Are You Getting Good Value From All your Pixels?
The camera pixel race has not abated, many cameras have pixel counts that are far in excess of what is needed for a high quality print. We receive marketing messages all the time about new and improved cameras. The Nokia Lumia 1020 mobile phone boasts a 41MP sensor. The £17,500 Hasselblad H5D-40 medium format professional camera with lens has a 40MP sensor. This prompts two questions, how many Pixels do we need? and how many are we effectively getting in practice? This talk will focus on the resolution of the human eye and how that translates into how many pixels are really needed for high quality prints.
Having shown how many pixels we need, we will move on to discuss how many pixels worth of resolution we are really getting. Cameras are now being advertised as not having anti-aliasing or low pass filters claiming they will produce more detailed images than from cameras with the same number of pixels with the filter, is this true? The talk will look at the way digital cameras sample images, the need for low pass filters, and whether the effective number of pixels in your pictures is governed more by optical and software considerations, than the number of pixels on your camera’s sensor.
