Puzzling Prizmo I was slightly puzzled when I launched Prizmo because it required me either to open an existing Prizmo document from iCloud or my Mac, but of course I didn't have any Prizmo. Prizmo Go lets you quickly grab text with the camera. After text is recognized in a blink of an eye, you can interact with it in many useful ways. Or just send it to other apps. And if you've got a Mac, you can even copy/paste it there (.). No more retyping. Download the latest version of Prizmo for Mac. Document scanning utility for your digital camera. Prizmo is similar to a scanner in that it can capture any. Prizmo 4.0.4 for Mac is available as a free download on our application library. This Mac download was checked by our antivirus and was rated as virus free. This program was developed to work on Mac OS X 10.10 or later.

All you need to do to extract the document from the photograph is select the area of the image where it appears, giving the selection tool the correct orientation. Loading an image is as easy as dragging and dropping the file into the program's interface.
Prizmo can make some additional adjustments to correct the effect that the camera lens has had on the document, color correction being one example. Also, this tool supports more than 40 different languages and also is supported by iCloud, which allows you to automatically send your texts to your online Apple storage.
The program works with any device that has a camera, including the iPhone, the iPad, and digital cameras, plus scanners that are connected to the same Wi-Fi network as the device where Prizmo is installed.

This review is all about using a digital camera for a purpose it was never intended for.
Since taking on a new Mac with Snow Leopard operating system I sadly found that my marvellous image/text scanner does not work due to a lack of a suitable driver.
Now, since taking on Prizmo for Mac I can scan documents as well as perform OCR to file away the editable texts.
Then I found other but possibly less useful functions tucked away in Prizmo: curvature and perspective correction.
Let’s start with the OCR function. I made three handheld shots with my trusty Sony compact digicam, saved as JPEGs: one of a photocopied magazine article; a page from an early book of comic poetry; and finally, a page of tightly packed from a book of mine on collectable cameras.
The photocopy image was imported into Prizmo. First task was to locate the grid corners, the area in which the desired text was located; so I tapped the button Full Grid … this can square up an image that may be off level.
At this point I tapped the OCR button; by moving the cursor across the page I could preview the recognised text; following this I saved the OCR scan and could do this as a PDF file or as rich text or regular text.
If you’re running the demo version you can assess Prizmo’s capabilities in OCR and view its ability to recognise text — but the demo does not let you save it. Natch!

The result was that I had a text file that was 99 per cent perfect, falling down only where there were line breaks. Spelling? 100 per cent correct!
You may need to work with pages that are less than white in colour or ones that have text in colour. The app’s controls allow you to correct brightness and contrast in the document image or even to reduce its bit depth.
Now to the books
The comic poetry book image showed some curvature from the book not being photographed completely flat. No probs! Any bends were corrected in Prizmo.
The other book page was a bit more challenging but, by squaring it up and adjusting brightness I managed to make an OCR scan that gave me 99 per cent correct, readable text.

The app is handy for squaring up images but frankly is little better than Photoshop’s tools. But if you ain’t got Photoshop….

Comment
I found that correcting the squareness was the main element in achieving successful OCR.
The app is a little erratic in its behaviour: sometimes an image would load upside down and then, on occasions, the preview would appear upside down or sideways on the preview screen.
To assess its OCR talents I ran the text images through a dedicated OCR Program — ABBYY FineReader 5 Sprint Plus — and found that on most images Prizmo performed better. Nuff said!
