Placed 14^th in the challenge. The image is processed to emphasize the color hues of the moon - our satellite is not gray !

Seems like you know little about Pentax...

On top of the new model, from the current catalog you can choose from:

FA 50 f/1.4 220g, 270$
DFA 50 f/2.8 macro 260g 346$
DA 50 f/1.8 120g 110$

Placed 40^th in the challenge. Wonderful wild shore in the south-west part of Corsica Island.

Placed 21^st in the challenge. Not Mt Everest but feeling like being at the top of the world ! Perfect weather and incredible views towards the Yungas and the Amazons basin.

Placed 50^th in the challenge.

Rishi, maybe you could try this:

From Rawpedia (Rawtherapee online help):
"When working with very noisy, high ISO images in conjunction with the Noise Reduction tool, it is recommended to use the...

So the strong grid pattern on the 2-frame stacked image was related  to the processing/stacking workflow. Thanks to Ian and Rishi for sorting that out. The Lonely Speck rating is back to 4.5 ...

This is a nice, well-composed capture and the workshop was certainly fun ! If I may have a suggestion: I have tried with a warmer white balance (lot of blue in your sky) and reduced  saturation, ...

This is a likely possibility, it would be useful to have access to the RAW files used in the Lonely Speck's review. Just to complement my previous post, here's a comparison between the 2-frame ...

This is strange. Usually fixed-pattern artefacts are removed by stacking rather than exacerbated, thanks to dithering ( i.e. slight change of framing) between the shots . Edit : looking more ...

I really like the fourth one a lot !

This matters only for point sources (i.e. stars). For extended objects (Milky way, Andromeda galaxy, Orion nebula,....), which are characterized by their surface brightness, only the f-number ...

BlueBomberTurbo, I was referring to details rendition not to noise levels so my point is valid

Nomoreheroes it depends in which part of the world you are living. In Europe the D850 is 3799€ while...

Thanks to the DPR staff for the effort put in the new shooting.

I have compared as objectively as possible the output of the K-1 II to its peers at 6400 ISO, concentrating on the text zone - a...

Dear Rishi,

one more request for clarification on this point. I am among the many that noticed an image change on your comparison tool at 12,800 ISO (the one that you used to back your assessment...

I confirm these findings. The day the review came out I developed myself the RAW files at !2,800 and found that the K-1 and K-1 II were almost on par in term of details, in particular K-1 II ...

Given that apparently there is noise reduction in the  raw files above 640 ISO, could you compare something like 400 ISO pushed 2 stops and 1600 ISO ? I need to know whether the NR in raw is a ...

Difference in contrast is probably gone by matching carefully the histograms (dark areas are darker on the Mark I picture). About sharpness I agree with you that the Mark I looks better but (i) ...

Continuation of my previous post. Here is the result of my conversion with RT at 12,800 ISO (Mk II left Mk I right) - MK ii files have to be pushed +0.7 ev to match exposure of Mk I (confirmed at ...

To be sure I also checked with Darktable, exact same results : Mark II image darker by about 0.7 to 0.8 stops. Strange isn't it ?

Could the problem be in your raw conversion ?
