here I was in Amboy, California, and I saw this nice neon sign in. I shot it through a broken window that was in a gas station. That's right nearer, but I was unable to get the neon sign in the distance in the broken part of the glass that's close to me, really sharp. At the same time. I was just too close to the glass, so I shot two shots. I just moved my focus ring to get the area in the distance, shot it and then move the focus ring to get the glass sharp and shot it. Well, I'd like to combine those two together, so I'm going to select the two images. I'm gonna choose tools, photo shop load files into Photoshopped layers, and that should end up stacking the two images, so I get a single document with two layers. Next, I'm going to select both layers, and I'm going to go to the edit menu in Choose Auto Blend layers when I choose auto blend layers. If I use the setting in here that's called stack images, then what it's going to do is it's gonna compare those layers, and it's going to ...
if it finds two layers in one of them is sharper than the other in a particular area, it's going to keep the sharper version. And so therefore, if I have an area that's autofocus in one shot and in focus in the other, when it compares those two, it will keep the air that's and focus. And so all you need to do is click. OK, and now if I look at my results, we have sharp glass and we have a sharp neon sign as well, and that could be known as focus. Stacking is one way to think of it, and this is something that's more critical to do as you magnify things mawr. So if you end up doing macro photography of really small objects like flowers, and you want to get the entire depth of the object to be sharp, well, the more you magnify something the narrow where the depth of field is that you get so you're gonna end up with a lot of auto focus areas. And so if you take more than one shot, you can combine them using this technique to get everything sharp. Just be careful, because if you don't, um, adjust the focus. A small amount between shots. Instead, you do it too big. You're gonna end up with something like this Here I was in, um, the Galapagos Islands, and I shot this one. Been behind him? You can see another iguana, so I shot it with him and focuses. Well, I have a long lens, though, and I wasn't able to get him both sharp and also have a high enough shutter speed. So if you look here, look at the area in between the two and notice that it's out of focus in this shot and out of focus in this shot. So if I were to try the same technique on those two images, all I have to do is select the two. And in this case, I was shooting. Ah, handheld. And if I turn off the top layer, watch the iguana in the back and you seem shift down and to the left, they're not aligned. I could go to the edit menu and choose Ottawa line layers. But when it comes to images that have auto focus areas, it will often not be ableto handle it very well. Let's see if it did. Yeah, that's not bad. Older versions of Photoshopped wouldn't be able to handle that. Then I can choose auto blend layers, but the end result is gonna look odd because it's going to be sharp. Then it goes blurry and ago sharp again, and so that's not really a usable result here. So that's just means Be careful when you're doing multiple shots. It doesn't mean you just need to shots. In many instances, you might need 357 Who knows how many in order to get that full range and focus better to take too many pictures than not enough.
