The MacBook’s Retina display is a beauty. After looking at this 2560×1600 monitor, I don’t even like my 1080p screen very much. Photos and videos, even low-resolution ones, look great on a Retina display (thanks to OS X’s great extended features). But by far the best thing about it is the text. It’s so sharp and so clear.
Retina doubles the screen resolution. But that doesn’t mean you see more than twice as much on the screen. Even though the resolution on my 13-inch MacBook is 2560×1600, OS X still displays at 1280×800. But when you take a screenshot, your Mac defaults to the screen’s resolution. And let me say, on anything other than a Retina display, that screenshot doesn’t look good.
If you’re taking screenshots to share with colleagues or to upload to a web page, you might want to go back to 1x low resolution. Thanks to a third-party application, you can.
Retinal imaging
This is the interface of RetinaCapture.
This screen has all the options you need.
It allows you to take 1x, 2x or both screenshots. You can save them as PNG or JPEG. When taking a screenshot, you can capture the full screen, the self-timer screen, the selected area, or the window.
Full screen option takes full screen image. After taking the screenshot, you will get a save dialog where you can define the name of the screenshot, the folder and the format.
The timer display option gives you a 10 second countdown.
The selected area option dims the screen and allows you to drag a selection to capture it.
The window capture option is a bit complicated. It pops up a new window asking you to highlight the window you want and then click Select window button. This floating window will not be captured in the screenshot.
Further optimization of the image
If you’ve used Retina 2x screenshots (can’t blame you, they look epic), you might be surprised at the size. Retina screenshots are really heavy. PNG can be larger than 1 MB.
But what if you can’t use 1x resolution because it’s pixelated?
There are two ways I optimize images for online use.
The first is an app called ImageOptim. Open the app and drag the image in. The application removes a lot of unnecessary data from the file while keeping the quality intact. The app doesn’t make a copy, it edits the same image instead. So make sure you have a copy of the original photo if it’s important.
ImageOptim always saves me 25-35% in file size.
Another one is tinypng.com. We talked more about image compression sites here but I use tinypng. It does an amazing job of compressing images by 50-70% with almost no quality loss.
