So first, here's the photo I would use if I were just posting one and not experimenting:
|f1.8 -- 1/1000s -- ISO:400|
(Accomplished while two biggest were proofreading their writing work, two middles were plopped in front of Olivia and tiniest was snoozing peacefully in ye olde baby cage. Imagine me attired in a black raincoat, sneaking out the front gate and crouching under a tree on the side of the road, using my torso to shield precious toy from the rain. Anything for my art! Not really. Anything to not do chores is more like it.)
Then I decided to do some experimenting. See, I like to use a low f-stop number which actually means a large aperture. NB: Camera people invented this way of discussing these things in order to confound and confuse normal folk like me, I swear. But I persevere! Anyway, f1.8 is the smallest/largest aperture I got and that's what I used up there. But what changes on a close up shots like these when I change the aperture? Let's find out:
|f1.8 -- shutter speed 1/4000s -- ISO 400|
|f3.5 --- 1/1000s -- ISO 400|
|f5.6 -- 1/400s -- ISO 400|
|f8.0 -- 1/500s -- ISO 800|
|f16 -- 1/200s -- ISO1600|
So what have we learned? Well, I don't know about you guys, but I kind of can't tell the difference between a lot of these. The first one has such a shallow depth of field that only a portion of the leaf manages to be in focus. That may have also been user error, bee tee dub. But all the other ones just kind of look the same to me. So for me the moral of this particular story is that I don't really need to use my 50mm lens when taking close up shots with no distant background. The kit lens, which goes down/up to f3.5 should be totally fine for this kind of stuff.
Note though that I had to increase ISO and decrease shutter speed as the f stop number got bigger because the camera is letting in less and less light. If your subject is moving or you don't have steady hands or it's super gloomy or you're indoors, the low f stop number will help you be able to use a lower ISO (better image quality) and faster shutter speed (less chance of blur). So there's that.
Okay, hope that was helpful if there is anyone reading this who has a big girl camera but who knows less about big girl cameras than I do, which I doubt.
