<p>[QUOTE="dougsmit, post: 2228275, member: 19463"]Try as I might, I have been unable to duplicate images I made of coins several years ago. Some of the new ones come out better and some worse. The images record the camera and lens used as well as aperture but it would have required my recording the exact lighting used and I did not then (still don't for that matter). Lighting is very much a performance art and every little wiggle of a coin changes results just like it does with the violinist's bow that separates one performance of a middle school orchestra from another. Professionals are more consistent than I am. </p><p><br /></p><p>I do agree that macro primes are much better corrected than consumer grade zooms. I am just discovering the things that can be done in the inner levels of RAW software (I use DPP4 but there are many expensive ones that some people swear by. Are color aberrations postprocessed equal to those avoided with a better lens? I guarantee neither method makes as much difference as a solid, vibration free mount. I am certain that I am incapable of producing a pair of images that fairly isolates the contribution of one variable. I also know that I can produce images at least as good as I need for the coins I can afford. I am reshooting some of my favorite coins and see some improved but most just different. Coin photography is a side hobby I have found not much cheaper than collecting since I have been known to buy a coin to see if I am good enough to take a good photo of it. Canon has upgraded my best camera twice since I bought one. At least I have avoided chasing that rabbit down his hole.[/QUOTE]</p><p><br /></p>
