CAMERA NOT FOUND ON ANDROID HELICON REMOTE MANUALOf course, as I've mentioned before, it also depends on the subject matter, and of course one can only use a rail with manual focus lenses (assuming automated sequence capture). He basically concludes that in general, subjects at the size of a raisin are at the tipping point between both techniques. Rik Littlefield, the author of the Zerene software, has a nice article dedicated to that ring-versus-rail trade-off, here. Subject matter also makes a big difference, especially occlusions can cause issues (using the correct stacking method also makes a difference, and one can also combine (with) the results from different methods). small jewelry or watch-face detail, a focus-rail setup is often better (because of the much narrower DOF at such magnification factors). That's understandable, given that natural perspective at this shooting distance is probably preserved better by (internal) focusing (smaller change in entrance pupil position). Personally, I prefer the results obtained by focusing the lens rather than using the rail. The magnification is that height divided by 5.0 The image size of 5 cm on the ruler was determined by measuring the number of pixels occupied by 5 cm on the ruler and calculating the percentage of the picture height taken by this 5 cm and multiplying by 2.4 cm to obtain the image height of the 5 cm segment. The image height of the sensor is 4912 pixels and 2.4 cm. CAMERA NOT FOUND ON ANDROID HELICON REMOTE SERIESWith the focusing rail, the magnification is reasonably constant since the object distance of each shot of the series is the same, but when focusing with the lens the distance to each ruler in the series varies. They should be the same, but the magnification is slightly different due to camera placement.įinally, this table shows the magnification of each image in the stacks. Note the artifact on the closest ruler, which was not present on the individual shot of that ruler:įor further illustration, here are shots of the closest ruler in both series. Here are the results of the focus stacks at larger magnification Here is a composite of the results of both methods showing the first and last ruler in the stacks and the results with Helicon Focus using default parameters: ![]() Using the lens to focus on the elements, the distance to each element of the stack varies. With the focusing rail, the distance from the camera to each element (ruler) in the stack is 40 cm. I arranged some rulers spaced 5 cm apart, with the first ruler about 40 cm from the focal plane of the sensor and created stacks using both methods. The results are somewhat different and I did a simple experiment with the MicroNikkor 60mm f/2.8 AFS on the D800. With an auto focus lens, one can use the focusing rail, moving the camera to successive focus points, or leave the camera stationary and focus by adjusting the lens. With the manual focus lens, one has no choice but to focus by use of a focusing rail. CAMERA NOT FOUND ON ANDROID HELICON REMOTE SOFTWAREDoes Helicon remote bring enought to the party to make it worthwhile for me to continue the struggle to get the camera, the rail, the Nexus 7, and the software all playing together? Is this game worth the candle? Finding a battery powered USB hub, having a rat's nest of cables, etc sound messy in the field. I figure that it should move the rail when I hit the focus arrows. when I try to focus with Helicon Remote, nothing happens. I have a Zeiss 100mm f/2 ZF lens on the camera. Actually, I don't have any idea what such an indication would look like - there seems to be no place in the software where the rail should be. Helicon remote recognized the camera, but gives no indication that it recognizes the rail. There's a diagram that says the same thing on the Cognisys web site.ĭoes that mean I need a USB hub? I set one up, and hooked the Nexus 7 up to the uplink side, and the camera and the rail to the downlink side. The Helicon Remote help file says to hook both the camera and the rail up to the computer running Helicon Remote. I tried hooking up just the rail, but Helicom remote doesn't recognize it. I have a OTG USB cable, so I can hook up one USB device to the Nexus 7. CAMERA NOT FOUND ON ANDROID HELICON REMOTE HOW TOMy first problem is how to hook up the rail and the camera, a D800E, to the Nexus 7. ![]() Since it was cheap to buy when I was buying Focus, I bought the Android version of Helicon Remote. I've bought the Stackshot rail, and have figured out how to use it with its own controller. I will be using Helicon Focus for image processing. I'm going to be making some focus-stacked macros. ![]()
