I found a duplicate post here but with no answers. I looked at this guide from adobe on how to feather edges hoping I'd find an answer but my Feather: option is already at 0 px. I have never had this issue before in photoshop or any other editor, but I also haven't touched any settings since the last time I used it so I have no clue what on to do. The photo, as you can clearly see, is pretty big but even so it shouldn't be coming out feathered. I even went to select -> modify -> feather and set the value to 0.1px but that didn't help.
The Marquee tools and the Lasso tools (as you are showing in your video) can be either aliased or anti-aliased.
Quick Selection Tool doesn't have an option to turn anti-aliasing off.
A quick workaround could be this:
- Make your selection with Quick Selection Tool (or any other way).
- Hit Q to enter Quick Mask Mode.
- Apply Image > Adjustments > Threshold and just keep the Threshold Level at 128.
- Hit Q again to leave Quick Mask Mode.
Now your selection is 1-bit with no anti-aliasing.
