Use the channel to pull out the model that wears a wedding dress

Original

Final effect

1, the original image is a fashion show at the wedding dress pictures. Because of the light reason, the image appears to be somewhat partial color. Because the bias is not too serious, you can use the Auto Color command in the image → adjust menu to correct it nicely.

2, observe the image of red, green, blue 3 color channels. Although you can start from the red, green, blue 3 color channels of any copy to begin to modify, we still feel the use of the image of the "gray" channel more in line with the translucent features of the wedding, you can use the "calculation" command, according to the image set to get the "gray" channel "ALPHA1

3, use the "level" command to set the image of the black and white field, which will ensure that the background is completely removed, white is retained. The above belongs to the preparatory work.

4, because it is the scene of the fashion conference, you can see the background is not simple. The following figure indicates the 3 areas in the ALPHA1 channel where the eraser can be wiped completely.

5, models of the body, skirts and other than the wedding, is completely opaque, it is best to use the pen tool carefully outline outline, and then converted to the selection fill white. When converting, using a feather value of 0.5 pixels makes the contour boundary softer, which is why you don't use the fill path directly.

6, the use of sponge tools, the mode is set to "Add color", by increasing the contrast, modify the model headdress and leg edge. As you can see, highlight the highlight area and darken the residual background near the hand. In this case, the use of sponge tools is better than the use of deepening and Dodge tools.

7, can be reversed with the "reverse-phase" command image. Because of the different sensitivity of the human eye to the light and shade, some areas that are easily overlooked can be found. For example, the darkened area, where we think it is dark enough, often finds no erasure or uniformity after the inverse phase. Note which areas need to be modified. Photoshop is a pixel-based software that does not distinguish which pixels "useful" need to be retained and which pixels "useless" need to be removed. The decision of choice rests with the operator. There is no tool to Pauta, to be good at synthesizing various tools. For example, the Clone Stamp tool retains details and textures, but is slightly stiff; the Healing brush tool and the repair tool reconcile textures and shades, but do not work well with edges; the fade-and-burn tool has a better effect on changing shades and shades, but you should be aware of setting a smaller exposure value.

8, use the "Select All", "Copy" and "Paste" command to paste the "Alpha1" image as "Layer 1", and change the layer mode to "brightness." As you can see, the shading in this area of the image meets the requirements, but the color is inconsistent.

9, edit the "background" layer. Using the color substitution tool, set the mode to Hue, select the foreground color of black, and smear in the color anomaly area until the exception color disappears.

10. Use new layer mask on the Layer menu, select Hide All, and create a black mask for layer 1. Because Layer 1 is hidden, the user can see the area in the background layer where the color has just been erased.

11. Select the Brush tool smudge, which will mask the defects of the background layer using the pixel "Layer 1".

12, merging layers. Use the "ALPHA1" channel to end changes to the background layer.

13, drag into a "castle" image as the background. However, this layer does not have to be placed below the original image. Load the ALPHA1 channel as a selection, use Create layer mask, select Hide selection, and the corresponding area on layer 1 is hollowed out, exposing the background layer of the model. Loading a selection directly and wiping it with an eraser is not an appropriate practice in most cases. Creating a layer mask preserves the possibility of more changes. After the replacement is complete, there is nothing to be done, such as the color and hue of the wedding dress and the castle is not naturally fused, need to make some changes to two images. Castle color dimming, saturation increase may be more suitable for the overall image of the atmosphere. But there's no fixed pattern. The following approach is just to provide a way of thinking

14, click the previous thumbnail of the "Layer 1" thumbnail. Use the average filter in the Blur filter group. This filter can "average" the entire layer as a color. Use the Eyedropper tool to set the foreground color to that type.

15. Open the "Fade" command on the Edit menu and change the mode to "strong light", which will give the castle a dim but high saturation effect.

16, switch to the "background" layer, load the "ALPHA1" channel, reversed-phase selection, using the "Fill" command, the color of the "foreground" (just the color chosen by the straw), the pattern of "color", making translucent wedding dress with a faint blue.
