Hello, As for luminance optimization, so long as you don't hit optimize in the photometric panel you should be ok. At least as far as I understand everything.
The parameters you should be optimizing are y,p,r, and v for each image with the exception of the anchor. Do not start optimizing the a,b,c or the shift params: d and e. What is your maximum error after the optimization process? It should be very low if you want acceptable results. I have used align_image_stack and enfuse to do a focus stack on a brown striped scorpion a while back. In my case, the results were quite good. If you would like, you can send the images along with the pto file off list and I can compare results I get with you. Best Regards, - Gerry If you would like you can try e-mailing your images off list and I try to.
