Am doing this for work and its stretching my job description a bit, as Im by no means a photographer, and I am getting a wee bit confused! I have taken several photos from a viewpoint in the rural landscape over 180deg using a 50mm lens. Ive then had the negatives scanned in, and digitally stitched them together to make a photomontage. I have a wireline model of this view set the same as a 50mm lens with a 45 degree angle of view which fits across the length of A3 paper. I have to set up the page so that the photomontage is under the wireline and matches exactly. Technically the wireline should be altered to fit the photo, however Im doing it the other way round (cos Im blonde!), and to match the photomontage to the wireline I have had to zoom in. Now, this is my question If the wireline is set at a 50mm zoom and a 45 deg angle of view, if I manipulate the photomontage by zooming and cropping to match exactly the wireline does this mean that the photo does not truly represent a 50mm view anymore? Surely it depends on what size you get the photo developed/scanned at? And that the 50mm view would not be altered it just would be a narrower angle of view? I am currently being questioned over this and Ive got confused! There is also a viewing distance calculation, which is how far you put the paper in front of your eyes to get a representative view, which takes into account the angle of view and length of image on the paper. I can work this out, but of course it is only valid if the image is correct. If any of that makes sense any advice would be gratefully received!
