So far I have established:
- he uses the Brushes app on his iPad
- Hockney's people state that to avoid pixellation as the size of the print increases, they use a new piece of software which allows prints in a much larger format.
|Brushes Viewer app website - also available as an Apple app|
You can open your .brushes paintings in Brushes Viewer, a free application for Mac OS X. Brushes Viewer allows you to replay your paintings stroke for stroke, export them at very high resolutions (up to 1920 x 2880), and even export them as QuickTime movies.
- Use Brushes Viewer to export iPad sketch at 5X the native size (using the TIFF format) which produces a large file
- Import to Photoshop Elements and touch up imperfections (eg unpainted spots)
- Select Image/Resize/Image Size
- Unselect resample image box
- Type 300 in the resolution box (which changes the file to a higher resolution ie 300dpi which is what is usually required for professional printing) but creates a much smaller image
- Select resample image box
- Check you have the units correct for the size of image you want (eg inches or cm)
- Type in the size of the image you require (eg 20 inches high) - and PS Elements resamples it to create a new large image @300 dpi and keeps the aspect ratio in proportion so long as you also have the "constrain proportions" box checked
- Also make sure that the Bicubic Smoother is selected (option just below the resample command) as this is the best option when enlarging images.
I followed all the instructions except for the Brushes viewer bit at the beginning as I already had the digital sketch on my iMac.
Now can anyone improve on that as a method of enlarging digital sketches created on an iPad?
Any queries? Any suggestions? Any recommendations?
PS Two more posts today related to the Hockney Exhibition
- Book review: A Yorkshire Sketchbook by David Hockney on Making A Mark reviews
- Hockney: sketchbooks, iPad sketching and the Yosemite Valley on The Art of the Landscape This is the post which triggered this post - because I wanted to know how Hockney is creating the very large images from the iPad.
