Join Jan Kabili for an in-depth discussion in this video Using the Background Eraser tool, part of Photoshop CS4 Essential Training.
The Background Eraser tool does two jobs for you in one.…It both selects and deletes pixels at the same time.…It's often the best choice for selecting a neutral background like this one,…when you have a lot of fine detail in the foreground.…What I want to do here is select this neutral sky, so I can replace it with a…more interesting image.…So I'll select the Background Eraser tool from the toolbox right here, behind…the Eraser tool and I am going to go up to the Options bar.…I want to make sure that this first sample 1's icon is selected.…This works fine when I have a background that is pretty much one color, like this one.…
If I had a multicolored background, then I would select the next option, which…would sample continuously as I moved the tool around the image.…I am also going to set the Limits to Discontiguous, and that will allow me to…select pixels that aren't necessarily touching one another.…I'll leave the Tolerance at its default.…When I click on a pixel of a particular color and tone, Tolerance determines the…

Q: How can artwork be transferred from Photoshop CS4 to Illustrator CS4 without the background?
A: Save the image in Photoshop’s native PSD format. The background in Photoshop must be transparent, meaning there should be no background layer. (To remove a background layer, move your artwork to a separate layer by selecting and copying the content, minus the background, to a new layer, and then delete the background layer. A checkboard pattern behind your image indicates transparent pixels.)
Q: How do I retouch an image I have of an old photograph I scanned?
A: There are a few courses that address image restoration. Check out the Photoshop CS4 Portrait Retouching Essential Training course, and for problems dealing specifically with old photographs, watch the Restoration movies in chapter 15 of the Enhancing Digital Photography with Photoshop CS2. Additionally, learn how to research and date photos with our Growing and Sharing Your Family Tree course.
Q: A client has asked for artwork to be delivered as JPEGs or BMP files in 16-bit format. In Photoshop CS4, there does not appear to be an option to save an image as a 16-bit JPEG. Is there a way to save JPEG files as 16-bit in Photoshop?
A: Unfortunately, JPEGs cannot be saved in 16 bit. JPEGs, by nature, are 8-bit. So if you open a high-bit image into Photoshop CS4, you will see no option in any of the save dialog boxes to save the file as a JPEG. You would first have to convert the image to 8 bit (by choosing Image > Mode > 8 bits/channel) and then save it as an 8-bit JPEG. If you open a high-bit image into Photoshop CS5, you will see the option to save it as a JPEG in the Save, Save As, and Save for Web dialog boxes. But the JPEG will not be saved as 16-bit. Instead, Photoshop will downsample it to 8-bit for you before saving it as JPEG.
