HF 7.0.0 Mac Beta testing, part one: Alignment problem
Posted: 02.04.2018 20:10
Hi Stas,
finally, here comes part one of my testing results. Originally I planned on starting a single thread on beta testing, but when I stumbled across the problem described below I felt like it deserves an own thread.
The other day I started a DOF test stack with a microscope objective. Object was a plain piece of black cardboard in a diagonal angle to the optical axis. The (correct) rendered result from HF 6.8.0 looks like this:
However, if I render the very same stack with the very same settings in HF 7.0.0, it looks like this:
(see attachments below)
In both cases I used method C - I also tried methods A and B with basically the same scaling error. Next, I tried to modify the alignment settings which initially had been standard in both HF versions (V 3%, H3%, rotate 0°, scale 5%). I found out that if, in HF 7.0.0, I set the "scale" value to zero, the result turns out fine, just like the 6.8.0 output (keep in mind, I used an infinite microscope objective with an approximately telecentric behavior - I would not recommend using a zero value with a macro lens...). If I set the value to 1%, I already get a misscaled/misaligned result, and the higher a value I set, the stronger the misalignment gets.
Next thing I tried was using alignment settings 3%,3%,0°,5% again but additionally checking "Manual detection focus area adjustment" - just to see what happens; as yet I don't have a clear idea of what this setting does. This did not give me any additional options (as I had assumed because it's "manual"), but the rendering result looked dramatically difficult:
(see attachments below)
This result is not correct (pictures that were erroneously scaled up without "Manual detection" are now scaled down a bit, and there is some misalignment visible in details), but obviously aligning is done in a very different way.
I tried the same object with a 4x objective (examples above are 10x) with the same strange results, so I think the problem is, partially, object specific. After doing about a hundred stacks in 7.0.0, this was the first one showing such a strange effect, and the object is quite different from what I usually have (wouldn't take an object as boring as this, if not for DOF testing purposes). Nevertheless, since HF 6.8.0 did not have the least problem with the stack at default settings, there must be something working correctly in the old version that isn't in the new one.
I uploaded the stack to your FTP server (Stephan_misalignment.zip), so you can use it for testing.
Oh, and last but not least: The HF version I use is still 7.0.0 from Jan 15, 2018. Maybe meanwhile there is a newer build? If so, of course I would like to try that - quite likely the other issues I found (which are mainly GUI specific) are already resolved.
Kind regards
Stephan
