I'm trying to understand how the normal blend mode works in photoshop.
http://www.pegtop.net/delphi/articles/blendmodes/normal.htm
As the webpage says,it just shows the color of the layer above.But when I copy the same layer and show them together,the color seems darker than just show one layer.And when I add more,the color remains at a particular value.
The normal blend mode shows the color of the topmost fully opaque layer, for transparent layers it will add from top down until fully opaque is reached.
This means that if you have a fully opaque red element over any, for example, blue element, the color red will be displayed. If you have a red element that's 50% transparent over a blue element, the color pink will be displayed.
If you have one black element that is 50% transparent it will appear as a medium gray, if you duplicate the layer, the two elements on top of each other will add up to display a complete black.

I have a colored image from photoshop where the background is transparent well as some other spots. After using image scan and expand, the transparent background was gone so I reselected the design I made and copied it to another layer. The white background is gone, however, I see that there are still white spots in the design that wasn't transparent.
I selected them and deleted them, but, it gives me black instead of transparent.
I'm out of ideas as to how to make these white spots transparent. The same thing with my signature- although I can erase it completely, if I just erase the white parts, I get black.

Hi guys! I have the following task: I must paint the black and white house, leaning to a result as the colored one.
I figured out, there must be a way to somehow "remove" the white color, so there is only the black outlines left. From there I will make an underlayer and will insert color/materials etc.
The hard part and the essential in my question is: The black outlines are ranging from true black to very light grey. Is there a way I can somehow delete all white (0,0,0) pixels and for the others: the more "black" they have, the more opacity they get. So a grey pixel with a value around (126,126,126) will be left, but with a 50% opacity.
have you tried, copying the same image on top of the original image, change the copied image blending mode to overlay, use the select tool on the white area, and then click the select tab on top menu, from that tab click select similar,so you have all the white area selected, then select the original layer, and then erase, you can also erase delete the copied image. Good Luck!
Yes you can,
Open "Select" menu and choose "Color Range", it will open a dialog box, inside that box you can choose from the drop down at the top if you want to select Reds, Yellows, Greens, etc. or you can select Sampled Colors with the eyedropper tool, so you can select the white color from anywhere at the image then you can handle the color range sensitivity from the slide bar called Fuzziness, the lower number is the lower range of white color and vise versa :)
As Ahmed Alaa said, use the "Color Range" tool, but for coloring in black and white images, see if my Youtube tutorial can help.

P.S. Sorry this post is bad, i'm new-ish.
I am a newbie to photoshop. I have some images that I need to label by hand to feed to a machine learning algorithm for classification.
The labeling accepted by the code bundle I will be running on is supposed to depict the features I am interested in, and the other unlabeled pixels are to be black.
For instance, I have a picture of land, and I will have to paint on it with red to mark the rocks, and blue to mark the soil. The other regions in the picture will be black. SO my labeling image should have red (rock) and blue (soil) and black (unclassified).
I am told I need to do this with transparent layer on top of my actual picture, and I can paint on the transparent layer as I want, and save that transparent layer as my label image.
My questions are:
How do I draw on the transparent layer (I am reducing the opacity to
0 because I want a transparent layer, right?)
How do I paint the unlabeled pixels black? (because that is what the program recognizes
as unclassified)
How do I save the transparent layer as a 8-bit image?
Thanks!
1) Anything you draw on a layer with zero opacity will not show! You need an empty layer, not a zero opacity layer. To make this, ensure your Layers palette is visible by pressing F7. Then, at the bottom right corner of the Layers palette, beside the trashcan, select New layer.
2) To paint pixels black, press d for default colours since black is the default colour. Then press B for Brush. Now you can paint on the empty layer. Press [ to make the brush smaller and ] to make it bigger. Click the black foreground colour square on top of the square white background colour in the Tool palette (left side of my picture) to change colours.
3) To save the classification layer only, click on the eye icon in the Layers palette of the other layers that you don't want in order to turn them off. That way only the layer you want will be saved. Then click File->Save for Web and select a file format that supports transparency - i.e. PNG or GIF, but NOT JPEG or TIF.
I have marked in green, all the buttons I mention that you will need to click on.
When a PowerPoint presentation is run in a slide show window that is not the same aspect ratio as the presentation design, black bars appear at the top and bottom or left and right (depending on the window size). For example, when presenting a 16:9 deck on to a 4:3 display, black bars appear above and below the content.
I am trying to change the default color from black.
The VBA object model for SlideShowWindows does not appear to have a property to do this.
I have checked the Win API for SetSysColors (user32.dll) and this doesn't appear to affect the slide show window background color either.
Is there a way to override this color?
There's no way to change the black bars that appear in this situation.
I have this element in my psd layout
I need to remove green rectangle and leave a gray box with a gap at the top (in place of the green rectangle) and save as .png. How can I remove green rectangle?
select Magic Wand Tool (press W on keyboard), then select the
green area and then press Backspace to remove it.
Then Create new Layer with white background and set it as background
layer,
Then create your own gray layer.
