  • You do know you can add individuals to an 'ignore' list. If you feel compelled to reply to every poster perhaps you too are some combination of 'Highly opinionated, very obnoxious and obstinate'.
  • In the film days when you were basically limited to ISO 400 slow mattered. In today's digital world where ISO 1600 isn't even pushing the limits of the camera not so much.
  • Convert them to Digital Negatives (DNG) using Adobe DNG converter . Or do the initial RAW conversion with Canon DPP to a 16 bit TIFF. Then edit the DNGs or TIFFs in LR4.
  • If you are exposing for the non-specular highlights then you aren't underexposing.

    But, if after setting your shutter speed and aperture as your scene dictates you can increase your ISO without...

  • Just be sure you aren't confusing out of focus blur (bokeh) with noise.
  • Your first reply about ISO in this post, no mention of blown highlights. And no evidence that you understood that underexposing reduces the usable DR the same (or more) than increasing ISO and...

  • Stop pixel peeping. Spend $3 and get an 8X10 print done at Walmart. Then decide if the noise was an issue.
  • What I took issue with was his statement that increasing the ISO to properly expose (ETTR) was some how worse than underexposing and pushing the photo in post processing.

    For ISO-invariant...

  • So while with an ISO-invariant camera there is not a penalty to the DR of the exposure compared to raising the ISO and properly exposing the photo (ETTR), this doesn't mean it is 'better' than...

  • And I am saying it is true for any camera with a measured amount of DR. i.e. all current cameras You seem to be confusing ISO-invariant with infinite DR. They are not the same.
    The DR measurement...

  • You still have 14 stops of DR. But, if you underexpose by 3 stops you are only using 11 of those 14 stops. The top 3 stops of DR are not utilized and are lost. Again, DR not used at the highlight...

  • Rishi Sanyal: You are aware that DR shrinks with ISO setting, yes?

    Yes, I'm aware of that, and for cameras with Sony sensors it is pretty much a linear drop. For Canon cameras not so much.

    But,...

  • If you don't expose to the right, you are throwing away stops too. Using a lower ISO and underexposing a photo doesn't gain you any DR. If you have 12 stops of DR and you underexpose by 3 stops you...

  • If the 5Ds has the the same per pixel DR (11.43 DXO screen) of the 6D, based on the formula linked above it should have a DxOMark Print DR score of 12.75 EV.

    DR Print = 11.43 + log 2 [sqrt (50/8)]...

  • Thanks.
    The 8mp is fine.
    From DxO: 'However, any other resolution can be chosen, as doing so only shifts the normalized values by a...

  • I try to compare like generations of cameras, i.e. 6D vs D600/D610, 70D vs D7100, and now the 5Ds vs D810. Since each generation from both manufacturers shows improvements.

    As has been pointed out...
