Pushing Pictures

Tonight I got my new lenses and decided to play around some more with flash as I was taking test pictures. I am a complete novice when it comes to flash and now I'm trying to get used to RF triggers. I had the flash set too low, and got this very underexposed shot:



I was going to delete it but thought I would use it to see how much one can recover in the shadows with the K-S1. So I used Lightroom to adjust exposure and shadows, and came up with this (and yes, I know the background is pretty horrendous):



I was amazed that it looked quite reasonable. I was shooting at ISO 100 and the extreme lightening did introduce noise, but not as much as I had expected:

Here's a 100% crop, to show how much noise there was:



It cleaned up very nicely with a little bit of Topaz Labs DeNoise.



I'm really glad I tried this. It gave me confidence in the camera's ability to stretch the shadows more than I had expected. I'm not sure I could have gotten this type of result with the K3, though I routinely did things like this with the K5 (and had less noise). The photo was taken with one of the new lenses, the DA15.

I played a little with K-S1 and it is not that horrible like some people say about that camera. Regarding the capability of Pentax camera to recover information from RAW files I have to say that I'm pretty impressed. Your picture is a good example.

Looks great. Things we can do with images these days are amazing. I noticed that already in 2012 with K-01 files.

Neat! So you have at least two of the DA Ltds now - is the K-S1 still demanding more? (It'll do that!)

I now have 3 silver DA Limiteds, plus a black DA35 macro, giving my unicorn white camera lots of options.



That is all I feel a need for now - my lightweight kit will consist of these 4 lenses plus the FA 31 (the lens I used to take the above picture) and the FA77. I can't quite see getting the DA70 just because my 77 is black.

Tomorrow the 100WR will be arriving, so I'll also have a relatively light-weight 100 macro lens, which will make my kit pretty complete. I'm staying away from longer lenses right now.

I've had mixed results recovering details from shadows. The K5 was the best in my experience with the K7 being the worst (lighten a little and the noise was completely out of hand). The K3 is so-so. I shouldn't judge by just this one picture, but I think I would have gotten more noise with the K3 than I did in this shot. It wouldn't surprise me that the K-01 would be excellent with it's 16 mp sensor.

K-7 was much less in quality then the later sensors. Didn't try that with the K-3, but I would expect it to have less room for editing the the 16mp sensor.
