'from shadows to highlights' shadows and highlights are not the edges of traditional histogram its in the middle edges represented by blacks (left most wall value 1) & whites (right most wall value 255). What is '16383 levels', levels of what what exactly could you refer to somewhere where it explains in layman terms, i am consumer and dont need to dive deeply in the inner working of how data stored in RAW file. I also dont understand a about your histogram perhaps there is some background information needed before one can understand it. If something in the above is unclear, please say so and we will try to explain better. If the step is 0.1 EV, to fill a stop one needs at least 10 levels with only 7 levels you will see gaps, and histogram starts to look as a comb. This progression simply means that the exposure in each next stop is half of what it is in the previous, brighter, stop. , and finally, the last three stops contain 7, 3, 1 level respectively. The first stop in highlights contains half of those, up to 8191 next stop contains half of what is in the first stop, 4095 following stops contain respectively 2047, 1023, 511. In raw, say it is 14-bit raw, there are maximum 16383 levels from shadows to highlights. > The histogram step on the horizontal axis is 0.1EV, so there will always be a “comb” in the shadows, as there are less possible levels than 10 levels per stop. The leftmost mark is the left wall it is where the value in raw is equal to 1. > The leftmost mark of the scale is the level that corresponds to the value of “1” in the RAW data. Let's try to approach things step by step.

I like what your software is about, I like it's really useful features, but I'm REALLY struggling to get past the first post.Īny and all feedback greatly appreciated, Smithy. I do get that the Lr histogram is based on a jpg view, or something like that, and FRV is the accurate, real raw histogram, but that doesn't help me to understand it.

On the other hand, if your software is indended for regular enthusiasts and pros alike, could I please get some guidance on how to read YOUR histogram, what am I looking for, maybe help in understanding why are the corresponding areas in histograms from FRV and other software are so different. Maybe it is and I'm in the wrong place :-) I just feel like your software (and the user manual) is written for scientists. This feature allows me to tailor FRV to the dynamic range of my sensor, I like it! What is the value of '1'? By 'the leftmost mark' do you mean the -10 line?īy the 'underexposure level indicator' do you mean the -5 line?

The only section in the User Manual that I can find that really talks about the histogram is the section, 'Working with Exposure'. Therefore, because your software displays a histogram that doesn't look anything like what to me is a familiar histogram, I, the user, am dependent on your explanation to understand what its about. The histogram is where I get a sense for the image, but with FRV I just don't get it (it doesn't look like any other histogram I've ever seen). When I look at FRV histogram, I get in a panic, it confuses me, I can't work with it because it doesn't make sense to me. It's easy and familiar without needing to read a manual.

When I look at my Lightroom histogram, I understand it and know what I'm looking at and looking for. I also love your additional features, really useful stuff. raf files and cull, without needing to spend all that time that Lightroom demands in its import process (which in turn allows me to shoot more freely because the culling process is much quicker & easier). I'm drawn to FRV because it allows me to sift through my. Is FRV mainly created for trained professionals, or scientists? I'm an enthusiast photographer, maybe your software is too complex for me, your RawDigger is certainly way over my head. I should start off by saying, I really want FRV to work for me, but I'm not getting on with it:
