moz's dumb question #1

I've always enjoyed taking photos, but I've only recently started taking it a bit more seriously. I'm still a complete n00b and expect to happily stay that way until my dying days, but I'm having fun and that's all that really counts.

Half of the fun though is learning, and I must admit, real learning can only be done by asking stupid questions.

Here is a remarkably stupid question for you (no doubt the first of many!) - How do you acheive the "wrap around" effect that you can see here in Athiril's excellent photo...

Is it acheived by a specific lens type or by certain camera settings?

Wrap around? Looks pretty straight and even to me, more converging to a point in the horizon than wrapping around (Unless that's what you meant).

Composition and perspective.
A wider lense does help with shots like that, but aren't necessary for it.
It's all in how you compose the picture, and part of composition is perspective.
I'm not going to risk mis-explaining it, so I'll just throw one of my own into the open :)

I dont know what you mean by wrap around, but it may be the effect of the moving clouds, due to a long exposure, its also a HDR (had no choice), as I also didnt shoot this on reala.

I also have the extreme perspecive of 12mm there, Sigma 12-24mm EX DG (full frame, but on a 30D, lens has no distortions at wide end.


I used a further shadows and highlights after tone mapping, some noise reduction on a separate layer, blended with the layer below with opacity to put back in detail, then a lot of local contrast boostng (unsharp mask: 250px radius, 55% amount, ran it a second tmie with less too i think..), little bit of sharpening, black and white conversion on a new layer with blue toning, masking in the golden area.

Burning in the bridge, and clouds on shadows mode with 5% on large soft brush... thats the tech/post-proc info at least..

Yes, you do not need a wider lens, but wider is awesome for perspective, and obviously large field of view images... and may i say the sigma 12-24mm EX is freakin amazing.

I guess what I am referring to is the "wide angle" or panoramic effect. You often see the images have a definate wrap-around sense to them.

Athiril. your piccie may not be a perfect example of what I was referring to, but it does have some elements of it.

You just answered your own question : ). You want a wide angle lens. In the 35mm film world, that's roughly defined as anything less than 50mm, and in the digital SLR world less than about 30mm. That 50mm/30mm mark is what we call the 'standard' view - pretty close to the range the human eye sees. They're different because of the difference in size between a film frame and a sensor frame.

on an APS-C 28mm and 24mm gives you a standard field of view, though of course they'll have a different perspective than their "focal length equivalents" on a 35mm camera.

Aye, I thought as much.

Thanks for the help folks. :)
