ISO 25600 or 16000 ???

One of the few disadvantages of photography in North Yorkshire is that you are often operating under steel grey skies just after dawn. In my case I am also usually under a canopy of trees. Although not ideal, this does bring the low light capabilities of the Canon R6 Mk2 come to the fore. 

This weekends experiments showed that images at 25600 were struggling with a pixelated background, but that images at ISO 16000 were perfectly usable. This will be my new maximum variable ISO limit in future. 😊
