Selecting the right depth of field for photos is one of the constant topics being discussed. I have here one examples of same scene with 2 extreme full settings, one taken with F2.8 and other with F32. I tend to prefer the one with less depth of field (taken wth F2.8).
Photo is taken with Canon EOS 5d Mark II and EF 100mm f/2.8L Macro IS USM.
I this experiment I was trying to study how much polarizing filter does impact reflection on the water. These 2 images are taken seconds from each other, both with circular polarizer attached but I turned the filter between the shots. Results seems to be quite clear here.
In this first one you can clearly see thru the water. Effect of polarizer is used to reduce the reflection as much as possible. And in the second one only reflections are visible:
Some very usefull tips in the link above.
One good use for HDR photography and processing is to create fairy tale -effect. With these example images I was not trying to hide the fact that they are HDR, instead I went slight over the top.
All these 3 HDR’s are made from 3 raw files, taken with Canon 40D without tripod. 40D has such a good fps rate, that I have had reasonable results without tripod. Trick is to have 40D on fast burst mode, and have exposure bracketing on, and just try to keep camera as steady as possible while shooting the sequence of 3 shots. On most situation software, eg. Photomatix in this case, is able to cope with small movement between the shots.
I have tried to create HDR like effect by 3 simple adjustments to original image. Adjustments made were:
- Decreasing exposure by -0.5 full stops
- Lightening the shadows by 31 units
- Increasing image temperature by 1500 degrees (well, not needed for HDR effect, but was appropriate here otherwise)
