Light and Shadow: Glass bottles to the background

Step 1 Hook up the outline of the glass bottle with the pen tool, Ctrl+enter (convert the path to a selection), Ctrl+shift+i (reverse , Ctrl+alt+d (feathering the selection 1-2 pixels, which will make the edge look smoother), delete (delete). The glass The bottle is dragged onto the background, as shown in Figure 1. Step 2 Hide the background layer, switch to the channel panel, select a contrast to the most distinctive channel, copy, and now we're going to make the dark part of the glass bottle. Select the copied channel, Ctrl+l (color level), in the pop-up dialog box to strengthen the contrast to the appropriate degree, I use here is: input levels: 84,0.69,255 output levels: 0,255 because in the channel, the white part is the selected area, so to ctrl+i (reverse phase), Reverse the white and black portions of the channel, as shown in Figure 2. Step3 Let's take a look at the production of the high-light part of the constituency. Go back to the layers panel, create a layer underneath the glass layer, fill in the black, as shown in Figure 3, switch to the channel panel, and select a contrasting channel to copy. Select the copied channel, Ctrl+l (level), in the pop-up dialog box to strengthen the contrast to the appropriate degree, parameters: input levels: 60,0.18,248 output levels: 0,255 Use the Pen tool to create the selection as shown in the figure, and then use the Brush tool Carefully spray the central and bottom parts of the bottle into the black (this method is too careful, I used the method is: the selection feather to moderate, such as: 20, filled with black, if you want to more subtle effect, it is best to the bottle body selection and the bottom of the selection of the bottle to separate, feather to the appropriate refill, as shown in Figure 5. At this point we have completed the production of the high light and dark parts of the constituency. Step 4 Back to the layers panel, hide the original glass bottle layer and the black background layer, displays a green background layer and sets the foreground color to dark green with the background color (because the glass is reflective of the ambient color, we will make the dark side of the glass into the same color as the background, allowing the glass to blend with the whole picture), Switch to the channel panel, pull out the dark part of the glass, go back to the layers panel, create a new layer, and fill the selection with a dark green, as shown in Figure 6. Step 5 Switch to the channel panel, pull out the glass top, go back to the layers panel, create a new layer, fill the selected area with white, well, a crystal clear glass bottle has appeared in front of us, as shown in Figure 7.
