For a photographer brought up on steam powered film cameras, modern day DSLRs seem like science fiction to me. Fifteen years ago, camera functions were limited by the number dials, buttons and levers that could be built into the body. The modern digital camera discards that limitation by the inclusion of a menu system that add a huge range of enhancing features to it. Today we are going to take a brief look at some of the goodies that may be buried deep inside your cameras interface.
1. The Intervalometer
Drop this word into a conversation and people might think you work in a nuclear science lab. The reality is a little more prosaic. By now you would have seen at least one of the many time lapse movies doing the rounds of the internet. To create these, images need to be taken at regular intervals over a period of time. This is what the intervalometer does. You set the time gap between images, the total number of images you wish to shoot and off you go. Although available as an external remote control, many modern cameras do in fact have at least a basic version built in.

2. Manual White Balance
Another often concealed function is the ability to set your own custom white balance. This is particularly useful if you are shooting people under a controlled lighting condition as the white balance will not be influenced by any the color of the model’s clothes. Generally setting a manual white balance is as simple as photographing a piece of white card under the lighting conditions you will be shooting in.
3. Custom Controls
Because DSLRs have so many different functions, it can be a real bore having to constantly set them for different types of shoots. For this reason most cameras have a facility to enable you to create custom presets based on different shooting styles. Things that can often be set in a custom configuration include, metering and autofocus modes, file types, sizes and resolution, white balance, ISO and program modes. Once set up, usually there is a simple button combination used to quickly access each configuration.
4. Mirror Lock-Up
This is a very useful and highly underrated function that is often buried deep inside a menu’s hierarchy. The primary reason to use it, is to eliminate mirror slap. This is not a form of reflective self abuse but instead a problem where when the mirror flips up during a shot and causes vibrations that can that can lower image quality. When you engage mirror lock-up, the first time you press the shutter button, the mirror moves up and out of way. The second press takes the actual image and returns the mirror to its down position. You should always consider using mirror lock-up when taking long exposures on a tripod.

5. Spot Metering
Another very useful function spot metering takes an exposure reading from just a small central section of the image, usually around 5% of the entire frame This is particularly useful when shooting in difficult lighting conditions for example a bird flying in a bright bland sky. By taking an exposure reading from just the bird, you will ensure that is is well exposed rather than the whole image under exposed. Some cameras take this a step further by allowing you to define the percentage area that is metered.
6. In-Camera Copyrighting
This is a particularly useful function for people that post images to the internet. Again often buried away deep in the menu system is the ability to embed a copyright notice to the image’s EXIF data. Generally this is in the form of “Copyright (artist name and year) and will be automatically added to any shot taken. It is very useful if you are sending images straight out of camera or if you often forget to embed copyright information in post production.
7. Firmware Upgrade
Manufacturers sometimes improve or indeed add functions to camera via a firmware update. Firmware is simply the computer code embedded into the camera and tells it what how to work. Although you may be nervous about updating your firmware, it is in practice a simple task. Firstly check your current firmware, usually in the about section of the menu hierarchy. Then go to the manufacturers support pages and check what the most up to date firmware is. Installation is usually down by downloading the firmware to a formatted memory card and putting it into your camera. The manufacturers will have detailed instructions on how to do it. Firmware upgrades have been known to add major extra functions to cameras such as higher resolution video modes or faster more accurate autofocus.

Modern cameras have so many different functions, it is difficult to keep up with their capabilities. Its well worth making sure you download the latest manuals for your camera and spending an evening looking through exactly what you are missing deep in those menus.
