There are so many handy tips about obscure Photoshop techniques floating around, that sooner or later, some of the more arcane ones just float off, beyond the reach of memory. Well; my memory, anyway.
The research I do entails a lot of scanning, and of all sorts of materials. Typescripts, books and magazines, and even old faxes that can all take a huge amount of Photoshop tweaking before they yield their textual hearts to the OCR software and become malleable, editable text once more.
I once found a tip that made it really easy to discover the exact angle that an image of a page needed to be rotated by to make it perfectly vertical once more. That was a few years ago, and through lack of use, I forgot the darn thing.
Many trial and error filled hours were spent trying to gauge tiny fractions of a degree of rotation so as to straighten my pictures. What an obstinate waste of time.
Today I was trying to clean up some old notes written by Richard Williams about various animation topics that will form a new series of posts here. Some of the notes had been photocopied at extremely wonky angles to the photocopier, and I thought it would be a good moment to re-learn the beautiful and subtle rotation photoshop technique. I rediscovered it at the Tek-Tips forum (1,354,000 members) that I normally consult for hardware problems, and there’s a huge community of people discussing tech tips about every minute aspect of computing.
You can see it demonstrated below. (all the images get bigger when you click them)
First: Scan your image –
Your typical wonky scan that needs to be rotated. But by how much, exactly? One degree? One and a smidgin?
First you need to get to the Measure Tool. This is not an everyday tool, I suspect from the fact that it’s buried way down a right click submenu, and it’s probably most commonly used for measuring the edges of right angled components. However, it also measures angle, much to my joy.
Dig down by right clicking on the eyedropper tool and you’ll find it.
Drag the Measure tool along the baseline of the text, or whatever it is whose slope you wish to measure. This example shows the very thin line of the Measure tool on the baseline of some type, between the two purple arrows.
O.K. Now click on Image > Rotate Canvas > Arbitrary and Tadaaah!! the angle in degrees is already in the box, awaiting your next click Clockwise or Counter Clockwise….
Accuracy and convenience. Who could ask for more? Just click OK!
Straight up! The grid shows how accurate this method is. To remove the grid press Ctrl and “H”
