Hi,  i’ve had a look around the internet and can’t seem to find anyone with this issue.  Long story short is I used to be able to access my CF Express type B cards that are formatted by my XH2s on my pc and my mac.  They would pop up as an external drive through an external Sabrient reader.  Now they don’t?!  Has something changed in the firmware? something broken. A few observations: It now happens with all of my Sabrient cards. I bought a new Lexar reader and it does it with that too. If i format the cards on my RED camera and then mount on the computer they work fine as expected.  Once I put back in camera and format the card then place back to PC it doesn’t work. The only way i’ve been able to access the card is while it is plugged into the camera but this seems a lot slower to transfer data. Has anyone else noticed this? would appreciate any solutions. 

Replied with samples on a different forum

I know this is an old thread but I just ran into the same issue with my x100t. Wondering if you ever found a solve. 

Thanks!

Which direction is the light source coming from in the dark images? For example, if it coming from behind the subject, a common occurrence known as backlighting, put some light from the front toward the subject — you can do this with a flash unit, or by using various types of colored reflectors. Or, use long exposures with various grades and types of graduated neutral density filters to bring out the dark areas without blowing out the highlights. Or try bracketing exposures. There is a technique called ETTR, expose to the right, which will bring out shadow detail but risks blowing out the brighter sections. This may help in understanding DR settings as well as Dynamic Range Priority: https://www.jmpeltier.com/fujifilm-dynamic-range-settings/ p.s. The situation you are describing has been one photographers have struggled against since cameras and photographers have been around.
