Hello forum,
Not sure if this actually a bug of A.Ph. or of defect hardware, but the consequnces are not ignorable:
When I do focus stacking (jpg, e.g. 90 frames) and latest when doing local retouch there appearing fine white horizontal stripes in a random pattern. Sometimes smaller or bigger white blocks appear in addition. Please check attached photos and video (sorry for 90° failure).
If exporting in tiff for Lightroom the defects can't be cloned/stamped away, they just do not exist for Lightroom. When converted to jpg it is possible to eleminate the defects.
This failure does not appear in Photoshop, Lightroom and (new purchase) in Helicon Focus.
My tackle list:
New installation of the latest version of A.Ph. => no improvement
Power supply step-up, 400W to 750W => no improvement
Installation of (small) G.C. (Quadro P600) to exclude the internal GPU => no improvement
Plan: exchange of RAM module => not yet tested...
My system:
MPG Z690 EDGE WIFI DDR4
Core i5-12600K LGA1700
16GB Cructial DDR4-3200 DIMM CL22 Single
no graphic card (no need for me and it didn't eleminated the problem)
Windows 10 Pro; version 21H2
So far I couldn't find anyone mentioning this failure.
The retailer asked to send in the board and components (he mounted these parts) for a check. But I'm afraid the problem is so specific that it's a waste of time finally...
Is there anyone who can report about this failure as well and even about a solution?
Could any one advise me what to check and how to proceed?
Thank you very much in advance!
Chris
