Recently I came across a very helpful scanning tool. If you are a PC user you can download free software from Microsoft to automatically align and compose multiple scans.
This article is still helpful in theory. However the free software app is much more reliable ,I find, than ‘eyeballing it’. Here’s the current download address. The The app is called Image Composite Editor:
Sooner or later almost every artist will want to copy their work. Often a good digital camera with a great lens will do the trick shooting in diffused lighting.
However, sometime it may be more convenient to use your digital scanner to scan in the image of the print. The plus side with scanning as opposed to camera shots is that you will get an even, flat and highly detailed image. The down side is that you have to keep an eye on your scanner’s settings (are you in professional mode, what’s your dpi, etc.) and you may get too much detail ( like markings on the back of your canvas showing through). Although this is usually not a huge problem.
Once again I must say that these are the methods I use and someone else may get better results with their own techniques.
So let’s say your painting or art work is just a bit too large for your scanner’s surface. This is where stitching comes in handy.
I use Corel Photopaint and it does the trick. Other software likely offers similar options.
First you want to scan in both halves of the painting. Doing one side at a time. I use the settings on my scanner software for Photo at 300dpi and high quality prints/posters. Preview and then scan the image. If given the option to use a mask (a selective, dashed -line frame box) when choosing the area to be scan then choose to scan a hair’s width away from the outer edges of the area to be scanned. Let me clarify. Do not bring the border of the selection box to the very outer edge of the painting preview. Some scanners experience a little drop-off in this zone and you may get a slightly darker sliver of the image that will affect the quality of your final print. I’m speaking of what you see in the selected preview of the glass on the actual scanner. So you could accommodate for this drop-off by allowing a border area left blank outside of the painting.
Okay..a picture is worth a thousand words I guess 🙂
The yellow area with the green dashed line is the maximum scan area of the glass. I have the painting positioned just a bit inside of that area. The dark dashed inner line (red arrows) is the area in which the software sees to scan. Notice I have that area narrowed a bit cutting the wookie’s face in half and not going all the way to the edge. Okay..let’s move right along.
By now you should have two separate images of high quality which you can open up in Photopaint.
Next you’ll want to crop one of the images to a smaller selection so you’ll have less image to match up and blend (above image). Do leave a little area of overlap as you can see i did for Han Solo’s gun.
Above: The cropped image.
Above: Under Image select ‘Stitch’
Above: Now select ‘Add All’
A new screen appears and using the select pointer tool you can ‘grab’ one of the images and match and blend. I have the blend image setting at 5.
Above: A close-up view ( you can zoom in to get a better match up) shows where the two images blend. Now just hit enter and a new solid image will be created from which you can manipulate or save as different files and sizes.
That’s about it. Hope you find that helpful. Check out my design page for further designs. Thanks for stopping by!
