@trouty00: You get a pass on Part A, although it would have been nice to see the second image at the same scale as the first.

For Part B, you nailed the walk forward, but it appears that you went back too far back on the 35mm to match the field of view for the 18mm. The boat appears about half again bigger at 18mm than at 35mm and you included a large yellow pole and what appear to be railroad ties in the 35mm shot that did not appear in the 18mm shot.

For Part C, you were right to try to avoid the block building in the background, but you needed to move a bit more to your right (and perhaps back) so as to get the entire foreground structure and lamp in the frame.

I'm going to ask you to try again on the "walk back" section of Part B and try again on Part C (a new second shot at the same location or two new shots).

Cheers... Brian

Thank Brian, I did get a bit confused with part B as dint know if I was supposed to be getting the 'same shot' which I just could not manage to do which I have to admit drove me a little crazy so I shot what i thought and moved on. Through reading through previous posts on this thread I guess the intention is to match the size of subject (the boat in this case) rather than replicate the image. Is this correct? I think I will go back and try again with same subject for the walk back part but think it will be inevitable that the yellow post will show up as i was pretty much in line with it for the 18mm shot


as for Part C I completely misunderstood this one, I thought it was implying only the camera could be moved and I had to be stood still hence I tried to make best of what options I had. Think I will do this one again completely.

as for the sizing, problem I had was beacause the crop was so small as original shot was at 200mm opposed to 18mm the crop went was small, I have took the smaller ones shown below...

@trouty00: The objective of Part B is to duplicate the field of view. I see that you were trying to achieve this with respect to the background. The difficulty is that your subject was much closer than the background and the relative change in distance was much greater for the boat. I'm considering giving you a pass on Part B just for pointing out this difficulty with the assignment.

Cheers... Brian

ok, so are you saying its the FOV which needs to be replciated or thr size of subject. I feel i did get pretty close to the FOV as to me seems similar amount of hedge to the left and water to the right as original image. I do agree the that boat is different size so looking for direction here...


or are we trying to replicate both and maybe because of my original shot and distance from boat may actually be impossible?

My point exactly! It's impossible given the distance between the subject (boat) and background. Pieter (pegelli) and I will have to have a consider modifying the text of the assignment, but you get a pass on Part B for pointing out this difficulty so clearly.

excellent, I have been wondering how in movies they retain the size of subject but bring more background into shot or vice versa, I guess this is same principle and they are zooming in whilst moving backward on track. just part c to work on then but a very very interesting lesson so thank you!!

Part A:

Reference shot at 26mm with 18-55 kit lens


Same position at 200mm with 70-300 SSM G


Crop of 26mm reference shot (shown above) showing same field of view:


Comparison shows that the wide-angle crop gives an identical FoV to the telephoto - even the depth of field on the wide angle is similarly small at that magnification.

Part B
View taken with wide-angle (18mm)


With 'normal' (35mm)


With telephoto (100mm)


'Telephoto compression' renders further-away objects larger in comparison to nearer objects.

Part C

Shot of figure taken from standing height


Shot of figure from same spot, but crouching down


Crouching allows the hiding of lamp-post and other distracting items in background.

Now that I own all three types of lenses, I can finally take a stab at this assignment.   Here goes.


Part A: Telephoto Compression


Assignment #4: Perspective - Part A - Normal
1/30 Sec    f/1.8    35mm    ISO 100    Sony SLT-A65V    Sony 35mm f1.8 SAM


Assignment #4: Perspective - Part A - Telephoto
1/10 Sec    f/4.0    75mm    ISO 100    Sony SLT-A65V    Minolta 70-210mm f/4.0 (Beercan)


Assignment #4: Perspective - Part A - Cropped Wide Angle


Assignment #4: Perspective - Part A - Wide Angle
1/10 Sec    f/2.8    16mm    ISO 100    Sony SLT-A65V    Tokina ATX Pro 11mm-16mm f2.8


Part B: Zoom with your Feet


Assignment #4: Perspective - Part B - Telephoto
1/8 Sec    f/4.0    210mm    ISO 100     Sony SLT-A65V   Minolta 70-210mm f/4.0 (Beercan)


Assignment #4: Perspective - Part B - Standard
1/10 Sec    f/4.5    26mm    ISO 100    Sony SLT-A65V    Sony DT 18-55mm F3.5-5.6 SAM (SAL-1855)


Assignment #4: Perspective - Part B - Wide Angle
1/13 Sec    f/2.8    16mm    ISO 100    Sony SLT-A65V    Tokina ATX Pro 11mm-16mm f2.8


Part C: Hide and Seek


Assignment #4: Perspective - Part C - Before
1/160 Sec    f/6.3    18mm    ISO 100    Sony SLT-A65V    Sony DT 18-55mm F3.5-5.6 SAM (SAL-1855)

Coming down a steep hill toward a fenced off pipe bridge, I saw down the bridge and stopped, pointed my camera and shot.


Assignment #4: Perspective - Part C - After
1/100 Sec    f/5.0    18mm    ISO 100    Sony SLT-A65V    Sony DT 18-55mm F3.5-5.6 SAM (SAL-1855)

Moving to the right, and changing where the camera was aiming, I was able to convey the depth/height more and also show graffiti that was hidden in the previous shot.


EDIT: Forgot to show cropped Wide Angle - added in.

@DWardCA: I'm glad you added the crop since that was the point of Part A. You have an extra image in Part A that was not required (but interesting nonetheless). The DOF and relatively dark exposure in the Part A telephoto shot makes it hard to see the compression. The swingset does appear to be farther away in the cropped shot. So... there's your pass on Part A. Parts B and C are executed perfectly! You picked a particularly good subject in Part B and retained the size of the subject in the frame for all three shots. Well done.

Cheers... Brian
