First definitions from microscopic: so small as to be invisible or indistinct without the use of the microscope : microscopic organisms. Compare macroscopic. macroscopic: visible to the naked eye. Compare microscopic (def 1). The things we photograph with macro lenses are still large enough to be seen with the naked eye (roughly cm or inch ...


You are correct that the term "macro" means large scale (e.g. macroeconomics), however its use in photography is relative to microphotography, that is imaging using microscopes. The tradition definition of a macro lens is one that can achieve a 1:1 magnification, which means the image projected onto the recording medium is life size. So for a common APS-C ...


This question is tagged "history" so, some history -- Photographs (of course) don't have to be literal captures of a scene. Plenty of photographers (past and present) have manipulated the image to reflect their feelings about the subject (or other stuff). Pre-digital (and really, before desktop computer image editing -- which pre-dates pure digital ...


The following is probably not entirely accurate, but I will try to highlight what I think the main differences are. Also, keep in mind that most of the names used above are umbrella terms for whole families of processes that might differ significantly within one family. I think photogravure and circuit etching can be seen as somewhat similar with respect to ...


If you put the same lens at the same aperture on a full frame and APS-H camera, you will need to get closer to the subject with the full frame to have the subject the same size. As such, the depth of field in the resultant image will be shallower. If you take both shots from the spot the depth of field will be identical, but the subject will be smaller on ...
