Frame inside a Frame

Why Photographers use Frame Inside of a Frame - 

They use Frame Inside of a Frame because it basically draws the attention of the viewer to the subject inside of the frame. 

Examples 

I like this picture because it is literally using a frame to capture an image inside of another photo.  

I like this one because instead of a simple frame, the spiral stairs make it look like there are many more frames inside of the photos frame.  This one would look really cool if there was a subject at the bottom of the stairs.  

This is another example of multiple frames but this one was cool because of the two window frames and there is a subject that completes the photo.

I like this one because it uses both reflection and frame inside of a frame.  This is a cool picture of a reflection that is framing a bridge. 

I like this photo because it uses a shadow frame and it also looks like the subject is a shadow aswell which is pretty nice.

Me 

I like this photo because it is a very wide frame, the subjects are both almost completely centered and it depicts everyday life. 

This is a corn hole board used as a circular frame, this one looks really nice because of the good line up with the dock and the background is very nice ( goes well with the shot). 

I thought this frame was pretty cool,  you can kind of see the subject in the background sitting down and it really depicts Frame inside of a Frame. 

While we were walking around I turned to wait for my partners and one of them scratched his head and this is what I saw as soon as he did it.  I knew I had to get the shot because it was a very creative and it fit the criteria very well.  

This is also one of my favorite photos using the lid of a trashcan.  It worked out because the trashcan lid was rectangular and the dimmed background makes the inside of the frame really pop which was cool. 

I like this one because again its a shot of everyday life and i angled myself so the structure under the stairs lined up with these two doing homework.  

I like this photo because I thought it looked like I took a photo of a picture of the MANS building and it just looks really clean. 

I liked this one because we used a two sailing masts and lined them up with a railing to create a frame that looks like a portrait of the subject.

This was also a creative one, I do not know if it completely fits the criteria but I used a cone to take a good looking photo of a bridge, this one also looks pretty clean. 

I like this photo because it was hard to shoot, the ring was very small, but i think it came out great.  I wish I could have zoomed out a little more to get more of the ring in it but it was super hard to keep the focus.
