 Posted: Sat Sep 24, 2011 5:55 am Post subject: Improving Background |
 |
|
Hi, I have a portrait image where the background is fine on one side of the subject, but I would like to improve the opposite side. I have tried using the patch tool and selected an area of bad background and transported it across to the opposite side in source mode and tried it in destination mode. My problem is that the two selected areas, which I would like swapped do not in fact swap. They stay as they are. Does the patch tool have to be set up in any specific way or should things happen automatically? I have seen tutorials on this subject and it seems to be an easy procedure! 
Help!!

Not really sure what you are trying to do with out the image. But, it sounds like you want one side to be switched to the other side? Have you tried selecting the background image and then transform it vertically? That is a really easy way to get an object on the other side.... |

The patch tool will try to blend the patched area gently into what is already there. You don't flip from source to destination during a single operation. You choose first whether you want to patch over a "source" or patch from a "destination".
You might be more interested in the clone tool, which makes an exact copy. Choose the clone tool, ALT-click on a source area, then start painting where you want that area cloned. You can set various things like the softeness/hardness of the brush, opacity etc. If you want to get really fancy, there's a whole clone source panel (window>clone source) which lets you choose up to 5 source points, rotate angles etc...
But usually just using the clone tool with a hard brush works quite well.
If you just want to duplicate the right hand side by flipping it over on top of the left hand side, you could try:
- select the half you want
- put it in a new layer (ctrl-j)
- edit>transform>flip horizontal (for left/right duplication)
- slide the new layer over to the other side to cover the bad bit
You will get a problem because you will see a hard edge where the new layer overlaps the original background. To avoid this, add a layer mask (see the layer panel) and add a black to white gradient on the mask so the black part of the gradient masks/hides the join. This will make the two halves blend gradually together.
The above duplication of the background assumes that the background is on a layer by itself.
Now, after all that I suspect it's not really what you want to do exactly... but good luck anyway and just ask again if you need more help.

Hi renata,
Thanks for the advice. I have played around with the methods you discussed but I think the only solution is to re-shoot. To make it look good I think you would have to be a magician and have the patience of a saint!!
Thanks for your help,
