I was just looking at some photos that I took recently and found some of the picture very noisy. When I looked at the metadata, the settings were a bit strange.
I was using a t5i with the Canon 55-250 IS STM lens. The camera was set to Apeture priority @ f11 and Auto ISO. An example of the settings, on the noisy photos, was 1/400 with ISO 6400!! This seems odd. I can see why it might pick that ISO at 1/400 but why choose that speed? The others had similar settings.
On other photos, all seemed more correct e.g. 1/100 @ ISO 320 & 1/160 @400.
To me, the issue is that the camera is selecting too high a shutter speed, at certain times. I do not know if Auti ISO has anything to do with it.
Any thoughts would be, greatly, appreciated.
