I played with a few digital drawing/doodling/sketching application on my iPad. One which seems favoured by a few artists certainly demonstrated some real merit. As you play with it for the first time, you find that fingers and capacitive pens do interesting things;it is almost controllable. The fingers and styli generate swirly coloured lines and non-specific shapes. It is almost like magic, if you don't think about the amazing technology that allows all of it to show up. This playtime is quite seductive.
It doesn't take long for the seduction to lead you to interesting-looking purpose made pencils. Pencils and computer tablets? You might well ask. They let you take all sorts of fascinating actions according to the information, they allow you to manually [digitally] sketch, soften lines and work with the colours. You are urged, "BUY NOW". These pencils can even be purchased on a well known web seller's web site. Eeeeek! One pencil, on the website, (it shows a brown one) costs the princely sum of £49 (sterling). Replacement capacitive rubber tips exclusively for the pens, (top tip and bottom tip) are £8 a pair. I have not looked at the selling prices of pens on the app's own site. For one pen that is some price, plus maintenance. You will not be surprised to hear, I have decided I am not that serious an artist.
I have bought an A4 pad of general drawing paper. I did not need to buy lead pencils, I have various grades, I have coloured ones too. So far, I have not had the urge or inspiration to open up the pad of paper and draw anything. Perverse or what!
