With the camera on aperture priority or manual choose an aperture about halfway in its range. If your camera can take a lens hood, use it, if not, shade the lens with a bit of card. Do not use the wide angle end of the lens, as that can cause barrel distortion, but rather use a medium to long tele setting. Attach the camera to the tripod or secure it so it cannot move avoid hand holding it.ДЇrame the painting on the screen or viewfinder taking pains to get it as square as possible and crop it as close as you can if you have a zoom lens, it can do that easily. Avoid using flash, as it can be a bit harsh. Organize plenty of light, especially if you have a small camera with a small sensor as you are less likely to get noise or grain.

Preferably light it with daylight a bright overcast day is best. Set the exposure mode to either aperture priority or manual do not use automatic as it changes the ISO rating. Set the ISO rating to its lowest that gives better tonal quality, and have other settings at standard or high, and noise reduction to low, the quality at either TIFF or RAW (if your camera doesnвЂ™t have these settings, set it to its highest quality JEPG ). Experiment and get to know your camera as well as you can. If your camera doesnвЂ™t do these things you can still probably make it work for you.

The camera should be able to be attached to a tripod and be able to produce TIFF or RAW files and photograph in an aperture priority or a manual mode. SLRs have bigger sensors and in theory give better tonal quality. Somewhere between 5 and 10 megapixels would be fine the bigger the sensor the camera has, the better the result. The better the camera, the better the results. A top end point and shoot or a low end SLR would be adequate but anything other than a telephone should do. It is best to learn to use the camera you have rather than buy something that may be rather expensive, and that you donвЂ™t really need.
