Originally posted by Mash4077 Continued thanks for all the help and feedback, as mentioned earlier I have picked out five images that I believe to be failures for one reason or several.
These are all still in DNG format and are straight out of the camera so file size accordingly.
01 - Pentax-DA 35mm f2.4 @ ISO 3200, 1/60 sec
02 - Pentax-DA 50mm f1.8 @ ISO 3200, 1/80 sec
03 - Pentax-DA 35mm f2.4 @ ISO 3200, 1/80 sec
04 - Pentax-DA 50mm f1.8 @ ISO 3200, 1/100 sec
05 - Pentax-DA 35mm f2.4 @ ISO 400, 1/20 sec (Tripod)
The first four I believe have considerable noise in them.
Any and all feedback gratefully received, I am happy and expecting criticism but if you can give pointers that would be great as these are the type of shoots I enjoy and have another bus one lined up for September which I will be using a tripod for next time.
First you never mentioned owning these in the original post so some of the advice given may not be applicable. These lenses are fast and while not zooms they exceed the f/2.8 zoom aperture speeds we were recommending.
Next (again I have not yet looked) what is the post processing you are doing? These are the straight DNG files which gives us the option to tinker but tells us very little about how you process them.
My initial observation is that you shot with pretty high shutter speeds for night shots. 1/80 @ f/2.5 on the 2nd picture, 1/60th @ f/2.4 on the first I think. Why so high - was there movement in the scene you needed to freeze in all cases? I suspect in the first one there were moving cars but you probably didn't want them in the scene in any case as they are anachronistic.
Lighting is hash and you have a number of harsh lights in the compositions that make the camera work pretty hard to try to hold the scene. Your white balance appears off to me - was this shot auto? In post you can easily correct.
Looking at the shots you liked one thing is clear the composition of those shots is better than the shots you took at least in some cases. There are no modern cars captured and the street lamps in frame are more period etc. Oddly you put forth both cool modern looking images and nostalgic old film looks - I'm not sure which you wanted from your results. Lastly I noticed that these are all reduced resolution flickr shots. The pixel peeping noise you see may disappear if you create reduced resolution jpgs and apply good noise reduction.
Saying all that is easy... now for some real fun. Here are a couple of your shots remastered - I'm not a great Post Processor - others can do better I suspect but at least this should give you some idea how manipulated things can get.
Oh and shake reduction should be OFF when using a tripod. You can do this by setting the setting specifically or by enabling the 2 second self timer.
