I did an event this past fall in a gym

manual, auto iso, center weight average, f1.4, ss 1/250, 7 fps squish technique, and took shots of pairs -- just dropped back to 8 feet to get the 12 inches of dof -- all four eyes in focus - dxo PL5 NR --

know your distance and dof -- fantastic setting!!!

Thank you for this tip. You packed more good info that than is in the rest of this whole thread !

u r welcome

I have an app for my iphone 13 called

Simple DOF

study the app for your f1.4 setting on crop cameras, know your dof with the f1.4 setting and distance, plan and visualize the shots before ever arriving on the scene.

some of the best shots I've ever taken in over 1 million shots in 20 years, took study and planning before I ever arrived on the scene - it was as if I anticipated the shots, before they ever presented themselves, and I was in the right place at the right time ready with the right settings.

Set up on C2 on my out and about M6II.

What is your auto iso max ?

RAW with 12,800 max- and dxo PL

If you're shooting RAW (not CRAW) and using DxO PL, ISO 12,800 will give you no more shadow detail than shooting at ISO 3200 and pushing exposure using DxO. All you do by shooting at ISO 12,800 is blow out up to 1.5-2 stops of highlight detail, losing dynamic range. See the post at

interesting Larry - so you are saying it is iso invariant at iso 3200 and up?

Yes - all explained in great detail in the thread I referenced. See this post:

also - what does this underexposure do to exposure simulation - can I even see what I'm shooting?

To shoot in low light using the 'underexposure' technique you would turn Exposure Simulation off in the menus. The light meter indicator will let you figure out where you are shooting: -1 EV is ISO 6400, -2 is ISO 12,800, -3 is ISO 25,600 which is about as far I usually go, although I've experimented with higher a few times.

Thanks Larry

In the recent event I shot extensively between iso 3200 and 12,800.  I used auto iso.  Mostly use Center weighted average metering.  The exposures were fabulous.  When i look on my screens, I want to see great exposures.  Great exposures are a high priority for me, particularly when I'm taking many 100's of images, it is more important to me than even razor sharp results.  In fact, I do little sharpening at high iso's, and rely on razor sharp lenses. Doing a lot of sharpening of images at high iso is not something I advocate. On the thumbnails on my camera screen and then computer screen i want to see beautiful exposures.  If I don't -- I know something is wrong immediately -- blown exposures -- and needs changed on the fly when I first start shooting.  When I shot the theatrical events i was hired to do, I knew something was wrong almost immediately and switched to spot metering -- those type of settings with spot lights are rough -- and I suspect your trains at night are similar rough exposure challenges with those train lights coming at you.

Your mention of blowing highlights, it looked to me like you were dealing with a different type of setting than I was with darkness and the train lights where the lights were causing difficulty on the high histogram side.  It's like dealing in a theater with spot lights where I had to change my metering to spot metering.

My setting was in a gym with low light elementary school lighting, and not spot lights of trains coming at me.

That said, I don't like to underexpose and see poor exposures in all my thumbnails on my screens - were talking 1500 for my last event.- underexposing all those shots would drive me crazy

I do agree that deep prime needs adjusted.  I don't allow dxo to make its own standard adjustments, but maKe adjustments to each like/similar image set and recipe the settings onto other similar images.

In my case, for my last event, the noise control of dxo PL was amazing.  It produced better results than my FF cameras on their own can produce -- which is saying a lot for this software AI magic.

I will give your method some consideration though the next time they call me to photograph in the theater -- where the spot lights drive me crazy -- and if you do not use spot meter and underexpose the scene  -- you'll blow the exposures -- and your results will not be pretty.

Thanks for your input.
