 Posted: Sun Mar 02, 2003 9:01 am Post subject: A good way to get the background cut out... |
 |
|
At 2bigfeet.com we take all our own product photography with a little home-made studio (just a digital camera, some lights and a posterboard-backdrop).
We've always had a tough time cutting out the background, especially on grey or white shoes because they are so similar. Does anyone have any advice that would make it easier without washing out the photos meddling with the contrast?
Thanks...

Unless it's super complicated, I just add a layer mask and paint around the object. Never takes longer than a few minutes.

There's a couple neat ways to do this.
One of my favorites is the magnetic lasso. You just use it to go around the foreground part and slect it. Then invert the selction and delete.
Another one is in the image menu. Go to extract. The menu is pretty straight forward.
And then as acecool said the magic eraser |

Yes! Extract! I forgot about Extract! You can do some amazing things with it. always make a copy first, so you can rubber-stamp back in any spots you didn't want removed.

We currently use the magic wand or the magnetic lasso - but they don't always work when the product is grey or white.

Magic Wand and Magnetic Lasso tools are so hit and miss I find. For the actual photo shoot perhaps using a grey backboard that will not be reflective of light and will also allow for easier colour correcting in Photoshop.
I would probably opt for a masking technique for the extraction, it is difficult to say which one would help most without examining the image or it's channels, but even quick mask would give cleaner results I would think than magnetic lasso.
Here is a link to Stephen Marsh's wealth of information on masking and indeed all things PS http://members.ozemail.com.au/~binaryfx/PSTV_links.html#H. It's a bit dry in places but I know of no better proffesional resource.

Agreed. I very rarely use either. Even when I do, I almost always have to clean up the whole edge with a brush anyway.
Just used masking tools from the start.
Extract is fantastic but I don't like that it just deletes the pixels. I just made an action to overcome this

This might help:
1- duplicate the photo layer
2- sharpen the new layer using Unsharp mask(so the edges of the shoes are more solid and distinct.
3-play around with the levels,contrast...etc filters until the background is a solid white or close to being so.
4-use the magic wand to select the white space (background).
5-with this selection still intact, go back to the original photo layer and hit "delete".
----------------
another idea...do it like the movies...and shoot against blue background instead of a white one

I'm telling you guys, when contrast is low, you're gonna have to get down and dirty with a mask layer and your brush tool, and leave all those automated processes (wand, extract, etc) behind.
Not everything can be solved with 3 clicks
