Hi guys, forgive my ignorance if any but I have shot JPeg in the past and within a year or so I have started shooting majority Raw and converting with AfterShot Pro.
I wanted to play around with Lightroom 5 so I downloaded the free trial. After processing some long shutter night shots (I can post later for reference) I found that the photos were quite noisy, especially in the night/sky areas. Downtown Manhattan Skyline from Jersey City on a cloudy night.
I shot at f/11, ISO 100 with shutters varying from 10sec - 25sec. 5D MkIII w/ 24-70mm v1.
I have a few thoughts on the noise:
I know noise appears in shadowy areas? But at ISO 100?
How much of an impact does the longer shutter play in noise?
I know jpegs are noise reduced in-camera, but the RAW conversion in AfterShot Pro seemed to be fine. Are the Lightroom default noise reduction settings mild?
I did overexpose a bit in Lightroom (I liked the colors) by about 3 stops, which from what I know, does increase noise? But I do not know how much.
I will have to go home and play around more with the noise reduction settings, such as detail.
Any and all advice/criticism is welcomed...
