Hi!

I work in photoshop.
I have cartoon strips in bl/w that I want to give colour. If I use the magic tool and fill: the black lines will be ugly. There are some areas in the picture that are grayscale and I want to add coulor to this area without removing the grayscale.
I want you to tell me how I do a mask of the bl/w picture. If I have a mask of the whole bl/w picture I can use the mask, after I have fill the coulours(that damage the black lines), and repear all the lines and all the grayscale areas just to simply use the fill funkton with black coulour when the mask is turned on.
Can´t I in some way read/loade in a bl/w image to the masks in the layers windows?
Or do you have any sugestions of the easiast way to fill coulour to an image like this?
There are many strips, so I want a way to do it quick and easy.

While I'm not 100% certain what you're trying to do, I think I can offer some advice.

It seems you have one picture that you want to mask?  For this I would recommend using the selection tool and alpha channels.  Make a selection using the selection tool and refine the selection, then save the whole thing using select -> save selection.  The other thing you might want to try is the QuickMask, which are the buttons located at the bottom of the P-shop tool bar.  With QuickMask on (the right button) you can actually "paint" the mask over the image, without having to worry about pixel by pixel type selections...

The image will have to be in some color mode for you to paint color onto it.  You can't keep an image in Grayscale and apply color.  Switching from grayscale to a color mode (RGB for instance) will keep the gray information in the underlying image.  Then you can use layers to apply the color fills, which makes it easy to remove them if you don't like them...

Hope this helps...

I think that drawing a selection outline by hand may be more work than you need to do.

If you continue to use the Magicwand tool and the Fill command (or the Paintbucket tool, which is the same thing, really) you can control your results by adjusting the "tolerance". The tolerance adjust is in the tool options window for each tool (just double click on the tool, and the window will appear.)

If I understand you correctly, it seems that you when you fill a black outline with a color, the inside of the outline shows gray pixels which are part of the anti-aliasing of the outline.  If you set the tolerance value higher, you will paint over the gray pixels, leaving a cleaner color fill.

Suppose, however, that inside the object you want to fill, there is some gray shading that you want to preserve. I suggest the following:

-create a new layer
-make the original layer active
-use the magic wand tool (with tolerance set to where you want it) to select the area you want to fill.
-now make the new layer active (*** the selection outline remains in effect for the blank layer! ***)
-use the fill command to color the selected area.
-now, in the Layers palette, with the new layer selected, change the layer mode from "normal" to "multiply". (or experiment with other layer modes.)

This method will preserve any grey shading that lies within an outline that you would like to fill with a color.

If none of these answers help, then please write a  more detailed description of what you are trying to accomplish, and why this didn't work.  I'll be happy to give you further/better advise if you wish.

Good Luck,
Bradley

Hello

I have alredy tried thouse things you mention. I can do it that way but it would take to long, i have´t got so mutch time and there are many stripes.

I think there must be a way to make a picture into a mask. When you ara in the quick mask mode you can paint, use differents filters and work with the mask as it was a ordinary picture but you work in grayscales. So when I have a bl/w picture I want to opend it/copy and paste it/ add it in some way to the mask, so the picture become a mask with grayscale.

I want this funktion because it would be so easy to just use it and fill with black in a layer above, then I have got a layer with just black ansd transparansy, and after I have filled the strip whith coulour(that are in the layer under) I still have the ordinary black lines and grayscales.

I hope you undestand my bad english, and understand what I mean.
I want all the white coloure informations in my pixels just to dessepear and turn into transparancy.

Thanks fore helping me.

This thing drives me crasy, there MUST be a way to turn a image into a mask.

Greetings,
Yes I understand you--your english is good.

Yes, you can turn your picture into a mask.
Try this:
- Select:All of your original gray-scale image
- Go to the Channels palette and in the pull down menu on the palette, select New Channel.
- Make the new channel active, and paste your image.
- To use this new channel as a mask, use Select:Load Selection. You will be able to choose the new channel you just created, and then click ok to apply to channel as a selection outline.

- You probably know this already, but keep in mind that this selection mask will fully mask parts of the image that are black, but will only partially mask gray areas.  So, if you create a new layer and fill the mask with black, you will preserve the gray areas of your image.

- If you want the mask to not preserve the gray areas, then before you use Select:Load Selection, do this:
- Make the mask channel active, and use Image:Adjust:Levels to make the make the gray parts of the mask channel black.  (If you're not familiar with Levels, just locate the black triangle under the Input graph and slide the black triangle to the right.)

I hope that this information will stop you from going crazy!
 
Good Luck,  Bradley

If you are scanning your drawings, scan them at a relatively high resolution - even if you are going to be reproducing them on the web - 300 dpi should be good.

- Use the magic wand tool, with a selection rating of about 32
- Click the area you want to color
- Create a new layer (to protect your original layer)
- Go to the menu item SELECT-->MODIFY-->EXPAND, and enter a value of between 1 and 5 if you scanned at 300 dpi. (you'll have to experiment) another option is also to FEATHER the selection by 1 or 2 pixels.
- EDIT-->FILL your desired color.
Repeat as needed
