Photography question, whats macro and infinite focus, what does VGA stand for and do?
You really need to do a short course on photography to understand what to do with all these things, but here’s what they mean: Macro is for close-up photography. In this mode, the camera will focus from about 6 inches to 3 feet (depending on the camera) Infinite focus is for photographing things a long way away. Film cameras with a standard lens tend to reach infinity for things more than 70 feet away. With compact digital cameras it is about 30 feet. With professional cameras it is further. VGA stands for video graphics array. It means 640 x 480 pixels with 256 colours. It was the standard for the first computer monitors to show fairly realistic photographs – but pretty tame by today’s standards. Compact digital cameras often use this mode for video clips. An automatic camera measures that the correct amount of light falls on the film or CCD array. Normal metering mode is based on the total amount of light coming into the camera. Spot metering mode uses the light intensity for that pa
Macro focus allows the camera to record images on the sensor the same size (1:1) as they are in real life, in otherwords: Macro allows you take close-up photos of very small objects. Infinity focus is just that, focused everywhere from around 7-8m to infinity – no focus is applied and the lens is focused at its max range. Metering refers to where the camera measures how bright the scene is from and how much light to allow onto the sensor. ‘Normal’ probably uses the whole sensor and takes an average reading of how bright the scene is and exposes for that. ‘Spot’ uses a small dot in the middle of the sensor to measure the light. You would use this if you are taking a photograph of someone against a bright background, for example, to make sure the camera exposes for the darker person alone. VGA is completely different – it stands for Video Graphics Array and was basically a screen resolution: very small by today’s monitor standards at 640 x 480 pixels but pretty good if thats on a 2.5″ di
