I have always found that one of the toughest parts about working in Photoshop is selecting parts of an image for deletion or enhancement. When I first started using Photoshop many years ago, I thought the only way to accurately make complicated selections, ones that aren’t simple rectangles or ovals, was to use the polygonal lasso tool. If you’ve ever done this, then you know it can sometimes get very tedious.
An easier way to make a selection is by using Quick Mask in Photoshop.
With an image file open, you enter Quick Mask mode by clicking the Quick Mask button near the bottom of your tools pallette, or by hitting ‘q’ on your keyboard. It will appear that nothing has happened, but you will have in fact been magically transported into the rose-coloured world of the Quick Mask.
The simplest and easiest way to start working in this mode is to choose a brush, set your foreground color to black and start painting away. You will immediately notice that as you paint, even though your foreground colour is set to black, everything you brush over will come out reddish. Don’t worry. You want this to happen.
To use an analogy, when you are painting a room, you use masking tape to cover all the bits you don’t want to get covered in your lovely shade of eggshell mocha. Well, that’s the same thing you’re doing here in Quick Mask. Everything you cover with your reddish “masking tape” will be protected from whatever it is you’re going to do with the image. The idea is that Photoshop will “select” everything except what you have painted in red.
Once you’ve painted over all the places you want “protected”, simply click the Quick Mask button again, or type ‘q’ on your keyboard. Everything except what you just painted over will be encircled by marching ants indicating it’s been selected.
If this is what you want, then just move on from here, deleting or enhancing the selected area. Otherwise, you can go back into Quick Mask mode again and make adjustments to your mask.
What if you want to enhance, delete or otherwise change the area you painted over, rather than have that area masked? Easy as pie. Once you’re out of Quick Mask mode, select the inverse of what is currently selected by choosing Select->Inverse in the menus or hitting the CTRL-Shift-I keyboard shortcut or âŒ˜-Shift-I on a Mac. (That’s the letter that comes after H, not the number 1)
Here are a few tips:
- Painting with black as your foreground colour applies the mask to an area
- Painting with white erases mask from an area
- You can use other tools (eg: gradient) to create a mask
- Try changing the hardness of a brush when creating a mask
There are lots of other ways to select stuff in Photoshop. Each has its own uses. I’ll explore some of them in future articles.
What’s your go-to method for selecting stuff? The one you always try first. Is it one of the lasso tools? Color range?
