OK guys, which is which?

normhead · 08-20-2014, 11:22 AM

Because I take images on "Photgraphy Excursions" with various clients, and we often send each other links to each others photos, I have access to their pictures, often FF and mine, always APS_c...

So here's 3 pairs of pictures. Which is FF, which is APS-c....
1.

2.

3.

4.

5.

6.

3 FF images, 3 APS_c images

Guess the numbers of the 3 FF images...

probably want to remove EXIF on first image

other than that I honestly can't tell, especially with landscape shots, which is often the case ...

nomadkng · 08-20-2014, 11:36 AM

because YOU took the APS-C images, I'm guessing 2/4/6 are APS-C because they have better exposure, composition and white balance...lol

actually, I'd guess APS-C 2,3 & 6 because I believe I detect a slight bit of edge distortion in each of those that would indicate a wider lens was used to get the same FoV.

I had a sigma 12-24 that was a FF lens and it was great on APS-C because most of the edge distortion was cropped off by the smaller image circle. on film, I really didn't like it so much because it looked a lot like the sigma 10-20 on aps-c, with trees and edges distorted at weird angles along the edge.

I'm really seeing that in number 3. in number six the rocks along the left edge are definitely more distorted than in 5 and in 2 the land along the center horizon seems much more minimized, indicating a shorter focal length compared to 1.

Woo hoo, we have a customer...

**Rondec** · 08-20-2014, 11:50 AM

I think 1, 3 and 5 are APS-C.

I don't care which format, I'm just saying "ooh, pretty!"

Ya we got some nice pictures on that trip. This year he came back for more, and it rained 4 of the 6 days. You win some you lose some.

I have my opinions, but know well enough that none of those shots contains any particular clues.

And you think they could have? Wat wid dat? Oh, I get it, you need me to select pictures that include clues.. silly me?
By the way, you got 2 out of 3 wrong, not that anyone is keeping score, it's just for fun.

6BQ5 · 08-20-2014, 12:29 PM

Hmm... as always, it's hard to guess with well done images what the sensor format was. Just for grins, here's my guess:

1) APS
2) FF
3) FF
4) APS
5) APS
6) FF

Nice shots !

I thought 2,3 and 6 were the FF ones! Viewing on my cheapo laptop is probably not the best way to decide, mind! Ive been offered a cheap D700 body -tempted to give it a go and do my own comparisons with the K5 I use on a daily basis!!

6BQ5 posted as I ws typing...at least we agree (even if wrong)... maybe I should post some of my old 35mm and 645 film shots and do the spot the difference thing as well

For this year's photos, you can sneak a Pentax Q shot in there!

I'm guessing 1, 3, 5 are the FF images, based entirely on your preference for cooler rendering... and APS-C sensors.

BrianR · 08-20-2014, 12:53 PM

I know you said they're in pairs, but I'm going to guess 3 and 4 are APS-C and the rest are FF. The arrows are indicating that stuff got cropped off. Obvious.

Come on now, you really don't think as a former teacher, I'd make all of one odd and all of the other even? I did take a course on "test design" you know.

My guess, I've written at least 500 multiple choice tests.

The arrows on that set are because they are both photobucket screen caps... actually they all are (I figured out how to avoid the arrows on the others.), that way whatever Photobucket does to them is constant among the images. I do put a little time into these things, retired as I am.

You'd like me to think that, wouldn't you?
