Auto ISO-A new way to shoot

One of the new features on some of a todays cameras is the Auto ISO feature, You have AV where you control the depth of field and the camera sorts out the shutter speed, You have TV where you control the shutter speed and the camera sorts out the aperture, You have Manual where you control the shutter speed and the aperture and now you have Auto ISO where you control the shutter speed and aperture and the camera sorts out the ISO to balance the exposure, On the Nikon D3s you set the camera to Auto ISO in the Shooting menu, Go into the ISO sensitivity settings and set the maximum ISO that you would accept say 5000 and then set the lowest shutter speed that you are comfortable with-say 1/125 and set your aperture, After that all your images will be exposed with the same shutter speed and aperture but the ISO's will change depending on the light, So when would you use this? if you are shooting birds where there are light areas and dark areas you dont have to worry about your exposure as long as you are not concerned that you may have one image with an ISO of 200 and the next where the bird has moved into a dark area and the ISO is 2000, Great when things are changing quickly and you dont really have time to keep an eye on your shutter speed, Try it indoors and notice how the ISO changes are you move the camera around from light areas to dark, Another great feature of a great camera and another string to the wildlife photographers bow

Bio's

David Courtenay, a self taught wildlife and nature photographer, has been capturing images for over 30 years. He has had a passion for wildlife since early childhood and remembers being glued to the television whenever Survival, Wildlife on One and other natural history documentaries were shown. In the 2006 he swapped his established career for the life of a wildlife photographer, such a move demands a measure of uncompromising passion and commitment.

David has travelled extensively throughout Europe as well as spending more than 7 months in India working with local guides and trackers in search of Bengal Tiger, Asian One horned Rhino and Asian Elephant. He has also photographed Wildlife in Australia, Malaysia, Thailand, Sumatra, Africa, Canada and America. Working closely with Conservation companies he tries to raise funds to help Wildlife that has been put on the endangered list by poaching and habitation loss

Martin Dyer has had a passion for avian wildlife since childhood, particularly raptors. Photography was also another keen interest and it was with the specific availability and control of the whole process that digital offers that Martin was then able to combine the two in 2003. Based in the UK, Martin is a regular visitor to Scotland, specifically the Isle of Mull to watch the Eagles resident there. Other trips to Europe and around the UK are usually part of Martin’s agenda in a typical year.

However, as a firm believer on making the most of the local patch, Martin has spent a lot of time and hard work creating a wildlife garden which is reaping the rewards with many new species and varieties of wildlife. A keen member of a number of wildlife photographic groups, Martin is keen to expand his portfolio into other areas of wildlife, and has already established a wide portfolio of images of fungi.
