I've found one suggestion about taking photo of sky:
The sky becomes white in ur photos unlike others who retain blue color?? - Stop down the aperture to f8 or more, decrease ISO to 100 and slower down the shutter speed to anything near 1/80th of a second.
The sensor in DSLR absorbs different spectrum of light at different rate. Blue is slowest. So you need to find ways to slower the shutter speed to a point in which lots of blue can be exposed on sensor..
When I try to do some landscape photo, I often got overexposed sky, so it has a couple of huge white blocks. I thought that the problem is in too much difference between needed light for sky and ground. As I know that could be fixed by:
- HDR photo
- Graduated filter
But does this suggestion have sense at all? Does it helps in better landscape photo exposure?
