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 ...

One method is to use the original image/layer as its own layer mask. You'd create a duplicate of the layer, desaturate and invert it, pasting the greyscale result into the original layers layermask. Update: Here are some step by step instructions: Start with your flattened image: Add a Saturation/Hue adjustment layer and turn down the Saturation until ...

First you'll want to desaturate the image (CMD+SHIFT+U), this removes any color and makes it easier to achieve pure white. With your file open, choose Image->Adjustments->Levels. You'll get this: Now bring the two outer triangles in like this (you'll need to play around with this until you get something you like): You should end up with this!

I came up with a nice method for cleaning up pictures like this, and it works even when the background or lighting is uneven (that is, far worse cases than the example in this question) and it retains the colour. My instructions are based on the Gimp, but it would be very similar in other programs like Photoshop. Firstly, make a duplicate of the layer: ...

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 ...

You can use blending to add transparency: Ensure that the Background layer has been unlocked, and set to 0% opacity (transparent). Right click the layer you want to add transparency to, pick the "Blending Options..." Locate the scale under the "This layer:" that is under the "Blend if" box Press and hold the alt key while dragging on the white knob, the ...

Ramp the contrast up with curves. Instructions: Select your image and press Ctrl-M. This will bring up the curves dialog. Move the top point left and the bottom point right until your image becomes black and white. (that rhymes!)

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 ...

Here are the steps I took: Duplicate the base layer and select the copy. Apply an edge detect filter (Filters -> Edge-Detect -> Edge...) using these settings: My goal here is to get clear contrast between my object and my background. I found Sobel worked the best and simply fiddled until I got this result. Threshold the colors (Colors -> Threshold...) ...

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 ...

This is called defringing, and Photoshop has a Defringe tool right under Layer > Matting. However, you might not even need that tool in most cases if you're using the Quick Select with Refine Edge in CS5, or the Extract filter in earlier versions.

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 ...

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 ...

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 ...

Welcome to Graphic Design. If the smoke doesn't have any colors in it, you could use the smoke image to create a layer mask on a white layer. This would change the blending to simple alpha channel instead of doing blending that is dependent on lower-layer pixels.

Personally, I would rebuild the image from scratch because I find it frustrating not to have original source files. But, until you or someone else gets around to doing that, here's the non-destructive quick fix: d (changes default fg/bg colors to black & white) CTRL+SHIFT+n (create new layer) press OK/enter SHIFT+b (selects the path tool) Roughly ...

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 ...

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 ...

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. ...

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 ...

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

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.

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 ...

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 ...


3

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 ...

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..

All you need to do is choose Image > Adjustments > Levels and alter the levels within the image. Simply drag the left triangle (black) to the right to darken the dark areas and then drag the right (white) arrow to the left to lighten the lighter areas on the image. Viewing the histogram will help. It shows the ramp on the right which is all the ...
