For stock, is distortion acceptable? I mean the background, beer and other items on the table.

How do I prevent distortion like that? Different lens? Different focal length? Different distance to subject?

Or is it unavoidable in any set up?

Thanks,

I wouldn't submit any distortion on my images unless you are looking for a special effect. What lens are you using? I looks like you pushed the lens to either extremes - trying using a setting in the middle ranges for example say you have a 24-200 F/2.8 lens try it at say 35 to 160 at F/4.0 this should remove your distortion.

24-70 at 24mm

You could try using the perspective crop tool in photoshop, That might work for you Ron?
You would need a wider angle to work with.

Also try the Lens Corrections tools in ACR or see if there's an equivalent in what processor you use.
I'm usually pleasantly surprised. But some distortions defeat them.

Try 35 to 50mm range. Yes, you can fix it in the processing software but why not nail it in the camera if you can...

Thanks, I have the correction tool selected for my lens but that is the end result.

Cool, will play around with that next time I take such a shot

Shooting tabletop with a wide angle will produce distortion. I shoot all of my tabletop stuff with Canon EF 100mm, f/2.8 Macro lens. There is zero distortion. Here's an example of something shot at a similar angle to your shot:

Thanks Danny, Canon EF 100mm, f/2.8 Macro is on my wishlist, probably the next lens I will purchase. Or super wide angle 14mm, but thats for other uses.

Try the ACR lens correction under the custom tab. Play with the sliders at the bottom. It may surprise you.

Ron, that's not very healthy food. It could lead to distortions also in other places.

lol! A barrel effect for sure that would have to be Photoshopped out...

There is an easy way to fix just the glass but since you all are a buncha SA's I am sure you can figure it out on your own.

Dont worry, I lost 80 pounds, I am enjoying these little rewards. Plus it was taken July 2014. It has long been burned up.

Trying to fix that kind of distortion on the computer lowers the image quality and not worth the effort me thinks. Your best bet is to use a prime lens and avoid less than 50mm range.hope that helps

Semmick Photo · « **Reply #16 on:** February 22, 2015, 08:54 »

Well I just like to mess around in photoshop.

Next time I will use my 50mm or take the middle of the 24-70.

I think this one is fine now, not sure if it was worth the effort but I had fun doing it. Win win.

Semmick Photo · « **Reply #17 on:** February 22, 2015, 08:56 »

Tony, that was my first try too, but I came to the same conclusion as you, so I posted here for more advice. Thanks.

Trying to reduce keystoning in architectural shots using perspective adjustment reduces quality because it interpolates. This is the reverse of that, you are squishing the pixels together, so I don't see why that would reduce IQ. There are 24-70 lenses out there that are very nearly as good as any prime and with the lens correction software available today are pretty much unbeatable.
The trick to shooting food with a wide-angle lens is to get in really close so the perspective is not so obvious. I shot for a while full frame with a Zeiss Jena 35mm Flektogon (manual) lens and got some pleasing results.

But your DOF is based on stacking, right?
