDR image.

Photographed with a Canon EOS 5D and Canon EF 100mm f/2.8 USM Macro Lens. Exposure of ISO 500, f/13.0 for 1/60 with varying strengths of light output. Lit with a single soft box on 300 W/S monolight and a white semi-circular reflector.

Processed in Photomatix Pro 3.2 with post-processing in Adobe Lightroom 2.5 and Photoshop CS3.

How I got this shot

I love my 35mm f/1.8 prime lens. No, it doesn’t zoom–I use my legs for that–but it does give me some great bokeh.

For this shot, I placed the stuffed snowman on the floor. I then placed myself on the floor, so that I was at the same level–actually, looking up at the snowman. I then adjusted my aperture from 1.8 to 2.0, as I’ve read many articles that suggest you get a sharper shot when you step down from your camera’s maximum aperture.

I took a few test shots and made the following adjustments. I increased my ISO to the point that I could get enough light while still hand-holding the camera. You can see that I ended up at an ISO of 1000 and an exposure time of 1/20 second. Any higher ISO and I risked too much noise in the pic. Any slower shutter and I risked not being able to hold my camera still enough to avoid blurring.

Lastly, I positioned the snowman about 6 feet from the Christmas tree. The combined aperture and depth of field gave me that pretty “bokeh” effect on the lights. They were out of focus and hence, you get that flared look.

Processing

Not much processing in Apple’s Aperture software. I boosted the vibrancy and contrast a little, but not much else. The only other thing I did was to clone one of the lights and paste it twice on the right of the picture. I did this because I realized that I had a small black area with no lights. To keep the image balanced, I added these lights. That’s about as sophisticated as I get with “photoshop” (although I actually used Aperture’s clone feature).

Camera: Canon EOS 20D
Exposure: 0.017 sec (1/60)
Aperture: f/5.6
Focal Length: 55 mm
ISO Speed: 400
Exposure Bias: 0/2 EV
Flash: Flash fired, auto mode, red-eye reduction

I wanted to test selective focusing to achieve a very shallow depth of field–also known as bokeh. Even though the largest aperture I could achieve was f/5.6, by using a zoom lens at 55mm, I was still able to get that bokeh effect.

I was actually trying to focus on the tip of the snowflake, but ended up focusing on the center. I ended up liking this shot regardless–and liked the out of focus at the front and back.

I added a little flash to make the snowflake sparkle.

The image was captured in JPEG with no post processing or enhancements.
