You don't see the transparency effect if there's nothing below the layer because there's nothing there for Photoshop to calculate (all these blend modes involve calculations based on the values of the corresponding pixels on each layer), so it just shows you the image. In this particular case (as Farray pointed out while I was writing this!), you can pull ...

To expand on utopicam's answer, sometimes your image might contain areas, such as shadows, that you'd want to be semitransparent. For example, let's say you have a photo shot in a lightbox, such as this nice and freely licensed picture of a Swedish wooden toy horse courtesy of Creative Tools: In general, the first step would be to adjust the levels of ...

GIMP's Color to Alpha tool is very handy if you know how to use it, and this task seems particularly well suited for it: Open the image in GIMP, and change it to RGB color mode if necessary. Select Layer → Transparency → Color to Alpha... Select black (#000000) as the color to make transparent. Click "OK". Save the resulting image in PNG format: ...

The main trick, in my experience, to adding smooth transparency to an image in GIMP is using the Layer → Transparency → Color to Alpha... tool. Of course, you have to know how to use it to good effect — on its own, all it does is make your images look all funny and translucent. If I take the image you posted above, and just run Color to ...

On the Layer window change the mode of the fire layer from "Normal" to either Screen or Lighten and see if thats what you want. That's the easiest way to remove black. Beyond that you can also go into the Blending Options and adjust the slider at the bottom where it says, "This Layer" and move the black tab on the left side in a bit but the results aren't ...

This will require a little experimentation. As with most things in Photoshop, there are multiple ways to get there. Method 1: Eyedropper a solid part of the red cloud to make it the foreground color. Choose Select > Color Range. Set your Selection Preview to "Grayscale" and the preview thumbnail to "Image" so you can see what you're doing. Uncheck ...

And just to be complete, here is the GIMP answer. Just do: Colors > Color to Alpha ... select Black Click OK if "Color to Alpha ..." is greyed out you need to set the Image mode to something else than indexed, e.g.: Image > Mode > RGB

Greenfish Icon Editor Pro has this functionality out of the box. It is a function called "Remove Matte", where you just specify the color component you want to be replaced with transparency. In your case black. This is the result: Greenfish Icon Editor Pro is totally free of charge. It is by far the best free icon editor I have ever tried. From the ...

The feature you are looking for recreating background is content aware fill, which is already part of your photoshop (if you have a recent one). Google those exact words for tutorials and videos how to use it. Also, Adobe Help describes the use of this tool.

Yes, it's possible. Let me outline how it's done, using this image from Wikimedia Commons (by ed_g2s, licensed as CC-By-SA 3.0) as an example: Open the black and white background versions as layers of the same image (using Open as Layers... or just open both and copy-and-paste one into the other). Move the white layer above the black layer if it's not ...

use mask tool(press q) then brush all the area which u want to remove(press q again).and press delete. when u get that logo alone paste it to new white background then brush or delete those black dots,zoom it to the maximum for pixel perfection i do the same when i have to work on small things.. hope u understood..

Its important to select the area you wish to cut/cutout very accurately. No automated tools will clean cut for you without having a good selection to start with. that said this is my method: I will regularly zoom in few hundred percent and using magnetic lasso to trace around the object or person. with add-to or subtract-from selection you can get it ...

Sounds like you need to crop certain parts of the jpgs (the main figure, for example) and delete the "background". You can do so using the lasso tool. The gimp website has lots of tutorials and explanations. Check this http://docs.gimp.org/en/gimp-painting.html#gimp-concepts-selection and this out: http://docs.gimp.org/en/gimp-tool-free-select.html The ...

Unfortunately there is no easy quick-fix for this My typical method of choice is; Go to the channels panel, toggle through the Red Green and Blue options to see which has the most contrast, duplicate this layer and then ctrl/cmd+l the levels slider to increase this. Then using the brush on this layer colour in black what you want and white what you don't. ...

The grid you are seeing is just the Pixel Grid. It is helpful when working with very small resolutions (such as icons/cursors). You can enable or disable it with View → Show → Pixel Grid To make a cursor with transparency, I would follow the tutorial here

In the GIMP, getting rid of the background would be as easy as opening the file, selecting Colors → Color to Alpha... and choosing black (#000000) as the color to make transparent. Here's the result, saved as a transparent PNG: In Photoshop that's a little bit trickier, but apparently there's a free plugin that can do it. (That said, in this case ...

If you have fireworks, you could use it to convert this image to alpha (filter > other > convert to alpha - it works similar to multiplay, but actually converts the white pixels to permanent transparency). Then bring the alpha channel back into photoshop which you could then mask over the original image. You will need to play with the levels to keep the ...

The obvious suggestion would be to reshoot with a better background. Back when I had to do something like that, I found a plain green bed sheet to work just fine. However, if you have to work with the shots you've got, one thing you could try would be taking the difference of the two shots (preferably using the "grain extract" layer mode) and using the ...

Just found this for you: http://www.howtogeek.com/59634/remove-backgrounds-automatically-with-a-free-photoshop-action/ I guess it would work if your client doesn't need perfect masks for them (which would be okay for a webpage, since everything is small anyway) But professionally speaking, I would mask them out one by one, just so nothing goes wrong. ...

The problem here is that the image has a "fade-to white" at the edges, and you have not removed this. The fade or anti-aliasing is achieved using greys which become high contrast against darker colors. I don't use GIMP, but in simple terms, the easiest way work with this is to make a new layer on the bottom of the layer stack and flood fill it with a color ...

You could use the GIMP's select by color tool or the Magic Wand tool. Anyhow you do it, just select all the black pixels. Then, instead of deleting the selected pixels, apply a layer mask: Layer -> Mask -> Add layer mask Select the "Selection" radio button and be sure to select the "Invert mask" checkbox. Now, all the black pixels are transparent. ...

I don't use gimp, but this image is a simple case where it should be straightforward to derive a decent transparency. If you select the entire image, and then use that (or rather the greyscale version) as an alpha channel, you are pretty much done. Depending on your software export features, you can just pick the alpha as the PNG transparency or you can ...

You can try RGGJAN fork of GIMP available at partha.com (bottom links in the left sidebar). It has an improved tool for selecting objects. You just select general area, mark the object with a brush, and you get your selection. Here is a video: http://www.youtube.com/watch?feature=player_embedded&v=kkQ1r5g49d4

I'm not familiar with GIMP or Paint.NET, but there is a nice plugin for Photoshop called "kill white". This removes white areas from an image. After applying this filter you can then refill the white areas if there were any removed. Hope this helps. http://mikes3d.com/extra/scripting-plugins/killwhite/

Theres two ways that i would use to do this in photoshop: 1. Make selection from red channel Go to Channels window and click red channel while holdin Ctrl button to make selection out of it. Make sure youre back in rgb channel and go back to layers window. Copy the selection Ctrl+j and there you go. You could also invert slection and delete the ...

Those answers are all pretty long ways to achieve your goal. An easier way is to simply command-click on the layer thumbnail to select the object/shape, then go to Select > Modify > Contract then contract the selection by a pixel or two, depending on your needs. Next step is to hit command+I to invert the selection then hit the delete key.

You can use the magnetic lasso tool (or regular lasso tool) to crudely select the logo. Then, invert the selection (Selection>Invert), and hit the Del key. Alternatively, you can select the background with the magic wand tool and delete it(I will talk about an effect to erase all the little dots later) If you used the lasso tool, then use the magic wand ...
