@Blue-Eyed Monkey:

Part A: It is hard to evaluate telephoto compression when there is only one object in focus. I also noted that you changed from f8 on the first shot to f22 on the second. The subject and some background must be in focus to be able to evaluate this portion of the assignment. Please try this part again.

Part B: The 24mm backed-out to 50mm is fine. The aspect ratio for the 210mm and up-close 50mm are not close enough and the 210mm is OOF. You may need to increase the f-value for the 210mm shot and make sure that you can reproduce the aspect ratio with the 50mm without running into the minimum focus distance. Think about using 100mm rather than 210mm if this is a problem.

Part C: I'll give you a pass on Part C. You certainly moved quite a ways to your left to get the second shot. Normally, we expect a more subtle shift in camera position, but you captured the spirit of the assignment.

Cheers... Brian

Another attempt at Part A of this assignment. I still need to retry Part B but I haven't been happy with my tries so far!

@Blue-Eyed Monkey: That works for Part A, Glen. On to Part B

Cheers... Brian

P.S. The second could use a bit of noise reduction.

Thanks once again Brian. I've retried Part B of the assignment and although I only needed the close-up part of it, I thought I might as well retry the whole!

Part B. "Zoom with your Feet"
Original scene with normal lens

Taken with Minolta 50mm F1.7 @ 1/160s f/11 ISO200 50mm

Telephoto lens

Taken with beercan @ 1/80s f/11 ISO200 210mm

Normal lens close up

Taken with Minolta 50mm F1.7 @ 1/50s f/11 ISO200 50mm

Wide Angle lens

Taken with Sigma 18-50 F2.8 @1/500s f/11 ISO200 18mm

Normal Lens further away

Taken with Minolta 50mm F1.7 @ 1/80s f/11 ISO200 50mm

I'm not sure if the wide angle and normal lens further away is what you are looking for. At first, I didn't see the learning objective of this part of the assignment but having undertaken it I think I understand that it is about how different focal lengths and positions produce different results. It is therefore about choosing the correct focal length and moving rather simply zooming in or out.

@Blue-Eyed Monkey: Hi, Glen. I'm having trouble understanding the "No. 1 Smithery" in the last shot. It does not appear in any of the other shots. Any explanation?

Thanks... Brian

Where I was closer to the subject it was hidden from view until I stepped back and changed my perspective. The glass structure is about 5m long and the Smithery sign is approximately another 10m beyond that so when I stepped back to photograph the subject my whole field of view altered.

Having had another look back at the task and clk230 on page 7, I've decided that the subject has to be flat or at least narrow for it to work. Apologies for bombarding you but I think that this attempt is probably more what you are looking for than the last effort!



Scene at 50mm

1/250s f/10 ISO400 50mm

Scene with telephoto

1/30s f/10 ISO400 200mm

Zoomed in with 50mm

1/100s f/10 ISO400 50mm

Scene with wide angle
