This has been driving me mad for the past 2 hours. I am stuck in a course where I need to create a 1 pixel brush. Every time I define a brush preset, it doesn't work as expected. Anti aliasing is turned off in most options. I then use the magic wand (I tried the square marquee select as well, doesn't work). Then to Edit -> Define Brush Preset. The Brush says 1 pixel but it doesn't look like a square but rather a square with an arch on the bottom right. It worked fine earlier, a square 1 pixel brush, suddenly it does not. I have reset Photoshop to it's defaults and also Preferences -> General -> Nearest Neighbor.
1 pixel square using the pencil at 1px
Another student had the same problem but somehow resolved it themselves:
Blockquote Hi thanks for the reply! so i tried other brushes and they work. the pencil tool even with another 1 pix brush does 4 pixels and they are about 50 percent opacity. i will delete the brushes i made and try again.
Thank you for taking the time to read my problem, any help is deeply appreciated. Apologies for being a noob :(
The instructor did it without any problems
The reason to use the brush is I need to create an 8px horizontally and vertically brush.
EDIT 2 That is the result I get when defining a brush preset of 8 pixels vertically (on the left is the pencil tool, on the right is the brush preset)
