10 Years after ..

Discussion in 'Nikon' started by Albin''s images, Jul 11, 2022.

  1. I suspect it's not just the dynamic range. The filters used in the Bayer array will also greatly affect the colour rendering.

    Some years ago I pointed my collection of digital cameras into a simple slit spectrometer aimed at the Sun. Had the cameras been capable of capturing pure spectral colours, their output would have looked continuous like the top, simulated spectrum. However.....

    The discontinuous patches of red, green and blue with little overlap are what resulted. The near 'brick wall' filters used are great for colour saturation, not so great for colour accuracy.

    Note that spectral yellow, cyan and violet frequencies are greatly attenuated or completely missing. And that don't seem like a good thing to me.

    The differences in rendering can be seen first hand by selecting different cameras in Imaging Resource.com's 'Camera Comparometer'.
    I recommend the still-life selection of samples, where the different rendering of fabric colours and wax crayons between cameras is quite instructive.

  2. Thanks both for your responses. I'll play a bit with the DxO graphs and I have played extensively with the film emulators. I'm captive at home this week so may do another deep dive.
     
  3. Kinda makes you wonder how they got them there colours with R G B filters on a monochrome film camera now don't it?
     
  4. I see what you mean. The Df crayons are a lot smoother and more satisfying. Also, there is a roughness in the D850 sample where the crayons meet the gray background, like a bad halo effect. Also notice the dark and gray backgrounds.... the line where they meet is a lot smoother on the Df than the D850.
     
  5. Hummm, Df 8.7MB v D850 27.9MB Df 16MP v D850 46MP.

    I suspect it's down to the AA filter and fewer pixels that make the Df shots that way.

    If I've got a mo', I'll see how downsizing and a bit of mild Gaussian blurring a D850 shot looks.
     
  6. The old gel or glass dyed-in-the-mass tricolour filters were a lot broader in their response than current technology allows. The sharp-cut modern Bayer filters only work because most real-world pigments and dyes don't reflect near-monochromaticly, but over a broad Cyan, Yellow or Violet bandwith.
     
  7. Can't we have a C M Y luminosity filter pack...? :p
     
  8. Kodak tried a CMY filter-array sensor back when they were still modifying Nikon film cameras to digital. The results were.... um... interesting.

    Personally, I don't know why the excessive green filters aren't replaced with Cyan and Yellow. With some clever maths you can then create 2xG, 2xR and 2xB from one 4 filter sampling, thus doubling the sensor sensitivity. But then, what do I know?
     
  9. I'm a Canon, not a Nikon user and I don't have anywhere near the depth of knowledge or experience of previous posters. I just read on Wikipedia that when released, the D800 was a 36.3-megapixel professional-grade FF camera that got the highest Dxomark rating for image quality and received a Gold Award by Digital Photography Review. So if it still meets your current needs, I would have no hesitation in picking up the 2nd one at such a reduced price!

    FWIW I still use a (2nd hand) Canon 6D which was released in the same year as the D800 at 80% of the D800 price but probably with much-reduced capabilities relative to the D800 (image size and quality).

    As always, I still believe that the photographer (and not the equipment) makes great (or not so great) photos. The equipment just has to be 'good enough for the photographer to express himself/herself.

    PS. After reading up on the D800, the thought occurred to me that a new category 'classic digital cameras' might be added to PN :).
     
  10. ;) 'Classical Digital Cameras'

    And after 1,5 weeks jumping around with one (mm mmm.. only one) of the D800s in Montenegro, I can only again conclude that it still makes me happy with its outputs and handling. Only the AF could sometimes cause irritation.
     
  11. Speaking of 10yrs, next month officially is the 10th year anniv of the D600. I don't upgrade cameras often, my previous one was a D70 so a huge upgrade.

    I am pretty much done with cameras now of any brand. Been in this game since 2004 which was when I got a dSLR the D70 and then after I got into film SLRs with my curiosity how did people shoot those amazing billboards and postcards like sunset and daytime scenes and fashion with it when my local semi pro lab didn't give me those images with color neg film even after trying an entry level film SLR and with Kodak Portra. Which was why I went to a pro lab which was $$ and then I got into slide film. I think that if I ever need a 2nd Nikon I might get a second hand Nikon Z, the thought of a D4 or something doesn't sound wise. At the end of the day my images are just seen on my own screen, share don social media with small sizes or printed to a modest size.

    I am a lot more deliberate now. I don't go and buy all the focal lengths from 16mm to 200mm and then think if I could expand that list to 400 or 500mm and some lenses both in primes and zooms. Nor do I take my camera(s) out with me on many days unless I have a specific task or shot(s) in mind.
     
  12. Which Sensor is the last one?
     
  13. Gee, you've got me there Mike. I'd need to look through a collection of not-well-catalogued shots stored under different camera model directories.

    The obvious pixelation and jpeg artefacts lead me to think it's an older and simpler camera - of which I've accumulated a small collection. They just look at me with their doleful and neglected lenses from car boot and camera fair tables and, and... well I just have to give them a good home and take them out for walkies occasionally.

  14. You can get C-41 processing at Walmart. It takes about 3-4 days.
     
  15. At least here I think that 3-4 days is the time it takes to send it out... In any case, it's not doing the processing while you stand around talking old cameras,:oops:
