I just got my first DSLR, Nikon D5200 and after reading various tutorials and understanding basics of Exposure Triangle, I was out for testing my knowledge to get a practical view of how things get different with different settings.
Now that I'm back, I'm stuck in a odd situation.
Please have a look at http://imgur.com/a/1Eu85. All the 4 pictures have 18mm focal length and are shot in Aperture Priority mode.
Here's the EXIF data of the 4 pictures (all at ISO 100):
- 1st : f22, 1/60
- 2nd : f14, 1/200
- 3rd : f9, 1/500
- 4th : f 3.5, 1/3200
The odd situation is, in small aperture (large f number) the exposure is bright while in large aperture (small f number) the exposure is underexposed. How can it be so?
Technically I thought all the pics should have the same exposure, as in A mode, camera changes the shutter speed along with change of aperture to maintain a balanced exposure. And, as you can see it did change the shutter speed to maintain the ratio.
How did this happen?
