  • Did you watch the video that you linked to? Skip to 6 minutes in and he discusses why it doesn’t work on photographs! And yes I have used it, for rendering/visualisation it’s pretty incredible. Top ...
  • “A bilateral filter is a non-linear, edge-preserving, and noise-reducing smoothing filter for images,” I hate using Wikipedia as a source but... I’m happy with that definition so why not hey ;-) It ...
  • Superpixel demosaicing, giving you per-pixel Chroma and Luminance — what do you think Ted?
  • This entire discussion is moot because the OP has used ETTR to photograph a flower, underexposed 90% of the scene, and then lifted the shadows to show his dissatisfaction with the Merrill's SNR. Fo ...
  • Can we please just pause on this?! If you analyse the binaries and instruction sets in SPP you will find no mention of NLM, so it's baseless to keep repeating this. Median and Bilateral are the 2 ...
  • Not to be a bore but... desaturated shadows and speckling in OOF areas from noise reduction, which are Merrill traits for SPP. And for an image that isn't razor sharp, there are lots of rendering ...
  • Replied in Fine :-(
    Interesting choice of the word "fine" − speaks to mediocrity :-D And yet the colour and tint differences are very obvious to the eye (18% Grey especially, which isn't very useful), and a colour ...
  • Thanks Shawn, that's that settled then! For the OP, it's important to set the correct WB in camera because SIGMA uses a 3x3 colour matrix for WB − whilst the DNGs include a Dual Illuminant profile, ...
  • No because Quattro OOC DNGs are 100% scene referred (thus can legitimately be considered RAW); the DCP/metadata contains the colour matrices for White Balance and colour mode, a cLUT and the tone ...
  • Even at ISO 100, yes Merrill will be noisy if underexposed − the problem is balancing the exposure; knowing the issue you'll want to expose for the shadows but then you're likely to clip the ...
  • Replied in Thoughts..
    But that's not what it's designed to do, you're describing highlight-weighted evaluative metering which the DP3M does not have. I've only owned 3 SIGMA cameras (dp0 was the newest) and I've come to ...
  • SFD and the fp's continuous read-out ISO mode are positive signs for SIGMA, in my book anyway. Olympus are my top choice for innovation, both in hardware and shooting modes, they offer an ...

    But why not take multiple readings vs pointing it at a highlight/shadow and "calculate(ing) in your head," just use the meter, no... ? :-| But if my scene has a subject e.g. I've just come back ...
  • Colour matrices i.e. conversion matrix, white balance and colour mode are all contained in the X3F metadata. SIGMA does update these with firmware updates, and the result may not be a wholesale ...

    Well... that's a weird way of using Spot, surely? I never take one reading, I take a highlight/mids/shadows reading and then guesstimate the exposure that I want/need. It's looking at changing ...
  • Replied in Thoughts..
    That's interesting, I only use spot metering with my SD1M... in what way have you found it to be "wrong"?
  • What? For fear that this has all just been for a giggle, I'm going to bow out now because this is nonsensical.
  • Sorry... but I'm really curious as to what device you're working on, 13"? That's a lot of GUI for a tiny preview! No condescension meant/intended.
  • But I still don't understand the point of your post... ? The exposure looks 'correct' (enough), the problem is that some of your highlights are blown, yes? ISO isn't going to change that and SPP ...
  • +2, it's ISO 100 or bust here :-P
