Sketchbook scan tips

Rhomany’s Realm of Urban Sketchers Stoke-on-Trent recently asked me this great question: “Can you give us any tips on scanning/photographing your sketches for sharing online?”  I thought it was worth taking some time to answer.

With most mobile smart phones, it’s straightforward enough to take a great photo, crop and edit it and post on line. Here’s an example from a few years ago, when I began with indoor sketching, the softies option. I took this pic with my camera and although it looks ok, it doesn’t really engage the viewer with the content of the sketch.

I’m sure that most people can do a much better job than this with their phones and the wide range of editing tools available but over the last few years, I’ve found I get a fresher and more consistent image by scanning the sketch.

I keep a record of most of my sketches and file them by date and location. I scan them as a jpeg at a medium resolution (300dpi),  on a six year old Canon MG5250 scanner/printer.

When I place the sketch book on the scanner, I press the lid down to flatten the spine so as to get an even scan up to the binding otherwise the edges are blurred. This works up to within 1cm of the spine and it’s worth bearing in mind to keep any penwork away from the spine when sketching. Pressing down also helps flatten bumpy page surfaces.

Here’s the unedited scan of the sketch. You can see the blurred lettering where the spine can’t quite lie flat.

The next thing to do is to crop the image and get rid of any unwanted parts in Photoshop or Microsoft Picture Editor.

I’ve cropped the image below but the lettering still looks fuzzy so I opted to lose it for the shared image and cropped it again.

There are lots of tools for colour corrections but I often end up using the ‘auto-correct’ tools to enhance contrast which lifts the mist from the image.

I add my web address in the image as a reference so when it sails off into the ethers, it retains a reference to my website. I prefer to keep the web address fairly discreet so as not to distract from the sketch. I also save the image at a lower resolution so it looks fine on screen but isn’t sharp enough to print.

This is a simplified description of my editing and like all these things, I could go into it in more detail, so any questions, just ask. That said – I may not know the answer!

I have all my street drawings scanned, colour corrected and printed professionally by Smith York Fine Art Printers as it gets quite complex.

Although this process takes up a bit of time, it’s an organised way to keep your sketches so you can find them easily and it’s also a record in case your sketchbook gets drenched in rain or coffee or your cat decides to help out…
