Tips

In the summer many photographers set off to visit iconic places. Often these are once-in-a-lifetime trips where you would like to take pictures without hordes of other tourists getting in the way.

With the proliferation of social websites where people upload images for sharing, the ownership and re-use of digital pictures has become an important issue for photographers at all levels. When you publish a digital photo on a website – or provide it on a disk to a friend or customer – it’s wise to protect that image against illegal copying.

Photographers may invest a lot of money in lenses that produce sharp images, but they often fail to capitalise on their investment by not applying sharpening post-capture.

If you’ve used a compact digicam to take digital photos in dim lighting with high ISO settings, your shots will probably be noise-affected. And, even if you’ve used a digital SLR camera, you may find it’s almost as noise prone with long exposures, regardless of the sensitivity setting. To complicate matters, JPEG compression-related artefacts can cause image noise to be more visible, making otherwise great shots unprintable.
