Correcting bulging due to perspective
Hey all. In the process of making a brochure for a new product here at work, I needed to take pictures of the product in question. However, due to perspective, this product ended up having a rounded bulging look to it. Any suggestions as to how to "straighten out" this product?
Here's a link to the photo. The "bulginess" isn't as apparent in the low-res version, but you can see it some.
Thorax 48, Hi!
Yes, it is distorted.
Did not take to much trouble to correct.
• Made some guides as a reference.
• Duplicated original and created CS3 Smart Object.
• First Transformed and rotated 1.0.
• Then used filter Distort>Lens Correction with these settings:
Remove Distortion 2.10 and Vertical Perspective +2.
Here are the results:
You will then need to Crop or Trim image.
Hope that helps.
This was a quickie to get you started.
Because it is a Smart Object, you can fiddle with the rotation and Lens Correction settings.
I see in PS CS4, Smart Object finally got LINKED Layer Masks.
It took Adobe two versions later to fix that oversight or bug.

Ooooh, never saw the Lens Correction filter before. Learn something new every day. Thanks, KRB!
Out of curiosity, what's the significance of turning it into a smart object first?
Glad I could help Thorax.
I learn something new every time I turn on this computer.
Look at Help for more info about Smart Object.
I used Smart Object on your image for easy non-destructive editing for the first Transform rotation and then again to adjust the Lens Correction settings.
Get to know Smart Objects and CS3 Smart Filters.
Google some tutorials.
Smart Objects just got smarter in CS4 as I mentioned.
Adobe added a link to Layer mask. No more workarounds.
Also you now can do a Transform Perspective on Smart Objects.
