The polygonal lasso tool will draw only straight lines for you, so switching between both for any shapes that have not only straight lines, but some curves, will be the best way to use it. Then I’d press Shift+Backspace to get the Content-Aware Fill up and just click OK. Something that you can use the Lasso tool a lot for is to quickly select an object I want to delete from the frame. A neat trick here would be to switch between the lasso tool and the polygonal lasso tool while making a selection by holding down alt/opt.
You will be absolutely free when using it, thus making it somewhat harder to make precise selections. To freehand draw your selection you will select the lasso tool. The lasso selection tool has a few options. Now, on to the next selection tool in Photoshop. On the top menu line of Photoshop you’ll see the Selection Options Bar. By choosing one of the modes, you’ll be able to make a new selection, adding, subtracting or intersecting with the already existing intersection. Something worth noting here that will be relevant for all the rest of the Photoshop selection tools is the selection options. Thank god those days are behind us, right? Something curious is that apparently it was also used to manually create guidelines. Actually, this is considered to be a legacy tool, left from the days when you had to scan a lot of your work and it was used to repair scanner lines by selecting and duplicating one-pixel rows/columns onto it. You can also use it to make single row pixel selections, as well as single column pixel selections.
It’s a really useful tool, but in the real world most of the things you’ll need selections for won’t be that easy to select. A quick and easy tool to use, especially when selecting oval or square/rectangular shapes. As long as you’ve got the perspective right, that is. It’s actually really good when you’re selecting signs, documents or let’s say windows, doors and other straight forms because it doesn’t have any automation behind it and it might save you a lot of time. It’s designed to select in either elliptical (or circle) and rectangular (or square) shape. You’ll later find that you’ll hardly ever use it. Starting from the top down, the first Photoshop selection tool you’ll encounter is the Marquee tool and its variations.
