Depth of Field & a Rainy Day!

Hello Friends!
Today I was planning on spending my morning outside in the sunshine taking pictures and working on some of my photography class assignments.  It's a dreary (but much needed) rainy day!  I actually really LOVE rainy days but I have only learned how to take outdoor pictures so far in my class with real natural light!  YIKES!  What is a girl to do???  Well, I decided to make some lemonade and get out there anyway!
Today I am still working on my Aperture assignment but wanted to mess around with the depth of field, too.  Here is a detailed description for all of you who do not know what Depth of Field means...

"In optics, particularly as it relates to film and photography, depth of field (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a lens can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions.
In some cases, it may be desirable to have the entire image sharp, and a large DOF is appropriate. In other cases, a small DOF may be more effective, emphasizing the subject while de-emphasizing the foreground and background. In cinematography, a large DOF is often called deep focus, and a small DOF is often called shallow focus.
The DOF is determined by the camera-to-subject distance, the lens focal length, the lens f-number, and the format size or circle of confusion criterion."

So what I've done on this first set of pictures is set my dial to Aperture Mode (which is A on a Nikon) and I used the front dial on the right side to set my Aperture to 1:1.4.  If you have a kit lens or you are using a zoom lens it will be a higher number.  I splurged and purchased the 50mm 1:1.4 lens for my Nikon and am soooo happy that I did!  My indoor shots are so much brighter.  The reason is that my Aperture goes open all the way to 1:1.4, which means it brings in more light.
For my depth of field test I just took the same focal point but I moved closer and farther away.  I kept my Aperture on 1:1.4 the entire time.  LIke I said, it is a rainy day so these would look so much better with the sunshine.  :)

Week 2 - Day 2 (Apertures)

It's so much funner having a live model for this assignment!

Aperture Speed 1:1.4

Aperture Speed 1:13

Open Aperture 1:1.4 (notice how the subject is sharp but the background is blurry?)

Closed Aperture 1:14 (notice how the background is sharp along with the subject?)


Week 2 - Apertures

Hello Everyone!

This week I am learning all about how to use my Apertures.  I also just got my new Nikkor 50 MM 1:1.4 lens in and am LOVING it!!!

I am taking the Oh Shoot! class at Jessicasprague.com.

I'm using an open aperture on this one of 1:1.4.  What that does is focus on one image and blurs out the rest.

This one is with a more closed aperture.  I used 1:14 Aperture.

This is also an open aperture of 1:1.8.

 What I've also noticed with the closed aperture is that it does make the picture a little darker which is nice for full sunlight but probably not so great for indoors.
