From the first contact PS5.0 to now, PS has a lot of functionality, and PS will always retain the functionality of the old version, which I have been following the new version of PS trend. In this there are many enhancements to the function for a purpose, reuse (reuse), do not damage the original piece, can be edited later. Implementation of a lot of features, slightly interested in the following, slowly explained later. Masks, channels, history, lay

strokes A 0.5pt stroke is displayed as a single pixel in 2x, and a softer, single pixel in 1x, with a vector stroke that is not an integer (a layer style stroke cannot be set to a non-integer) Similarly also used for 3x display--0.33pt strokes are automatically adjusted to 1 pixels. 　　Half Pixel light shift Turn on Photoshop's snap pixel feature to help create sharp graphics. If you want to move exactly half a pixel, turn off the pixel alignment and zoom the view to 200% to nudge the half p

update the original smart object, you copy the Smart object will also change. This feature is useful when you need to copy multiple identical layers and expect them to change synchronously. To convert a Smart object: Right-click the layer and choose Convert to Smart object. Figure 01 Use file > Placement commands to place the picture Most of the time, we use Photoshop to open a picture and then copy and paste it into another document. While there's nothing wrong with this, in

can create a dream of light, human skin has a slight sense of light, the whole picture is full of a hazy beauty. Applicable scenario: This combination is ideal for situations where there is no need to change the exposure of a large area, but also to create a hazy feeling. How to use: Note The Gaussian blur value, the greater the value of Gaussian blur, the scope of diffusion (fuzzy range) will be larger. Pay attention to adjusting the opacity as needed. Note the use of combined

1. Work within a single layer Although there are many tutorials on the Dantu layer to create the effect of XXX, you may wish to learn as a practice, grasp the idea can be. But at work, this habit is really bad. Single layer mapping, lack of flexibility, can not be targeted to make changes. The safest way to do this is to have an effect, a new layer, so it's convenient to modify it later. In any case, use as many layers as possible in your work, editing is more efficient and orga

features: masks, vector masks, or clipping masks. The easiest way to do this is to add a mask to the layer to mask part of the layer. The mask can temporarily mask the contents of the layer's selection, which will be visible when the mask is disabled. Use masks instead of deleting parts of layers 　3. Too

A mask can create a cut-out effect for an object, changing the appearance of the object.Masks are grouped by at least 2 objects, one is changed, the other is a masked object, and the Mask object can be divided into vector masks and bitmap masks. After the mask is created, it remains fully editable and can be modified, deleted, and disabled.The mask mainly has 2 main uses: 　　 change the shape of an object:As
