How can I do this?

[jrgdz]

Hello Guys, I just registered to ask this. I am a newbie and I would really appreciate your help.

I have a bunch of images like these ones.

Some drawings in a white sheet of paper. However, the white sheet of paper looks grey, due to the lighting at the moment of taking the picture.

What I want to do is, make the white part look completely white, without affecting the colors of the drawings at all. (If there is a way to do it to a bunch of different images at the same time, that would save me tons of time)

Thank you very much for your help.

JRGZ,

Welcome to the forum.

The effect you are looking to do is definitely possible. It all depends on how much time you want to spend.

Take a look at the image below. This took about 2 minutes.

I opened up the magician image in Ps, duplicated the layer, then added a LEVELS adjustment to the copied layer, adding a clipping mask.

So I'll break it down into some basic steps.

After you duplicate your layer, click on the half-filled-in circle icon at the bottom of your layers panel (see small red circle). select LEVELS from the pop-up menu, then slide the two outside (black and white) sliders inward, until you are happy with the results.

Right click on this LEVELS adjustment layer, and choose "Create Clipping Mask" from the menu.

Create a new layer above your original background layer (use the square icon with the folded corner in your layers panel) and fill that layer with white (make your foreground color white and hit ALT+Backspace).

Next click on your copied image layer, and use the eraser to erase whatever parts of the gray paper background are still visible.

You should get something similar to what I have.

Hello and welcome to PSG.

As always, there's more than one way to do things in Photoshop.

In order to preserve the color of the drawing, I would use COLOR RANGE to make a first selection of the back ground.


Then I would use the Quick Selection Tool to clean up that selection............


The I would use that selection to create a layer mask.

With an all white layer beneath it, it will look like this.........
