- Print publications require high quality 300 D.P.I. But 200 D.P.I. will provide very acceptable quality for all but the most demanding gallery exhibitions.
- Aperture Priority (Av): You choose the aperture setting and the camera choses the best shutter speed.
- Shutter Priority (Tv): you set the shutter speed and the camera chooses the aperture.
- big numbers mean big zoom, small numbers mean wider angles of view
- A 50mm lens will record a natural image with the least lens distortion caused by wide angles and no zoom. It most closely records what your eyes see
- A mirror reflects light from the lens to the viewfinder (hence SLR = Single Lens Reflex). When you hit the shutter release the mirror swings out of the way and gives that signature clunk noise
- A tripod is usually needed when your shutter speed drops below 1/60 or when using longer telephoto lenses
- The further or higher above the camera lens the less likely you will be to get the red reflection
- bounce the flash off walls and ceilings to give a softer light and less harsh shadows
- Be careful when the walls are colored as the flash will pick up color and tint your subject
- A diffuser is a good companion to a powerful flash. It's a translucent cover that softens the light from a flash
TIPS:
- When reviewing images zoom in to check the image is still sharp when viewed at full size
- Cable release extension cord is very expensive. If your camera uses 2.5mm jack plugs, buy 'step up' and 'step down' converters to 3.5mm from any electronic parts store. You can then purchase extension cable for regular stereo equipment instead of the expensive proprietary branded cable. I found 6 meters for a dollar!
