![]() ![]() Well that was day one, and I have taken a lot of photographs since then. In fact, I was so surprised on the first shooting day of this project, that when I saw the speed with which Helicon ripped through stacks and saw the quality of the initial few batches of simple stacks, I immediately called my friend Mike, another Zerene guy but several time zones to my left, and yelled down the line, “Mike, Just saw the first few outputs from this Helicon stacking software and it is nothing like what I was expecting.” He responded by muttering something that might have been a friendly “cheerio”, but which sounded more like an unambiguous death threat, before hanging up on me, as he does every time I call at 3AM. This is the kind of healthy competition that keeps everyone on their toes. That is good for us and it is good for Zerene. Helicon has come a long way since I first tried it out. So, I was surprised but excited to see that there was some serious competition, after all. That was quite some time ago and there weren’t that many people that I knew using anything but Zerene. That was, after all, why I chose Zerene Stacker as my stacking software when it was time for me to get serious about my work. I came into it expecting to find Zerene a better product in every way. This is a web page that discusses this approach.This has been a long but enjoyable process. I just thought someone at your company may want to consider this approach, and discuss it further. I think this process could have a lot of potential to build models of high magnification subjects. These precision steps can output height information because only an incredibly narrow band of the subject is in focus during any one exposure. The pros use microscope optics, and computer controlled step mechanisms to capture incredible 2D images. Some of my final images took 70 photos to achieve sharp focus in the entire picture, and my magnification level is still at an amateur level. There is no way that I have heard of to capture more than a sliver of a higher magnification subject without stacking. There is very likely distortion in this process, as either your camera has to move our your have to shift your focus ring in tiny increments to capture macro subjects. Helicon Focus has a unique ability, in addition to focus stacking photos, it can generate a 3D file from the data from only a single perspective. I would envision that this technology could make it possible to describe the object with much fewer camera positions. I wonder if there is expertise here that could address this technology, and if in the future this might be a possible solution for building 3D macro surfaces. I have seen hand held 3D scanners that record information from various directions of the subject, and are then able to reconstruct a complete representation by stitching together the multiple scanner passes. It has an obvious limitation, in that is only able to process information from one direction, but the information seems like it would have some very accurate topographical information as the different narrow layers are processed.that are in sharp focus. I wonder if these processes are at all similar, and if the Helicon Focus output could some how be used to build complete 3D information. I can not help but notice that part of 3DF Zephyr also processes something called Depth Map. Using the areas of the frame that are in sharp focus it is able to build the 3D information using a Depth map stacking process. I heard about a photo stacking software called Helicon Focus that can output a 3D file from one stack of photos. ![]() I have recently joined a forum that specializes in macro photography. ![]()
