I haven't managed to get much painting done recently so again the blog is suffering but I thought that this presentation from Slideshare was worth sharing.
Nothing new and to a regular artist not rocket science but it is neatly and effectively presented and serves as a great reminder.
I have not yet fully explored this site, all sorts of presentations and I may come back on this one if it seems to have any "artistic" uses or merit. The site may be used by guests to view the presentations (powerpoint style?) but to upload you do need to register, it appears to be free with possible upgrades which are likely to need subscription.
