Lesson 3 Assignment

[Emily Guzman]

the picture outside is the slow shutter speed and the one inside is the shallow depth of field. the dog in the box is the main focal point. I’m not sure if its correct. i tried many times to get it right, still not sure its what it supposed to be.

Hi Emily,

Thanks for submitting your assignment. It looks like you might be having some trouble here. That’s totally ok!

Maybe if you could answer some questions for me I can get a better idea of where you’re at.

Are you able to full control your camera manually?

Do you understand depth of field?

Do you understand shutter speed?

If you’re having trouble with either of these concepts let me know and we can go from there.

Thanks.

yes i can fully control my camera manually. I’ve been using it manually to try and grasp the concept of every option on the camera. i understand depth of field as how much detail you can get into your picture using the aperture setting. shutter speed is how much light you let into your picture. i may be understanding something wrong or maybe even doing something wrong when trying to get the pictures for the assignment.

It’s great to try and shoot on manual as much as you can! I think one of the things your missing here is ISO. I noticed this because in both images your ISO was set at 1600.

ISO is a fancy way of saying how sensitive your camera is. The higher the number the more sensitive your camera is. Of course that comes with more noise. So in your image of the dog up close you can’t even really see any depth of field because the noise of the image has kind of taken over.

Also be aware that your lens will have a minimum focusing distance. If you get too close to something your lens may be unable to focus on it. This may be the case here as the dog doesn’t appear to be in good focus.

Don’t worry about doing anything wrong, it just takes practice to keep it all in mind.

You had the right idea here with your fstop though. F 2.8 should lead to shallower depth of field all else equal.

Image Description:

In this (outside) picture the shutter speed is 1/1000th of a second. This is actually a relatively fast shutter speed. This is the opposite of what the assignment called for.

I feel like you could use some more work here and you may want to try this assignment again. Don’t worry though, it will all make sense with more practice.

Take a look at this page on the exposure triangle. It might help you refresh some things in your mind.

You just have to work at it!

Keep practicing.
