No worries. I’d like to ensure you understand each assignment before you move onto the next.

In this assignment one of the things that is highlighted is that order to show motion you have to be able to control light. You’re faced with a situation where there is too much light. Hmm what to do!

I’m not going to tell you the exact settings because the exact wrong way to approach learning photography. It’s like that old Chinese proverb:

Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime.

It’s the same thing here, if I just tell you what fstop to shoot at or what shutter speed you won’t learn anything. I want you to understand what settings to use and to choose them.

Here is the EXIF data:

One thing I would recommend right away is to turn your flash off. It appears as though your flash was triggered in all of these photographs when it wasn’t needed.

When you got a white blank screen that means there is far too much light and your whole image is completely blown out. Way way way too much light.

In your photographs of the waves you have shown motion but you’ve noticed this creates a problem. A slow shutter speed and lots of light makes for blown out images. So you have to compensate somehow! You could use neutral density filters, use exposure compensation, shoot at a different time of day with less harsh light etc etc.

The key here is that you start to understand this relationship and start to play with it. It’s not totally obvious but you just need to work on it.

Now for your photograph of the dog and your attempt at shallow depth of field. You’ve done well but you need to understand a few things here. First when shooting something that has very shallow depth of field you have a very small area that is in focus by definition. With that in mind I want you to look at your image age. Notice how the dog’s foot is in focus but the dog’s nose is not in focus.

The lesson being that when you shoot shallow depth of field you want to absolutely nail your focus. And often the little screen on the back of your camera won’t show you unless you zoom right in to check focus.

Click on these photos and you’ll see what I mean:

[attachment=3:2k30h1tt]dog shallow depth of field 2.jpg[/attachment:2k30h1tt]

Now if you look at the whole image at about the size you see it on the back of your camera you’d think it was in focus:

[attachment=2:2k30h1tt]2013 01 31_2019_edited-1 10 percent size.jpg[/attachment:2k30h1tt]

That said you’ve show an image with shallow depth of field and done well on that component of the lesson. Just be sure to nail your focus!

Overall I think there is a great deal to be learned here from these images.

Here are a couple of little cheat sheets for you 馃槈
