If I am not wrong it is only possible to abort the shots with stackshot, now I think it would be a useful feature to be able to pause/resume also. Mete, I think you're right about this behavior of the StackShot, and that it would be a useful feature for the StackShot to include a pause/resume funct...

That is about as unethical as a lawyer sharing your case details with the opposition. I was hoping that such behaviour was not real but seems like I was mistaken. I agree--totally uncool. I do sympathize with the difficulty that small software vendors have in getting paid for their work, but this p...

You have surely thought of this, but is there any chance that the corruption issue started with the current version of DSLR Remote Pro? After all, 20,000 images is just over a dozen stacks at 1600 images per. In my experience, in this case, it is not the software. You have to write real crappy code...

If you could live with a 10mm diameter COB you should look at Yuji. 9W, 5600k, 98 cri. Although it is "self-serving" check out their website for some very good info on high CRI leds. (At this page: https://www.yujiintl.com/high-cri-led-lighting.html ) I've had these COBS on my electronics bench for...

JW, looks great! Thanks for posting your implementation. I like your replacement eyecup and contact cement approach. Batteries vs. wall power is probably a "to each his own" sort of choice. I started minimizing batteries in the studio because it used to seem like every time I was ready to shoot, I h...

George, welcome to posting! :D Rylee Isitt is a member of this forum, though I don't recall seeing posts from him in some time. When he first built and documented his stacking controller, he posted on it in the thread: How to build a focus stacking controller . If you click on that thread, you will ...

Ugh—intermittent issues are the worst. A few thoughts (Disclosure: I've built a lot of Windows PC's, and troubleshooted many more): 1) Do you have the option to save images to both PC and memory card? If so, I’d be inclined to try this for a few stacks, to see if the corruption occurs on the same im...

Dik, In case you're not already aware of RAFCamera in Belorus, it should likely be pointed out. Raf seems to be a one-man shop. From experience, we know that he makes good things, and he seems to ship more quickly than most cheap items from China. RAFCamera's "M26 (Mitutoyo, Nikon BD) female to M52x...

Dik, Building on Sym P. le’s good thinking, but with different parts that should eliminate the need for custom work, how about the following arrangement from parts listed at Thorlabs Optical Component thread adapters : 1.

Perhaps either AC254-100-A-ML, AC254-125-A-ML, or AC254-150-A-ML, here: Thorlabs Ø1" Mounted Achromatic Doublets, AR Coated: 400 - 700 nm. I haven't tried any lens of this type, but have a vague memory that others may have?

you have to watch out for sellers from china, they often offer fakes. Tomek, do you have evidence of this? I've tested a lot of Mitutoyo objectives, including some from China, and never have I seen a fake. I have seen real Mitutoyo objectives that performed badly--apparently due to rough handling t...

Ranstice, I've moved your thread from the gallery to Technical Discussions, where you're more likely to get helpful feedback on your issues. I also added a couple words to the title of your post for the same reason. As a first step, I'd suggest shooting a much deeper stack than 40 images, and make s...

What I found is that even on the calibrated screens in the printing lab, it's not always the same. It could be quite different on two different types of papers.

Clarnibass, I'd suggest that when choosing a monitor, a key question is: Do you want a screen that is pleasant for you to look at, and nothing more? Or do you want a screen that will help you prepare photos for print or for other people to display on their screens? If the former, then you can probab...
