Imagine you are planning an online purchase, one of the joint most important swaying factors will be a products image - the other is usually the cost. There are plenty of examples of bad shop photography on Etsy - heck, just check this one that I took back in November 2011 - It was sadly one of the 'better' images that actually made it into the shop.
What you will need
- Make sure your camera is on manual settings rather than automatic
- Adjust your ISO settings to the lowest possible - I use 100
- If possible adjust your exposure compensation - look through the lens and adjust the compensation until what you see onscreen is similar to what you can actually see
- Adjust white balance - focus the camera on the white background, adjust the white balance until what you see onscreen is a true white. There are cameras that allow you to take a photograph of the white background and will automatically adjust the settings to achieve a 'true' white - sadly mine has to be done the old fashioned way.
- Turn on macro settings - usually this is a silhouette of a flower
- Turn off the flash
