How do you expose LOG? (and preview a LUT)

Do you just set the normal exposure, the one you would use when recording with a Film Simulation? Or do you overexpose in relation to that normal exposure? Do you use any exposure meter, grey card, or just looking at the image and the histogram?

If you overexpose, for example, 2 points (in relation to the normal exposure), do you always overexpose 2 points unless the histogram peaks, and in that case you overexpose a little less?

I am talking about 10 bits LOG. I have the Fuji XT3 which doesn’t have LUT preview and I don’t have a monitor with that option either. I am going to rent a monitor soon, so I would like to know…

How does a LUT preview work? I mean, if I expose LOG the same as I would do it with a Film Simulation, I guess the LUT preview would show me a well exposed and balanced image. But if I am overexposing the LOG video let’s say 2 points (in relation to the normal exposure), does the LUT preview show and overexposed image or is it possible to underexpose the preview?

How do you expose fLog?  Turn on your zebras to 100% and set your camera to Shutter Speed fixed, Aperture fixed and ISO to Auto.  Increase the exposure compensation until you see zebras in the area were you want to retain some detail.  Then back off the exposure compensation until the zebras are just gone--typically this is about 1 2/3 stops over exposure.

    • I've tried a number of lens hoods, but they all have the disadvantage of not being able to fit the lens cap when not in use. This one is specifically designed to take the standard lens cap and even has a soft rubber ring to ensure a snug fit. Very nicely made in anodised aluminium. https://www.ebay.co.uk/itm/252370651839?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 (not connected to seller)
    • Firmware 2.10. Newly formatted sd card. And yes, I've taken a few shots. Menu Set up - Save Data Set-Up - Select Folder - "Create New Folder" is grayed out. So I cannot create a new folder. I'd like to create folders so I can store images by date. Any thoughts on how I can fix this?
    • If I put my X-S10 on a table (or any other stable surface), focus on subject and set an exposure the will require more than 1 second of exposure (doesn't matter how many, just make sure that the desired exposure will be more than 1 second), set a timer for 2 seconds and take a shot and the IBIS is set to mode 2 (Shooting only), the shot comes out completely blurry, just like if I hand held the camera (which I didn't). I repeat the EXACT same steps but this time I set IBIS to mode 1 (Continuous) - shot is tack sharp. Why? I know that IBIS should be disabled if the camera is on a tripod or any other stable surface, my question is why this happens only in mode 2 and not in mode 1 as well?
    • Ah a flick of the 'Auto' lever has fixed it! Why do they have to make things so obscure! If it said in the manual 'ES not available in Auto mode' that would have made life so much easier! Anyway, thanks for your help @Greybeard!
