This photo is an alarm bell on the wall, E&P are color and shape.

I took this photos for over 10 times, and I choose this one because this one is the best one of them, and I decided to adjust the color. It looks better than first. I learned how to adjust the exposure and ISO. The challenge was adjusted the photo in Photoshop.

This photo is about a keyboard, I had no idea that what to take, so when I come back from outside, I saw my keyboard, so I just take a photo of my keyboard. The E&P are lines and value. some of letters are clear and some are not, I think that is kind of depth of field, and the challenge is to focus on the keyboard, I tried for a long time.

This photo is a footprint on the snow ground, I don’t know the E&P is shape. This phot is simple, just a footprint and I didn’t do any adjustment.
