Good Morning, all…

I am using Photoshop 7 and am trying to add individual red (255,0,0) pixels which
I’ve generated in a raw transparent file (File1) using Grain=>Sprinkles. I started out by filling File1 with red, then using the Grain=>Sprinkles, Intensity
97, Contrast 100 so that individual red pixels remain on File1.

I then want to select a region of File2 (another raw file) and have the pixels from
File1 to populate File2. I can’t seem to get the pixels to populate the region of
File2 without a white background. I want the background of File1 to be transparent and only overlay the red pixels to File2.

When I create the new File1 and indicate Transparent, I am expecting the transparency representation of the open file, however, it is shown with a white
background. Can you not represent transparency in a raw file?

Any help appreciated…Thanks Bob

Hi Bob.
Try adding the red speckles to a new layer above the main image, then change the blending mode of that new layer to "multiply". I’ve just done a quick test on my system here and that seems to do what I think I understand you’re asking.
Hope this helps 🙂

Thank You…but, didn’t work as expected. So, let me restate more simply what I’m trying to do.

File1 is a face of Howdy Doody, File2 is a file of freckles. I want to select Howdy’s cheeks and apply the freckles from File2.

Hope that is a clearer request….Thanks…Bob

Aaaah,
So could you do as before, but then erase the parts of the upper layer that don’t correspond with Howdy Doody’s cheeks?
Sorry if I’m missing the point, but that just seems obvious tome.

In File2, enter quickmask (q) then paint over just the freckles (carefully). Press q again to get out of quickmask. You’ll find they are now selected. Copy the selection (CTRL + C). Go back to File 1. CTRL + V to paste. Use CTRL + T to do some basic adjustment on the freckles you just pasted in, do whatever clean-up you need.

Quick and dirty method.

Ouch. That’s a tedious, painful, inaccurate way to o it. You can di it automatically, with no painting.

Step 1: Use the eyedropper to sample the red.

Step 2: Click the Select menu and choose the "Color Range" command. This will select ONLY the red pixels, automatically.

Step 3: Use the Move tool to move the selected pixels from the first file directly into the second file.

In the image that contains the freckles, use the magic wand tool to select the background. Now, under "Select", click on "Inverse". This will select the red freckles. Now under "Edit" select "Copy". Now go to the picture of the face and under "Edit" select "Paste". This will copy only the freckles to the face.

I’m just curious why you want to move them to the other layer ? Or maybe I have it wrong and you aren’t using layers..
Layers are there to allow fixing mistakes.

ie: Howdy’s face layer 1.
I have no idea how you found a howdy doody face without freckles. Howdy’s freckles : layer 2.

Then just move the freckles around till they’re where you want, and save to web&devices. Don’t even have to merge down.

Okay, I’ve bit my tongue long enough, but now I’ve just gotta know. Who on earth is Howdy Doody?
Is he a rapper or something?

Someone you’ll never have a need to know about, just like Clarabell, Captain Kangaroo, Cowboy Bob, peanut gallery, Princess Summerfall Winterspring , The Flubadub .
But if you’re still interested…
http://www.museum.tv/archives/etv/H/htmlH/howdydoodys/howdyd oodys.htm

or Google Howdy Doody. I have no idea why an image of Alfred E. Neuman would pop up right along side of 2 howdy Doody images. Vague Similarity, but Alfred was born at least 10 years after Howdy.

I’m guessing you’d be more familiar with Jim Henson’s muppets, or Sesame street.

That’s the crude way to do it. Using the eyedropper to select the red color, then using the Select->Color Range command, offers greater control. I highly recommend the Color Range command. If you have never used it, try it–you’ll like it.

Now, under "Select", click on "Inverse". This will select the red freckles. Now under "Edit" select "Copy". Now go to the picture of the face and under "Edit" select "Paste". This will copy only the freckles to the face.

No! Do not use Copy/Paste in Photoshop; it wastes memory. There is an easier way to do it.

A lot of people new to Photoshop don’t realize this, but if you click the Move tool, you can just drag a selection from one window straight into another window. It does exactly the same thing Copy/Paste does, but it’s faster and it does not tie up system memory with holding what’s on the Clipboard.

Aaah, he’s a kids TV show character?
I’m assuming he was pretty much exclusive to the US?
I grew up in the UK and I’m pretty certain he was never broadcast on this side of the pond.
Now Alfred E Newman I do know. He’s the gap toothed grinning child from the front of Mad magazine isn’t he?

One thing I love about photoshop is the number of ways you can go about a job.
Ask 100 people how to do something, and you’ll get about 80 different, equally valid explanations.

Hey there tacit! Yes, I know about clicking the move tool and dragging one image over to another image. Whenever I try to help someone, I try to use the easiest method possible so that I don’t confuse them, in the event they’re a newbie.;o)
I always use the "Copy"(CTRL + C) and "Paste"(CTRL+V) as it allows me a fast way to make numerous pastes by just repeating the CTRL+V. I can close out the source picture once I’ve done the CTRL+C, and it’s one less picture to distract me.
I used the Magic Wand tool and inverted the selection because I thought it would include the various shades of red to pink as the red freckles faded into the white background, whereas using the Eyedropper and Color Range command would not. Playing with the two, it seems that they both don’t select the various shades of red to pink, so there is still some loss in image transfer with either method. Since they both transfer the same amount of the image, it’s easier using your method. My bad.

Without seeing the images you can’t know either way. Unless there is good contrast between freckles and non-freckles, using colour to select may be random. Generally you’re right, I was just giving a dirty quick way!

Yep. That’s what makes all of the Creative Suite programs so fantastic to use. There are so many ways to do everything, meaning you can adapt it to your workflow, or find exciting new techniques to get just the artwork you want… sometimes it’s even fun just to try something in a way you wouldn’t normally, because the result may be unexpectedly cool.

When it comes to masking, layers and blending images together, PhotoShop truly shines. I think the OP just needs to try a few techniques and see what works best for her/him.

Agreed.
That’s my favourite way to while away an evening. Just playing around on photoshop, experimenting with techniques.

Actually, that’s not true. In the Color Range command, you can slide the slider to specify "fuzziness" (ow different two colors must be in order to count as different), and you can use the + and – droppers to add and remove specific colors from the color range selection. The fuzziness slider can create a mask hat includes levels of transparency as well; the magic wand can’t.
