How do I use a mask to cut out fine animal hair in Photoshop CS5?

1. Open ** and use the "Polygon Lasso Tool" to cut out the character;

2. Ctrl+J to copy and paste the layer;

3. Turn off the background layer, save it in png format**, and you're done.

I don't fully understand the effect you want, if you want a transparent layer, just check the object you want and copy the layer, and then delete the original background layer, it's transparent, if the background can't be deleted, double-click the background layer to change it to a layer.

Press Ctrl+J to keep the circle line in the key image, then close the old layer, save as a PSD image, and end.

If the original layer is not needed, you can pull it to the trash can and throw it away, **too large to re-crop.

You can create a new canvas with a transparent background, put the picture into it, and then save it in tiff format, and then there will be a choice when you save it, I can't remember it clearly, it seems that there is a storage pyramid, transparency, etc., just select it, and you're good to go.

GIF PNG format can be a transparent background, just save it in both formats.

Open** - Duplicate a layer, create a new layer between the background layer and the layer copy, fill in a single color to check the effect of the cutout, select the layer copy, click Filter - Extract, check the forced foreground color, the eyedropper tool absorbs the hair color, use the edge highlighter to paint the hair area that needs to be cut out, and after confirmation, cut out the hair.

cs5 version: Select the character you want to deduct first, right-click, adjust the edge, and select the appropriate parameters, and you're good to go, it's better to choose the auto radius, which is faster and better than extracting.

Click on the channel panel, there are three channels of red, green and blue by default, see which channel has a clear contrast in black and white, copy a channel, adjust the effect of black and white, if there is a part of the adjustment, you can use the brush tool to paint until the character and background color are completely black and white, click on the channel panel to create a selection.

Install an extraction filter, and if the background contrasts sharply with the color of the keyed subject, you can use the extraction filter directly. If the contrast is not clear, cut out the picture in the channel, be careful and patient.

Quick Selection tool. The one below the magic wand.

Use the border tool, frame it, lock the layer, and delete it with the selection tool.

Quickly select the tool and adjust the edges.

1. First open the ** that you want to cut out the red seal, and then click [Color Range] in [Select] 2. In the box that pops up, select [Red].

3. Generally, the color tolerance and so on are used to select the red chapter, and in this kind of color distinction, you can directly sample the color [red] to quickly select the approximate model of the red chapter.

4. Ctrl+C to copy, after creating a new layer, Ctrl+V is pasted into the new layer.

5. There are still flaws, so they need to be retouched. With the eyedropper tool, absorb the color of the red badge, and then use the brush tool, pencil tool, and other modification tools to retouch the imperfections.

4. Create a new layer, 100% fill the white background, and you can clearly see a perfect red seal.

Unless you use tools such as curves or filters, it is recommended that you copy the layer, select the layer you are not ready to use, and delete the redundant layer after selecting it before proceeding to the next step.

You can change the way it is displayed! As you said, the display of red should be a superimposed display method, and it is best to choose a white background display to pick out the hair with adjusting the edges, so that the contrast is large and easy to observe!

Hair is more difficult to handle, so you can try it with a pull filter.

Use the color channel, find the color channel, there will be 4, total, r, g, b, close three, find the most obvious black and white contrast, ctrl+alt+g, select, invert, copy, paste, and that's it.

Generally, the magic wand tool is used to regenerate the path, and if the pen drawing is more solid, the pen drawing is not natural enough.

To cut out, the background color itself is not much different from the color to be cut out, and the edge will definitely not be selected with a magnetic lasso, and a pen is the best.

If this kind of edge is clearer, the magnetic lasso tool is good.

However, I prefer the pen tool, so I don't need to make modifications, one-time.

The steps of the method are as follows:

1. Tool requirements.
