I'm sorry I'm bombarding the board with all my posts, but I have such limited time with this borrowed camera! I know I mentioned in my last post that I would be focusing only on exposure, but it's so hard not to jump around!
Any CC would be appreciated! These are SOOC except I did crop a bit.
Exposure: 0.008 sec (1/125)
Focal Length: 22 mm
ISO Speed: 800
I know comp on this is not great, but I was working on trying for bokeh (sp?). I know that in the right is distracting...my herb box! I'm sure I can crop it out.
Exposure: 0.008 sec (1/125)
Focal Length: 45 mm
ISO Speed: 200
I know this isn't the most pleasant to look at...our compost pile, but I wanted to practice DOF (I hope I getting these acronyms right!)
Exposure: 0.008 sec (1/125)
Focal Length: 30 mm
ISO Speed: 100
1) I agree with cloning out the seam. It's a bit distracting. Great capture though! She doesn't look too happy!
2) She's a bit centered, which if you crop out the herb box, I think it'd make a difference. Great bokeh though!
3) interesting, but it doesn't do much for me.
Good for you for practicing as much as you are! It's tons of fun huh?!
#1 looks really nice. You got great catch lights, focus and exposure look really nice too. The seam doesn't bother me, but cloning it out would only enhance the photo, imho.
#2 has some fairly nice bokeh. I'd probably try and open up the ap a bit more, that should only help the effect.
Your DOF could be more noticable in #3 if you opened up your aperture some more. f/7.1 still leaves a bit in focus and the kids are just barely starting to blur here. I think if you dropped it to f/3.2 or so you'd see a much bigger difference.
You're really making great strides in a short time w/ this camera. Hope you're having fun w/ it (it LOOKS like you are).
Thanks! Yeah, the seam on the first drives me nuts, but i noticed when my niece woke up from her nap the other day how nice the light was and so wanted to try it out as soon as she woke up. We're going to move her crib so I can possible use that wall to put my backdrop on! Seems to be decent light coming in!
Aperture is still confusing me. It's just not clicking at all! Anyone have a quick rule of thumb to help me understand?
I so want to do some PP on these, but I figure I only have the camera for a short time and once I give it back I can practice using PS then
Thanks so much ladies! I really appreciate the CC
To *try* to explain the ap- (I understand it in my head, but I have a hard time putting it in words, but I'll try-
The smaller the ap, the more bokeh. So if you are wanting some in particular in focus, and the rest of the backgroud blurred, you want a smaller ap. Have you read this?
Yep, these are great first shots!!! I agree with the seam and #3 to get more DOF. The smaller the ap number, the more bokeh. As you stop down, which is actually making the number bigger, ap smaller, and letting in less light, the wider range of focus. Eh, that's my best attempt at explaining it. I tried to explain after raising my hand to answer the question in my class this summer and couldn't do it then either.

The article link listed by pp is good!
Regarding the practice of depth of field, one of the easiest ways to do this is to open your aperature as much as you can (smaller f-number) and space three objects on your kitchen or dining room table. put one at the edge of the table closest to you. put the second in the middle of the table, and the third at the edge of the table farthest from you. Don't put them in a straight line...stagger them a bit from one another. put yourself in a position as close as you can to the first object and still have the other two objects in your frame. Put the lens on manual and turn the focus ring until the first object is in focus. Take a photo. Without moving, change the focus ring until the second object is in focus, and take another photo. Do the same for the third object. Then double your aperature setting (if you started at f4, continue to f8, and then f16) and repeat the exercise two more times. Then compare all the photos. This will give you a pretty good grasp on depth of field. And it doesn't HAVE to be objects on a table...they just tend to be the most cooperative (lol). You could also say for instance, place chairs in the yard, or even have the kiddos stand a fair distance apart.
Basically, the smaller the number, the larger the opening. There are two things changing the aperature affect...the amount of light let into the lens, and the depth of field, or the length of the area that will be in focus.
When it comes to the amount of light let in, the smaller the f-number (or the larger the opening), the faster your shutter speed will be able to be. It's good to know if you're shooting in a low light situation. This is part of the reason some people call their 50mm lens the "nifty fifty"...most of them allow for a large enough aperature that you can take good photographs even in lower light settings.
As far as depth of field, think of it as the distance between the sharpest point of focus closest to you, and the distance between that and the sharpest point of focus farthest away from you. For most portrait and child photography, I usually stick to a pretty low f-stop because I want there to be a dramatic difference between the focus on my subject and the background behind my subject...and in some cases this distance is only a few feet. This is where you hear people talk about "bokeh"...the out of focus points of light behind your subject. A shorter depth of field allows more "bokeh". This is also another reason for the name, "nifty fifty" because the short depth of field allows for nice bokeh with most lenses. You would use a smaller aperature, or higher f-number, when shooting landscapes, for instance, when you want both the foreground and the background to be in equal focus.
I almost always shoot in aperature priority mode, meaning I select my aperature size, and the camera selects the rest of the settings. I always override my ISO settings and keep them at 100, so basically the only thing the camera controls is the shutter speed. This is because I usually want the most control over my depth of field.
