At this point, most sensors are 14-bit capable. While the sensors in Hasselblads are 14-bit, it has been said that they pad the files and advertise that they are 16-bit. This is marketing, not engineering.

 

12-bit image files can store up to 68 billion different colours and 14-bit image files store up to 4 trillion. As a point of reference, all JPEGs are limited to 8-bits and if produced with skill can look terrific. The human eye is only capable of distinguishing between 2.5 and 16.8 million different colors and that is covered by JPEGS. Nothing wrong with shooting 14-bit files, but don't expect to see an improvement unless the image is horribly underexposed.

    • You do have some options. If you want to use Apple’s Photos to take care of storing, managing the files and lightweight editing but want to also use an raw converter / editor with more “oomph”, you can do that as well: https://support.apple.com/en-us/102259 scroll down to the part about “Install Mac apps …”. Affinity Photo comes to mind: https://www.youtube.com/watch?v=R2Zt1NDfC7E https://affinity.serif.com/en-us/photo/ DarkTable, a raw convertor also has a dam built into it, you might like it. This program has a steeper learning curve than Photos does, but it is very powerful: https://www.darktable.org If you are inclined to do a little more asset management yourself, RawTherapee or Fujifilm’s Raw Converter are pretty good: https://rawtherapee.com https://fujifilm-x.com/en-us/products/software/raw-file-converter-ex-powered-by-silkypix/ p.s. Welcome to the forum.
    • If you are using a Mac have you tried Photos?  You would have to use uncompressed raw for Apple support. I wouldn't say its the best raw processor for Fuji - but it comes for free with the Mac and it works as a DAM.
    • Hello,  This past weekend I shot a weekend-long event. I took the X-H2S and the X-T30II as a back up to the X-H2S. The latter never failed me once, even with the brutal heat (though I got the overheating warning literally in the last 15 seconds of the last day of shooting). One problem I did have is that I wasn't expecting to have such a flurry of events, so in documentary/press-style I had to shoot very fast in rapid succession at times at night. My Godox (which I am starting to hate) did fail me. The recycle time was hit or miss, sometimes fast sometimes up to 5 seconds. I changed batteries twice, yet I got the overheating warning a few times and had to turn it off and on. Eventually I took out the X-T30II and used the back up flash.  I am guessing for these evening events, I'll probably need to opt for a lithium battery-operated flash in the future/different brand. Does anyone have a recommendation? I don't usually shoot with flash, or at least I haven't since my Nikon DSLR days. 
    • i don't have my x-t5 yet, but what I do with timecode challenged cameras is record 10 seconds of timecode audio on the front of the recording from a tentacle using the microphone.  Davinci Resolve can read the first bit of video file and set the clip's timecode.  Worst case, use Tentacle studio to give you the timecode to adjust the clip's timecode by hand.
    • I tried to use the "Introduce Yourself" option but it won't open. Obviously I'm new. I'm Linda. A friend sent me his Fujifilm X-E4 camera to use as a travel camera. I've just started using it and really am enjoying the feel of it and learning how to use the system.  I understand by reading some posts that folks like to use Capture One. I'm retired and on a fixed income. It's not even close to possible for me to pay those monthly fees. I'm an old Aperture junkie hoping to find a DAM that's so easy and clear to use. Is that possible?  thanks for your time
