As in Photoshop to make a black background?

Ideal exposed frame and chosen background can be seen not so often. Especially a lot of questions arise when it comes to the background in black - get a deep and rich black tone without glare and "traces" of the outbreak is difficult. However, there is a solution - an artificial replacement of the background pictures.

Replacement of the existing background on black - "cutting" the object

Launch Photoshop graphics editor. Open the photo that needs to be corrected.
Go to the "Layers" ( "Layers") tab.
Clicking double-clicking on the base layer, you take away the lock - a new window appears with a proposal to rename the background sheet. Call it, for example, "Background" or "Sheet 0" - as you will be clearer. Click "OK".
You will see that the padlock icon in your base layer disappeared.
You create a new list by pressing the bottom of the tab corresponding icon layers - with bent sheet icon area.
Fill it with black. To do this, go to the toolbar. Install black. Now you are interested in "Fill" (inverted bucket dripping or a rectangle with a gradient transition).

Click on it with the right mouse button. Among the items dropped out of the list choose the proper fill (or "Paint Bucket Tool"). The new layer will acquire a black tone.
The next step - the selection of your object. Go to the tab layers and drag your mouse over the background create a black layer. It is necessary to cut the object to be placed on a black background. This can be done by such separation means, such as:

Rapid release ( "Quick Selection Tool").
Magic Wand ( "Magic Wand Tool").
Adaptations of the "Lasso" ( "Lasso", "Poligonal Lasso", "Magnetic Lasso").

Receiving a selection of a particular separation depends on the color uniformity or inhomogeneity of the processed images.

When you arrange the result of the allocation of the main object photo, clamp the combination of "Ctrl + Shift + I". This set of keys allows you to invert your object by highlighting the entire area beyond.
Delete it by clicking "Delete" or "Backspace".
Black background "sticks out", and you will see a carved object on a black background.

The border of the selection will almost certainly be coarse and not very attractive. Make a soft transition between the picture and the background will allow the blur ("Bloor"). It is only necessary to choose the necessary rigidity, the diameter of the brush and the degree of transparency.

The final stage is the combination of the layers. To do this, use the combination of hot keys "Ctrl + SHIFT + E".

Replacing an existing background for black - use mask

Method 1

Open the photo editing.
Remove the blocking of the background.
Create a new sheet by clicking the corresponding icon in the layers panel (icon from a leaf with a bent corner).

Next, refer to the tool palette - in the colors field, install the black front of the foreground.
Take a brush ("Brush") and start painted background pictures black.

Create a mask by clicking "Mask Icon" (at the bottom of the layers tab, find the icon with the image of a light field with a black circle in the center). You have added a mask in the upper layer.

In the Layers Palette layers section, find the item responsible for transparency - "OPACITY". Set this parameter within 50-60% - you must see through the picture.

Check the mask icon - it must still be for the top layer. Color parts of the image that you are inappropriately poured with a black tone.

Method 2.

This method manifests itself well when working with simple plots that have clear contours and good color contrast.

Opening the image, remove the ban on its editing - double click on the lock in the layer panel.
Next, create a new sheet and pour it in black (front color - black, choose the fill tool).
Remove the visibility of a new sheet by clicking the icon with the image of the eye.
Using the isolation tool (Lasso, magic or fast selection), outline the contours of the desired object.
