Sinar e75lv problems
« on: March 03, 2008, 08:25:39 am »

Mostly I got perfect images from my e75 Sinar Back.

The problem sometimes shows up in highlight/overexposured areas. Strange squares.
A light centerfold effect in the blue sky in one image.

I use the standard CCD-file deliverd with the back and Brumbaer Tools / Lightroom.

100% magnification:

Thank you Rainer.

I will test this more carefully later in the week and compare with CaptureShop

Maybe Brumbaer Tools are trying to recover to much and reach some kind of limit. I know, these are strong overeexposed.

No problem.

Stephan sent me another version of the program.
It recover not so much as the original version and works better on some images.

which version number you received ?
1.45ß6 ? take care with this version it is about one stop more sensitive and blows out this data. i work with 1.45ß1 and prefer to make a lower exposed file as well, where do not happen similar artefacts.

My original one is: 1.44, now I got: 1.45ß6.
I have compared the results and something between would be better.
Can you please mail me your verion rainer.
