I think this maybe a stupid question, but say i had a image with a person on it and I wanted to select the person and leave out the background and use the drag tool to put it on my new project?

well the only way you can do it is to use the lasso tool and select around the person and then copy and paste itonto the new image.

It's not a stupid question as the heart of being able to do a lot of stuff is being able to isolate an image and get it out of there (I usually copy it after I isolate it myself).

You can also use the magic wand tool. Sometimes you can select the background and then inverse it and thereby get the image. My sister likes the liquify command but I have never been successful with it. The magnetic lasso sometimes also works for me -- make lots of stop points. If the background is all pretty much one color you can also select by color.

I just isolated a bunch of airplanes for buttons (see www.GeorgeSpangenberg.com if you are interested). It is so much easier than people though.

although the magic wand and lassoo tools work they are not ideal, in any way. The only way either of these tools work well is if the background is very simple.

The best method to use to isolate a section of the image which has a complicated background is to use the pen tool and use the bezier curves to get a perfect cut-out of the image. Then right-click and use make selection and voila, copy-n-paste it into the required image.

Hope this helps,

Matt

This is my usual process for remove stuff from photos-

* go to image/adjustments/levels (or just press ctrl+L)

* adjust to taste, but typically bring the black and white sliders in (usually want to cut out the flat spots in the graph on either edge + a tiny bit more), and i prefer to slide the gray slider left to brighten the image (that's my own style)

* go to select/color range (if you've never used this tool before you may need to play with it for a bit first).

* first turn the fuzziness down to zero, then hold shift (look for a little + on your cursor) and click'n scribble inside the subject you want to cut out of the image. Be careful you don't go outside the lines at all.

* slowly turn up the fuzziness to soften the edge of your selection. If anything outside the desired part of the image shows up as grey AT ALL (that inludes dark DARK grey, anything besides black) then you've turned it up too high. But mostly you'll want to focus on everything right around the border of your subject. Things farther out can more easilly be removed with the lasso tool.

* once you have your selection, use the lasso tool with shift held and trace just inside the inner part of your current selection to select stray or partially selected pixels that don't show on screen (less than 50% selected).

* repeat around the ouside with the alt key held down to remove the unwanted 50%ers (make sure you use a horseshoe shape around your subject, don't simply draw a circle or you'll just deselect everything you have).


I've found that with small adjustment here and there that this method works the best for me 9 times out of 10 when dealing with photographs. Of course, in photoshop there's 100 other ways to acomplish anything, this is just mine.

Yeah i totaly agree, thats the best way to "cut off" a complicated section with the best results. (not the easiest way)

Another way is to use a mask. Apply a filter mask to the layer that has the information that you want to show..

I use a mask for this purpose, especially when the contrast between your subject and it's background is not great.

- Open your photo
- Set your foreground/background colors to default (black and white)
- Turn on quick mask mode (filled circle box under your fg/bg color boxes)
- Select a hard round brush and with BLACK selected 'paint' over the section that you will be extracting from the background. It will look like you're applying a red mask over the area.
-When you're done covering your desired area, turn off quick mask mode (white circle, left side of toolbox) and you'll see the 'marching ants' of your selection.
- You can refine the selection by going back into quickmask mode. To ADD to the selection, "paint" with black. To SUBTRACT from the selection, 'paint' with white.
-When you're satisfied with your selection, feather the selection by a few pixels, then copy and paste your selection to your new file.

I tend to copy the whole layer WITH the mask into a new file so that I can always further refine the masked selection. Painting on the mask, along the edges with a SOFT brush works very well to eliminate the edges of a selection.

If you have a solid color background as from a white or chroma background from a photographers studio, you can select the background using the color range select. This will look most natural, IF your background had a strong contrast from the subject.

If you want to take hair or other very detailed images out from the background you and also use EXTRACT under filter.


The two i use most often use are the 'colour range' feature and ' polygonal tool'.

MAYBE the magnetic lasso, but NEVER just the lasso by itself if your looking for a good outcome. Mess around with the features of the selections too, like the tolerance levels... that works well too for certain backgrounds.
