How do I make a picture all in gray-scale, but leave one object in color?

I've been wanting to do this for a while, but I have no idea how to. Do I need a certain kind of software? What kind? Would Picasa work? And once I get it, what do I have to do to work it?





Thanks so much!How do I make a picture all in gray-scale, but leave one object in color?
Photoshop. Duplicate your original image (never work on the original), then duplicate the working image and do a Mode: grayscale. Revert back to RGB mode, select ALL copy and then paste it on top of your first working image.





You will have two layers. The top will be Gray, the bottom color. Use your outline tool (I like using the polygram for complete control) after zooming into the area you want to edit. Once you have selected the area you want to change back to color, you can either feather the edges or do a direct erasure of the gray. Flatten.





Done.





There are also other ways to do this... you can select the area you want to remain color with the tool and then Select Inverse and adjust color to remove all... same results.





There is yet another... numerous ways to make changes and everyone has a favorite or one they prefer over or know of. I don't know about Picassa but some say it's limited or not able to perform correctly.





You could get Paint Shop Pro (version 4.12 is free on the internet) and you'd be very happy with it for now too.

You can do that using Adobe Photoshop. You make a duplicate layer of the background, and turn the copy layer to BW. Then you turn on a mask layer and paint through the copy layer to show the colored part of the background layer underneath. Flatten the image and save as a jpg.





I'm not familiar with Picasa, you may be able to do something similar if it works roughly the same way as photoshop. I know Paint Shop Pro works this was too.
Picasa wont do it properly.





You need to look for a programme that works with layers, such as photoshop, PSP, or Gimp.


You can download Photoshop CS4 on a 30 day free trial.

from my stand point i know nothing about picassa. I have photoshop which can be expensive, but for alll intensive purposes photoshop elements 7 is about $130 or so. I have used this technique. best way to view it is probably. you can view my thread with out becoming a member but if you are into photography this is a great place to be
