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 ...

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 ...

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 ...

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 ...

Seems pretty straightforward with Photoshop CS6. I used the dropper tool to select the general background and did cleanup with the quick selection tool. Note: If the selection of the background ends up breaking due to the "grid pattern", you can work around it, like I did, by duplicating the later and applying a blur filter to smooth it out, then ...

There are lots of methods to achieve what you want in Photoshop. You can use a non-destructive method such as a layered Gradient Map. Simply create a new adjustment layer from Layer > New Adjustment Layer > Gradient Map... Choose the Black to White Gradient and adjust the gradient stops accordingly. Make sure that the adjustment layer is on top of the ...

I don't believe that the option exists as print-layout software is focused on laying ink on paper. Since "white" is the absence of ink, it acts as a transparent background. Keep on mind that unless you are laying a base of ink as a spot color on top of your specialty paper, you will not have any "white" areas in your print. In fact all non-black colors will ...

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 ...

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.

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 ...

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

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 ...

If you have access to Photoshop, try the Magic Wand tool to select the background around the writing, and fiddle with the Tolerance to get it as close to the writing as possible, then delete or fill with white. Another method is to use Image > Adjustments > Selective Colour - With Selective Colour you can tweak the thresholds of each colour, so in ...

Let me outline another approach I find useful especially in the context of a signature for letters or PDF documents. We can quite easily create a vector graphic from a scanned original signature. This can be done with a variety of applications. Here is how I made it using Inkscape. Import the bitmap into an empty document (select "embed"). Select the ...

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. ...

In Photoshop CS5 they introduced better options for the Refine Edge Tool over CS4: Awhile back I ran into this issue and saw a very good video in regards to removing backgrounds from hair by Terry White called "How to Remove a Background from an Image in Photoshop CS5"

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 ...

Yes, this can be possible, although Inkscape may not be the optimal tool for it. What you probably want for a job like this is a raster graphics editor like GIMP or Photoshop, not a vector graphics editor like Inkscape. Without seeing the actual picture, though, it's hard to say just what could be done with it and how. Still, just to show what is ...

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

Adobe changed the Delete/Backspace key functionality in Photoshop CS6 when you press the Delete/Backspace key on a locked Background layer. Since pressing the Delete/Backspace key on a locked background layer merely filled the selection with the background color, Adobe changed the functionality to provide more options when hitting the key. By bringing up ...

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 ...

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

For sending a document to be printed, don't use PNG as the export format. There are three reasons for this: A printing press uses CMYK, and PNG is an RGB-only format. If your document contains text, that text will be rasterized and will print at the resolution of your PNG (perhaps 300 ppi) instead of the 2800 dpi at which live text or vector information is ...

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 ...

I don't have a lot of experience with this personally, so take it with a grain of salt, but in portraiture, it is not uncommon to photograph someone against a "pure white" backdrop. One of the problems is that the white blows out the subject if you stop it for the white, and even when the subject is exposed properly, there is a lot of "light bleed" around ...
