D800 Monochrome Sensor Conversion - Comparison

[TedBaker]

i would search for monochrome cameras on the web.. e.g. below

http://www.red.com/learn/red-101/color-monochrome-camera-sensors

Still confused, I understand how they work, what I am trying to understand is what your trying to show? Are you trying to show what it looks like with out the picture being demosaiced and if so for what purpose, or something else? Sorry it is not at all obvious what your trying to show. The heading suggested it was a comparison between the D800M and the standard one.

300% crop - unfortunately i get aliasing on the checkerboard pattern but you can see how much sharper the D800 monochrome conversion is.

Without the color filter array how much faster is the camera? 1 stop? Half a stop?

i am getting 2/3 of a stop..

Also in UV Bob?

Looking forward to seeing some UV results...

yep... in UV i get more.. pretty soon i will have a D800 UV-VIS-IR for comparison but for now i have some examples below.. i can take handheld UV shots outside... am expecting a Convoy S2+ 365nm Nichia UV Waterproof LED Flashlight soon to do so more testing indoors.

Using the D800 monochrome sensor conversion (no CFA or microlenses) with an accompanying BG-38 internal filter replacement while i was out photographing snowy owls, i decided to try the D800M out with an el-nkkor and the Baader on one of my friends..

This tread clearly shows how you get better accutance with a monochrome sensor. But to me other advantages is not so obvious? Leica i said to produce a picture with better tone values and beautiful greytones in their monochrome sensor, but from the pictures I have seen the accutance seem to be the largest benefit just as with the monochrome D800. I have a fullspectrum D600 and an ordinary D800. My largest prints are typically 50 cm x 75cm (the best gallery size imo) and both cameras fullfill this giving me enough accutance even cropped in B&W conversions. A bayer sensor gives you the advantage of skipping filters. To me it seems different software can make more differences than just a monochrome sensor, so I have stuck to lightroom/photoshop for my B&W conversions because I have learned the software... But since I never have used a monochrome sensor, I might be wrong? Any comments about what to gain except for accutance trying out a monochrome D800 in my photography?

As noted above, an extra 2/3 to full stop of sensitivity. This makes low light photography without a tripod easier. Seems good for street shooting or interior work.

Bob, those UV results are rather spectacular, given the short exposure times!!

So from that, such a camera would work well as a scientific instrument to do documentations,
from an artistic standpoint, I prefer to have some false UV colors ;-)

without the CFA and microlenses you realize a significant increase in speed.. so much so i could easily do walk around UV movies (video) with the D800M

someone named Robert Suffak robert.suffak@bluewin.com contacted me at my web site after reading this post and i tried to reply to him at that email address with no luck.. all came back.

he wanted to know who did the conversion ... i responded maxmax.com
