Tips for taking photos with your device• Don’t use the zoom. Step up or back

away from the subject• Lots of light, but no shine (reflection)

– Shade subject if that’s helpful• Allow the camera to focus before

snapping the picture– If you’re looking a subject on multiple

planes, adjust the subject if you’re having trouble focusing or provide a background

• Some cameras have a macro feature

Apps to help with photos

• Camera Plus to adjust light exposure• ProCapture for panoramas on android• ShakeIt and Hipstamatic for iPhone

General tips• Photos should be IN FOCUS and

provide some information, just like a normal sample– Google for more specific advice– The specialist will also tell you if it’s not

good enough!
