| p.1 #1 · Aperture issues with portraits-need advice |
Ok ya'll, this is actually my first post here. Anyway, I have a question about aperture. I understand how aperture works but in a practical sense I am having trouble. I have done maternity shoots, newborn shoots, engagements, and basically just general portraiture. I typically don't have any issue when I am using my single point focus point on my Mark III and around a 2.0 aperture.
However, sometimes my pictures come out "soft", and I don't really know it is happening until I get them back and into LR. Some are super tack sharp (like you can see the eyelashes) and some are soft.
I went to a book signing and I took my camera and just wanted the person to be able to "point and shoot" basically (since I was handing my camera off to someone). I set the focus point on auto (that way it would hopefully just focus on what was closest or in the center). It was a dimly lit room so my ISO was at 1250 (as I didn't have my flash with me), shutter 1/80, and aperture at 4.0. The girl taking the shot took two shots and they both looked like this (this is about a 1:1 ratio crop). See how the person in the back, is blurry and the person in the front is not that sharp.
I typically don't shoot pics at a high iso (since usually I shoot in natural light) but I was unsure what happened here. Was it camera shake, is my lens is having issues, is my aperture was too wide? It seems like f/4 is perfect for two people (especially since our faces were pretty close to being on the same plane). You also would think ONE of us would have been in focus. Anyway, maybe someone can help me out here? I end up with this same issue on some of my portraits too.
