How to get sharper images in very poor light?


Recommended Posts

Hi, @Kim Howells thanks for letting me join. I am not sure what to do, so hoping for some guidance. I took this image on a Sony A7ii with a 70-300 lens @194mm f6.3 1/320 iso 1000 (this was the lowest I could take it). It was very gloomy/dark & raining. I shoot raw & handheld today. This site would only let me upload a jpeg. I positioned myself under the clearer sky, which let in a little more light and removed my lens hood. that gave me an extra stop of light. I am just baffled as to why these images are not sharper, is it just down to rain and the high iso? I just do not know what to do to make the images sharper. I usually use a monopod but the ground was flooded and very soft.
Thanks

Hi! I think there could be a few factors here. ISO and rain like you said, but also underexposure (exacerbating the noise), movement blur (not the lack of a monopod, but from the kids). Can you please post a 100% crop of his face? Edited or unedited is fine.

That's correct, your first post wasn't as it's not square. The 700x700 is a good way for us to check that it's correctly cropped so it can be assessed at the right resolution.

Noise and underexposure are the major issues here. It looks to me too that there has been movement away from the focal plane, ie he's moved backwards or forwards from the point at which you focused. You may find there are other areas of the image that are more in focus as a result. 

You'll need to be careful with noise reduction for this to be usable, but it'll never be sharp.
