Just for a ratio this is obviously not needed since the same object is used in the image and as object for comparison.īTW: Starting from "formats" like 24mm x 36mm film or digital sensor is not a good idea. In case you really need a "standard" as used in science and technology you need to contact your government's institute of standards. For 3D objects you may not want to know :-) If you shoot 2D objects at an angle you need to apply geometric corrections for the distance and lens aberrations. For enhanced precision you may have to control minor parameters as well. The magnification is obviously the same for the image without the ruler. The ratio of the (ruler image)/(ruler) is the magnification or reduction. If both images are printed in the same way you can just measure the size of the scale on the ruler in the image by using the same ruler you used for shooting. Shoot a flat object at a right angle and make two exposures - one with a ruler and one just of your object. John you can just measure the magnification factor. Just some further thoughts to offer, I guess. But I also considered that if I extract an element and take its ratio, in pixels, to the total file size and then compare that to the print (adjusted for the print dpi) that that may be a more accurate representation. I actually came up with the traditional method last and thought it might be the most defensible. As in my example above, assuming nothing changed and the world was perfect-as were lenses, sensors etc-the 10mp capture and the 20mp or maybe a 100mp camera in this perfect world (think no limits in lens resolution, noise, pixel densities and all that technical baggage), would you still consider the magnification from each of these 24x36 sensors the same on that 8x12 print? The physical capture/file isn't the same size to start with-but film was always the same size!?! ![]() * Overexposure - (Photography): Definitionīacklinks: Download Quit Smoking Pro 1.JDM, this was actually my last thought in the process although I have been a film photographer for over 30 years-you would think it would have been the first thought!
