Second attempt at the dice macro.
Same 'basic' composition, with the following changes. I brought the ISO down to 200 and let the shutter speed come up to 1.3s to compensate. The colour of dice is obviously different as well, which really helps the contrast, I think. Lighting was improved, and the white balance is better. Less clutter in the frame as well. I tried to position the camera to let the woodgrain stand out more as well.
The obvious problem is the reflection on the table surface. They are minor, but I should have diffused the light better. The shadow on the die at the front is quite harsh as well. Bokeh is pretty chunky, but I'm not sure how to adjust that unless I use a different lens?
