How to organize photos like a pro: the best way to make sense of your collection Oct 10th 2013, 23:01, by anicholson Is your hard drive heaving with uncatalogued images? Discover the best way to organize photos and stay on top of your growing archive! In this tutorial we’ll show you how to organize photos like the pros by adding copyright information, metadata templates, keywords and much more. When browsing images in Bridge you may have noticed the Metadata tab, which lists useful information about each shot. This is because as well as recording the image and file name, your camera saves metadata, which follows the Exchangeable image file format (EXIF). The literal meaning of metadata is 'data about data', and for digital images the metadata holds key information, such as the date of creation, the make and model of camera and key camera settings. A sub-set of metadata, in a format developed by the International Press Tele-communications Council (IPTC), contains information about the image's creator and copyright. Unlike the camera settings data, which is set at point of capture, IPTC metadata is editable, so it can be set by the photographer or whoever owns the image copyright. Once you've created a metadata template you can even add this information automatically as the image is imported onto your computer's hard drive. Photographers can also add keywords to describe the content of images. These can be general subjects such as events, people and places, but sub-keywords can include birthdays, names, cities etc, and can be used to make finding specific images easier. Once a template or keyword has been appended to an image it stays there, so if the image is sent or saved anywhere new the key information is still available.

This week we thought we’d show how to use a variable ND filter, which you can use to capture amazing motion-blur effects. Unlike an ND grad, a variable ND filter reduces the light across the whole image, and you can twist it to control the amount of filtering – this is what variable means. ND variable filters come in handy for slow water effects or adding motion blur to people, and they're essential in bright conditions. You could even keep a variable ND on your lens all the time, so long as you don't mind losing a stop or two. Here's how to use this versatile filter to get cool motion blur effects on people. How to set up and use a variable ND filter 01 Set up your camera Blurring people walking past a scene requires a slow shutter speed, so you'll need to put your camera on a tripod. Then either use a cable release or the self-timer in order to avoid camera shake. You can also lock up the mirror on your camera to reduce shake even more. Your camera's manual will explain how to do this.   02 Select your settings Attach the variable ND filter to your lens. Try an aperture of f/11 and choose a shutter speed of 1/4 sec. The filter will enable this. Set a low ISO (a higher one or auto ISO will give a faster shutter speed and spoil the effect), and zoom in about halfway if you have a standard zoom lens. Variable NDs can cause banding if you shoot wide-angle.   03 Switch to manual focus You will need to switch to manual focus, and focus where you want to stay sharp – a building as the background, for instance. If you can't see anything because of the filter, focus using Live View and adjust the filter until you get the desired effect. Don't rely on autofocus, as it can struggle to focus through the filter.   04 Block stray light Once you are happy with the focus, it's worth covering the eyepiece to stop stray light getting in (again your manual will explain how), or just cover with your other hand. Then, wait until people pass in front of the background and take the shot. Adjust the shutter speed if people are moving very quickly or slowly.
