This is so easy. Lets begin with what you need first: 1. A decent colour printer. I use an epson stylus d120 2. Photoshop cs2 or 3. 3. A digital camera with resolution more than 5mpx. Here we go! I was going to a steam fare, where the main thing that peeps get excited about is steam traction engines, cars, engineering and such the like. I downloaded LOTS of LARGE pictures of steam traction engines. I then edited them so that they looked like watercolors. It is EASY to create extremely realistic looking pictures with photoshop. Make them vivid - the brighter the better eg make the reds RED. People like bright colours - not boring dark looking pictures. Print them off. I had bought 100 cheap frames at £2 each. I then printed 10 different images of traction engines, 10 of each, 100 in total. I use a bulk ink system - ciss so ink is pretty cheap. All pictures had a custom signature at the bottom with a number from 1 to 50, and advertised as 'limited edition'. Obviously you cannot advertise them as 'hand painted' but you can advertise them as 'hand crafted' by a local artist (me). I printed some postcard sized pictures too. Sold the A4 size pics for £10 each. With diesel costs (to travel the 150 miles round trip), stall cost £25, materials, I made £490 profit. Any spare pics are saved (for another steam fare) and I took some orders for pictures of engines that had sold out. You can do this with ANYTHING - football matches (photographs taken of the ground etc.), car rallies - the limit is your imagination! Why not take some pics of the local area at and sell them at a car boot? Anyway, thats my two penneth for today.
