Photoshop :: Eliminating White Backgrounds On Scanned-in Sketches
Jun 24, 2002
How to eliminate the white backgrounds on scanned-in sketches/line art.
1. Open the scanned art work in Photoshop. Make sure that the color mode is set to RGB Color.
If the background is a pure white, skip to step 4. If the background is grayish, go on to the next step.
2. Open the Levels window (Ctrl+L). You should now see a jagged pattern in the center with three arrows right below it. Drag the Black arrow to the right until the background is almost white or until the lines are about to go jagged-mode on you. Click OK to apply the changes.
3. Now adjust the Brightness/Contrast (Image->Adjust->Brightness/Contrast) and move the Contrast slider until the background is white.
4. Select All (Ctrl+A) and copy (Ctrl+C). Open the Channels window if it isn't out already (Window->Show Channels). Click on the Create new Channel button and Paste (Ctrl+V) into that channel.
5. While having the Channel selected, Invert (Ctrl+I) the image.
6. Click on the Load Channel as Selection button and a marquee should now surround the white lines.
7. Go back to your Layers window and click on the Create new Layer button. While having the foreground color set as black, fill the selection with the foreground twice (Alt+Backspace)X2. This should now leave you with the outline of the pencil strokes minus the white background.
8. Delete the original image layer and place a layer filled with white below it.

I scanned a family photo and the result is about 25% of a letter size sheet.
I wish to attach this to a 'My Family' post, but the result I desire is just he photo without the white space around the photo.

I have a black logo with complex lines, text, etc. The only copies I have of the logo are with a white background (probably from having been saved on a document page?). I want the logo to have a neutral/clear background so that I can paste it on pages with gradient backgrounds, etc. and not have the white show.

I've just set up a new macbook air from a time machine back up and for some reason my cursors in illustrator 5.5 are white making it very difficult to use. All was and is still fine on my macbook pro with the same version.

I cannot get a perfect white background. I use white balance and save in my camera (Canon 40D) and process using CS3. My background is grey, I have tried using exposure and or brightness and my subject looses detail.

I have just built a new PC and re-installed my Adobe CS4 Master Collection. When I first opened Photoshop, the default white background was a Yellow colour. Eventually I worked out that it was to do with colour profiles and selected a profile associated with my monitor (Samsung Natural Color Pro 1.0 ICM). This turned the Yellow back to white and all was good. Now I am trying to edit some product photography sent by a supplier and though the images look fine in the windows thumbnail, when I load it into PS, the white background of the image is yellow. On closer inspection, if I preview the original files in Windows, I see the Yellow backgrounds. The Yellow background also stays if I save the file and then will show on the thumbnail as yellow.

1. Why does the eraser sometimes erase with white vs. the checkered background?
2. Does the checkerboard mean that the background will be fully transparent?
3. How do you switch between checkerboard and white backgrounds for the eraser?

I am having some trouble clearing out the backgrounds of certain images. I'm taking images and want to quickly delete out any pixels not on the product I'm shooting (make all pixels white). Once I have my selection I go to "Edit" and then "Clear". Instead of making the selection white, it makes the entire selection black.

I have 6 rectangular photos and I'd like to put each of them on 6 square white backgrounds and then save the resulting images (it's for posting on Instagram - it's crazy that they don't allow you to post rectangles, but there you go). What would the most time-efficient way of doing this be?

i want layer 1 to overlap layer 2 as if i had erased the white background on layer 1 but i want do it quickly eg by applying a layer style instead of using the magic eraser which can be unpredictable without using the lasso tool to restrict it.
what if the multiply blending mode was applied more intelligently: here's what i mean in pseudo ..IF at least one of the overlapping pixels in either layer is white..THEN apply multiply mode as normal ie multiply the pixel values and divide by 255.
IF neither of the pixels is white THEN only display the pixel in the uppermost layer (in this case layer 1).
i want to speed up the whole process by selecting multiple layers and applying a saved layer style or some other equally rapid method of making the white background transparent.I am not interested in solutions involving the magic eraser, layer masks or anything that can't be applied in one go . I have looked at the 'blend if' sliders in the layer style window but this needs per layer adjustment so is not a time saver and does not always give a smooth overlap anyway.

Im trying to make an icon (.ico) with transparent background. Im adding an alpha channel and deletes the fields that are supposed to be transparent. Everything looks just fine in Gimp, but when putting the icon on the desktop there appears a white border around my icon. The transparency works within the icon. Im using Windows Vista 32bit. In Exporer it looks like it has a border too.

I have some 3x5 glossy photos taken from about ten years ago. They are no longer in the best condition, and have dust specs and superficial scratches on them. Recently, I decided to scan them and was less-than-happy with the result.
For example, one of the photo's is of me and my friend against a blue-ish wall behind us. The entire scanned image, though, is covered in little white specs. I have black hair, but it looks almost as if i have dandruff lol. even the blue background has a bunch of little white speckles
I was wondering if there was a tool or filter or other way to remove some of the small white specs from the picture.

I think Divide Scanned Photos feature is amazing! [URL] ....
For those scans I put black construction paper in the rear, it works like a charm.
However, my mom scanned multiple photos prior to us finding Elements and did not use a dark background.
Is there any way to salvage this or is it too late?
When we attempt to Divide Scanned Photos on a set of B&W photos with a white background, no luck.
PSE11 just spits out a copy of the same photo.

I've got a little graphic that I'm working on at the moment. I am trying to trace it using the Image Trace feature in illustrator.
Everything's hunky dory apart from the fact that the original graphic has a lot of white features on it that I want to preserve. These white bits are not bordered so, in the main page of illustrator, they merge with the white background. When I go to use Image Trace, I can either select "Ignore white" which leaves out all of this white detailing, or I can deselect it which means that the trace then includes the white background and the whole image is set into an annoying box.
how I can remedy this? I know in Photoshop, there's that checked background that shows when your work surface is empty. Is there a way of getting this same thing in Illustrator?

I am currently running Gimp 2.8 and am a new user. How to make an image's background white. I have a watercolor painting that I have scanned into my computer, however you can see some shadows from the grain and edges of the paper. I have tried some different ways to change the background completely to white, but I feel like maybe I'm missing out on a quicker method. So far, the one I've been working on is taking me longer than it took to even draw and paint the picture in the first place. That method was to use the fuzzy (lasso) tool, make a rough outline of my painting, use the quick mask button in the bottom left hand corner and follow up by using the pencil tool to make a more precise line around the image.
Another tutorial I found showed I should use the Select by color tool, select an area that should be white in my image and press Ctrl+x. However, when I pushed ctrl+x, I saw no change in my background and my image remained outlined in the shifting lines that the select by color tool causes.
Is there a way to achieve a plain white background with out going through the long process of tracing around the detailed image?
It should be noted that I'm not hugely familiar with Gimp as I've only used it a couple of times with tutorials. So, the more basic you can describe something, the better. I am also running Windows 7.

I'm creating two websites for two different clients, and both gave me scanned copies of their logos. I converted them to GIF, JPG, BMP and PNG (from MS paint program), followed all the directions found online in various combinations to remove the white background from these logos. Here's a sample of what I did:
import logo; edit bitmap; change background; used magic wand on white areas; close paint & export doc. I've tried various combinations of clicking on options like transparency, masking, changing the tolerance and nothing works.
On one the white background simply won't go away after saving to my desktop, and on the other there is a grey/white checkerboard pattern on the background.
When it's all said & done, I need to upload these to Wix.com as a PNG.
I'm at my wits end been trying to do this for two days after work, wondering if Corel is even capable of doing this, or if my clients' logos are just unusable or if I'm just losing it.

I scanned a black and white print in color and am trying to replace all the black with dark green. Been trying for hours in elements 9. This is all so hard. Just to ask this question I have typed it into 3 different screens, set screenname, many other hurdles.

I have this image with an intense orange background.
I want to change the color of the background to a light green, or even white (depending on my boss' mood). But the background color leaves me with an undesirable orange color-cast on the old man.
this is only a very rough clipping, the final version will be well refined.
way to eliminate this color-cast, most noticable on his hair. How would you go about it?

I'm attempting clean up some JPG images of product for sale. I do not know the technical terms for what I am attempting to do. I wish to eliminate all of the background space. I wish for the file to display only the product as if floating in empty white space.
I am using Adobe Photoshop Limited Edition; I also may use Adobe Illustrator.

I have a schematic that I scanned in and cleaned up PS. When it scanned there was a lot of background noise in a strip up the center of the file.
I've removed most of it and darkened the image itself back up and am pretty happy with the way it prints directly from PS. However, I need to convert it to a pdf (it is part of a manual that needs to be available online). Everytime I do it it comes out horrible with all sorts of fuzz and noise around the entire scanned image. The text comes out okay.
how I can eliminate the noise in the pdf?

I just upgraded from PSE 7 and I absolutely cannot stand that they made the parts circled in my image un-moveable (as far as I can tell). Any fix for minimizing these? In my opinion the "Open/Quick/Guided/Expert" panel is an utter waste of space.

When I went to add text to a video sequence in the Title feature, the words "Double-click Here to Add Text" appeared.
Which I did. The text I wanted appeared in the sequence and showed up OK after saving and replay--but so did that "Double-Click Here to Add Text!"
I couldn't figure out how to delete THAT unwanted message--any hints on how to do that?

I recently stopped using my HP755 plotter and am now plotting "dwg to pdf". The problem is when I go to plot I get a warning message stating that "this plotter configuration cannot be used" and it goes on to list a few reasons why and selects the "none" plotter. Then when at the plot setup page I can continue to plot as I normally would. Why am I getting this warning and how do I stop it?

I have a subdivision plat that I'm working on with a curved lot line. When I label this particular lot line, Civil 3D labels it like it's two different segments. In other words, instead of labeling the line as a 100 foot long arc with a radius of 100 feet, it labels it as a 60 foot arc and a 40 foot arc. I can't figure out how to combine the two segments.
All of the lots lines were created from polyline objects, and there was no break in the original line work (nor is there any indication of a break in this location when I select it).

The image above is for a website which has a colored background. The image will be exported as a PNG file so that the background is transparent. I am unable to eliminate the space above 40th. It seems the bounding box around the character can not go past the artboard area. Is there a way to crop in Illustrator or do something to the character so that it is flush at the top on the artboard area?
