![]() Then you move off to the edge and you bring it back to the starting point. I find it works if you go to a point like that. Let's start here at the bottom right and just draw around here. I'm going to use that same Smart Lasso tool. If you just mess up a little bit that it takes out too big of a piece you can Undo and try that section again which is why it's important to do it in small sections so that you could easily Undo. You can see here that you've really got to be careful. You can see I can grab another piece there and continue to remove. It's going to ask to convert to a png like before. Still not perfect but it's a little bit better and I can't do multiple selections so if I wanted to keep going I need to delete this section here. So a little zoomed in makes a big difference. So let's zoom in part of the way and let's just try to do it now. Now the more you zoom in the better it works. But you could see here it doesn't do a good job around some corners and things. Smart Lasso gives you this red outline here and you could outline close to the edge like that and then say grab a section like this and it kind of works. Since you could only make one selection at a time in Preview you can't just keep adding to it or anything like that. Lasso means I need to zoom in really closely and then carefully trace the outline here. Now the two tools that will work are Lasso Selection and Smart Lasso. So I'm going to, instead, use one of these tools. If I try to use that same tool it's going to grab some of it but you could see before I even get close to grabbing all of it it's grabbing part of the subject. So I've got this more complex background. Now I've got the background removed and I have a transparent image with a subject on it.īut here's an example where it won't really work that well at all. You could get a little more detailed if you want, like that. Delete that section and delete this section as well. I'm going to do the same thing here and get it to just the right point where it's good enough. I still have the blue here behind the glasses. Now because I'm working in a jpeg image it's going to ask to convert this to a png, something it can actually edit. So I'm going to now hit Delete to delete the background. I can actually get to a point where I've selected all of the background and it has left the subject there. I'm going to select the tool and then click and drag and as I drag more and more of the background is going to be included. But here, with a solid background, it might work well enough. In most cases it wouldn't work because the background is too complex. ![]() The second one is Instant Alpha which seems to be exactly what we want. I'm going to use the Markup Tools here and I only have two options here for selections. So I've opened up the first image here in Preview and this should be the easiest one to handle because it's a very solid blue background. But let's look at how to use Preview to do this anyway because sometimes it's better to be able to do this even imperfectly rather than not being able to do it at all. But the tools it has aren't as well suited for this as the professional apps. Now you can use the Preview App that comes with your Mac to do this as well.
