Using Pixel shift with light trails actually works..

From blue hour to night time, all using 30 sec exposure

---------- Post added 12-16-16 at 05:33 AM ----------

sorry.. not all 30 secs PS.. lol.. 1st is 15 secs PS. 2nd is bulb mode at 90 sec. 3rd is 30 sec PS.

These were taken at a local park. The night shots were about 10:00pm.

Patoka Lake Sunrise.

Patoka Lake.

Both are pixel shifted with the DFA 15-30.

Great pics Rondec! I like the sunrise shot in particular.

Thank you. I think one of the things I like about pixel shift is the added dynamic range it gives an image. The K-1 already has great dynamic range at iso 100 and add in pixel shift and it is pretty amazing.

Patoka Lake Dawn.

Before Dawn.

Both pixel shift with DFA 15-30.

Totally agree. Allows me to underexpose so I don't blow any highlights and still pull incredible amount of detail from the shadows with little noise. In practice, it means I can often get away without using graduated ND filters for sunrise/sunset.

I have a question, how does pixel shift help with increaing dynamic range? It isnt like HDR where you combine multiple images at different exposures.
Not saying it isnt true, just wondering.

I think you meant pixel shift...

What I see is that it reduces the amount of noise that you have throughout the image. Iso 100 is already really low noise, but if you are bumping the shadows three to four stops, you still see some noise cropping up.

You wouldn't need a pixel shift to do this. You could take four images with any camera and use software to average them and it would do the same function. The way Pentax does pixel shift, you don't actually see much extra detail, but you do see improved color depth and dynamic range, which is more valuable to me anyway.

Aww i see thanks

That was an unfortunate typo lol

I think I am only scratching the surface of the K1 up till now.
So I've decided to dedicate some time to shooting more in Pixel Shift mode and see what I can get out of it (and what software might do it better)

As such,I leave a full sized sample on my Flick for the images I will post on this thread in the future.

K1+Samyang 14/2.8

Shot a f11.
2 frames with pixel shift and composition adjustment to get more of the bottom and stitched in PS.

Detail in the text that I can read off all the signage in the construction site is really amazing.

Process in PDCU.
One big problem is its lack of lens correction support for lenses like the Samyang 14/2.8.
I don't even know what I am doing with the Lens Correction sliders since they change so slowly and its not well described.

Thanks for posting this. It is a fine example of the dynamic range and detail PixelShift can capture. The processing challenges will hopefully be solved soon. It is a really fun picture to explore. Maybe it will inspire more of us to take the time to experiment.

There are patches of waves here and there. It does look strange to me, but then maybe that is just me.
Nice picture otherwise.

I don't think anything much will happen on the processing front as Pentax does not have the market share to drive developers to do anything for it.

As such, I am contemplating SilkyPix Developer Pro.
Reasons why I have not done so to date :
1. For the past year, I have been uncertain how much Pixel Shift I would do. (So my venturing into doing more pixel shift for 2017 will be part of that exploration process)
2. I already have LR and its very good for what I need in terms of lens corrections, exposure correction and brush corrections, SilkyPix only offers a gradient tool and radial tool for localized adjustments.
3. Learning a new RAW processor
4. Cost of SilkyPix (waiting for the special offer for those who have an older version of the software; which happens often enough)

I am dismayed that many (esp review sites and usually those newer to Pentax who picked up a K1) have largely given up Pixel Shift as an option.
Usual sited reasons being movement artifacts

May I add point 5. Try out Rawtherapee as soon as their pixel shift support is finalized.
It’s free and it seems to me as the PS support will be head and shoulders above everything else.
