Over in the How I took it section of the DPS forums murtasma has posted a HDR image of a lizard’s eye and has given a description of how it was taken. I hope you enjoy reading about the process.
- Camera: Canon Digital Rebel XTi
- Exposure: 0.01 sec (1/100)
- Aperture: f/5.6
- Focal Length: 51 mm
- ISO Speed: 800
Taking the Shot
I used the kit lens that comes with the Rebel XTi. I attached a generic close up lens of cheap quality so I could obtain a closer macro image of my leopard gecko’s eyes. I placed my lizard in a homemade lightbox luckly she didn’t run around much and stood still most of the time. However she did not like to stay in the center of the box so the lighting was not even in many of the pictures I took.
Post Production
I then used photomatrix to create a HDR image from one exposure. I did this becuase the colors were washed out and I wanted to enhance the detail inside the gecko’s eyes.
Once I tone mapped the image in photomatrix and saved as a 16Bit Tiff file I loaded the image into photoshop for editing.
First I adjusted the white point in the image by useing a levels mask. I bumped the white point up a lot then masked off the gecko. I then created another layer mask for the contrast and mask off the white background and the eye since I did not want to affect the eye. I wanted as much detail to remain as possibe since this was going to be the focus for this image.
