Bees and some Comments on Camera Automation (Two Photographs)

These bees were taken at 500mm at ISO 800 and F8 (the full-frame equivalent is F16). Natural light means the highlights are natural results of the sun. ISO 800 is a very usable ISO on some of the newer cameras with very little noise. Modern DSLR and some Mirror-less cameras have a huge variety of functions and the ability to automate them. Auto-white balance is standard, especially if you shoot in raw as the white balance can be easily adjusted in post-processing. That said there are times when creating your own white balance or using a preset white balance makes more sense (e.g. under artificial light.) Program Mode where the camera chooses what it considers is the best balance between aperture and shutter speed can be useful for street photography. While shutter speed priority can help with sports, aperture priority gives a great deal of artistic latitude as it lets you choose what is in and out of focus. However in aperture or shutter speed modes, you need to consider what ISO you want to use. For example I want to shoot a bee and stop its motion – 1/500th of a second with image stabilization promises my shot will be sharp but doubling that stops the bee’s wings in motion. To get to 1/1000th of a second and an aperture of F8, I needed an ISO of 800. There is no golden rule here, except that a speed that reflects the length of your lens is more likely to get you a sharp shot. I usually shoot in aperture mode. Higher ISO allows for smaller apertures (F8-16) or greater shutter speed at the expense of noise. Some cameras make it easier than others to change these parameters and it is a thing to consider when buying a camera as to how accessible the functions are to make quick changes.
