Hello there!

Please advise on how I can do a neater job at the following…

I have a painting (done w/ charcoal) on a white background…I want to select the white background and replace it w/ another color/painting…Selecting the white part using the selection tool w/ tolerance set to 15, I am able to get what I want…However, when I fill in the white part, the jagged edges of the original painting (charcoal one) become disturbingly apparent!

How can i smoothen them? or perhaps make a smoother selection to begin with?

Please refer to following URL for a visual description on my problem…I have there 2 pics – one b4 and one after the color replacement…(notice the edges arnd the charcoal drawing):

Would greatly appreciate some suggestions…thanx in advance! CHEERS!

I don’t have the time to give details right now, but you can use either the blur tool or feather the selection.

Are there 2 separate layers?

Hoi Guys!

Ed A. Ortiz – I have given the blur tool a shot without any significant improvement!

Margaret McDowell – There is just one layer on which the charcoal painting is…Since I select the white b/g on this layer and, using the clone stamp tool, replace the white w/ a painting of my choice – It’s all on one layer.

Any ideas ppl?

Use your magic wand tool set to contiguous and 32 tolerance. Select all the white you can. Save that selection as an alpha channel. Go to the channel pallet and click on the newly saved alpha channel. Give it a gaussian blur – 1-3 radius, you choose. Ctrl-Click on the alpha channel to load it as a selection, Shift-Ctrl-I to invert the selection, add your background.

You’ll have to play with the amount of blur.

Peace,
Tony

Put the new painting on it’s own layer, underneath the charcoal drawing. Change the blending mode of the charcoal drawing layer to "Multiply."

Might also want to paint/fill some white on a layer between the two phosphor suggested – else there is going to be a lot of color coming through the charcoal – could use the selection wand selection followed by a select -> Modify -> Contract, and then gausian blur to pick the area to fill with white……

Make another layer for the painting – put the drawing above that layer, change the drawing mode to multiply…check your pshop user guide for more info on using layers…

Have you tried the extract tool?, i remembered it the other day after doing a tedious selection using the lasso and it’s marvelous and super quick.

Or try this…

Make a new layer above the charcoal drawing and fill it with the color that you want to replace the white. Set the blend mode of your new layer to Darken.

Or this…

copy the original charcoal drawing to layer 1, then as before select the white background area, then to make sure all the white area will be deleated…go to select/modify then in the expand option, select 1/2 pixels.
Then delete the white area, you should end up with your original intended charcoal drawing with no background colour. now when you add your new background it should look alot neater.

THERE’S NO NEED TO DELETE THE WHITE BACKGROUND IF YOU WANT AN UNDERLYING PAINTING TO SHOW THROUGH!

One of the many options Phos, I regularly use Erik’s suggestion. Each to his own.

Hey, Phosphor

No need for the BOLD TEXT, tried out your way and preferred it to the way that I explained to do it! It’s all about learning and sharing…

Thanks, ID. Awe appreciated!
