Some thoughts on selecting and warpage in Photoshop
In General, there are several ways to make an ordinary function in Photoshop.And just because you learn a way to do something doesn't mean necessarily is the best way in each situation tampouco.com that in mind, I would like to take some time to discuss the pros and cons of the main ways of doing and feathering selections in Photoshop.
We must of course start this discussion with how to select an area on an image to want to work. After all, if nothing is selected, or if your entire image is, there's nothing worth and nothing to talk about this week. General selection techniques fall into two main categories: regular selections and masks.The loop and the magic wand are examples of regular. selection tools when crawling around an object with the Lasso or click on it with the magic wand, you select it. If your hand is not completely stable or the contrast between the subject and the background is low, your selection may not be as accurate as you want, but you can see what you end up with because the limit of selection is indicated by a line of dots "marching ants" overlay your image.
The basic form of feather a selection made with the Lasso or other regular selection tool is found in the Select menu. Going Select > to > modify > > Feather opens a dialog box asking you the "Feather RADIUS".This is quick and easy, but softens all edges of the same amount. is also a bit difficult to tell just what your selection by now really looks. Everything you see is the "marching ants", covering the area containing pixels at least fifty percent selected. If you apply a filter or to make an adjustment using the resulting selection, you can be in a rude surprise when areas that you expect to totally change not as areas you assumed were out of selection and therefore safe end up getting modification.
Masks do not have always been in Photoshop, although they have been there for some releases now. Its introduction heralded a revolution in the art of making selections. Users can now visually tell how selected or not was any point in your image. A mask is really just a different way to represent a selection.He lives in your document just like any other layer, except that instead of RGB colors is only shades of black and white: a channel, instead of three. any point on a mask layer that is completely white completely is checked. Any point that is pure black is not checked at all. Shades of gray between these two extremes are selected by analogy. Thus, an area that is gray-fifty percent is fifty percent selected and so on.
Each new adjustment layer automatically gets its own layer mask. If you make a selection with the Lasso selection tool or other regular and creates your new adjustment layer with the active selection, Photoshop will automatically transform this selection in corresponding mask layer. You can also add them to image layers by clicking on the small white circle icon (new layer mask) at the bottom of the layers panel with the target layer is selected. Layer groups may also have similarly added masks.Regardless of how you create your layer mask, you can modify it by painting over it with black, white or grayscale. Verify that the mask itself is selected before you paint though, or else you may end up painting directly on your image. If you screw up your image by accident, just use the history panel to undo it. As long as you're actually painting on the mask, your changes are not directly changing the image pixels, so you can adjust your mask infinitely without any loss until you do the right thing. While the effect it has his mask can be seen in the main image window. As I say, that was really a revolution in making selections.
Masks also represent a revolution in how to obtain the selections of feathers. Already mentioned that freely can paint the mask layer to control the degree to which any point is selected or not based on how near it white or black. But you can also use other tools to affect the mask too. The most obvious way of a penalty is to use a mask of obfuscation tools. But you don't need also blur the whole mask. Once a mask is just another layer type, you can use the faithful Lasso or any other regular selection tool to mask itself to limit the affected area, as you would an image layer. No, you cannot make a mask on top of a mask, but you can use regular selection tools and masks together freely.
Back in Photoshop CS4 revolution in broadcast had a second major step forward with the introduction of masks Panel. In the past, although masks allow you to change the appearance of the image without changing the actual pixels image, changes of masks were not themselves non-destructive.I.e. changes put a mask (for example) really changed pixels in the layer mask. of course, you could paint on the mask to effectively undo any changes that you didn't like, but not all changes were easy to undo. If you paint a mask with white, you can switch colors and inks back over the area with black, but if you apply a Gaussian blur to a mask, it really isn't possible re-sharpen it later. You would have dramatically paint the mask existing, or even delete this mask and create a new one. As of CS4, the masks panel lets you apply a blur to a mask that is non-destructive. Move the slider of Feather one-way and mask appears blurred.Slide it back the other way and your turn to be sharp again.Now how cool is that?
Thus, you should always create a mask and worth everything with the slider in masks Panel.Well, probably not.Some changes that you'll never want to undo make them (in some cases) secure with regular selection tools.Selections made with masks, sometimes lend themselves more to painting freehand with low opacity brush so that you can paint progressively in just the right amount of masking in each area.Even these though it may be useful to apply a little warpage masks Panel for when you're done to avoid any brush stokes causing visible borders in the final image. I guess my point is that there is a range of available technical selection and warpage. I often see users of Photoshop to develop the habit of doing private things the same way every time, without stopping to consider whether this way is the best for a given situation.
As I said at the beginning, Photoshop has many ways to do things just because you know a way doesn't mean that you have no need to learn new ways to Adobe presents them also means that when a new way of doing something that comes you should immediately abandon all old ways of doing this because they are obsolete or necessarily bottom. If a quick selection is all you need, go for it but if you really need more control to take advantage of all that Adobe put in the product; this is what is there for.
