Advertisement Posted July 26, 2015 Posted July 26, 2015 Hi viramati, Take a look here What we see not what we get?. I'm sure you'll find what you were looking for!
digitalfx Posted July 26, 2015 Share #22 Posted July 26, 2015 I'm really surprised by this. In most EVFs that I've seen, when you half-depress the shutter button, you see the exposure as it is affected by the settings, as you do on the M with LV or the EVF. Change the aperture for example, and you see the effect. Have they really gone backwards with the Q? This works on the Q, but at that moment the Histogram disappears. The Histogram is eye candy only as I have no idea why its even there. Which exposure is it displaying? It surely isn't showing you what you have the camera set to even in full manual.

digitalfx Posted July 26, 2015 Share #23 Posted July 26, 2015 That is very weird. The histogram for an overexposed image should be bunched up all to the right. It suggests that the histogram you are seeing is not related to the image you are recording. I fail to see the function of a histogram that does not show the exposure of the image. Yes of course and thats exactly what I have been saying. The histogram is displaying some mythical exposure, not the actual exposure as set by the camera.

First we got snapshot mode on the M, now this. Leica does occasionally seem to have a sense of humor when it comes to its motto, 'we focus on the essentials'.

digitalfx Posted July 26, 2015 Share #26 Posted July 26, 2015 How did anyone take a decent photograph before the invention of the histogram?[emoji2] Of course, but why would you include a feature that doesn't work? In digital photography the histogram is an important tool. Link to post Share on other sites More sharing options...

hawk.kat Posted July 26, 2015 Author Share #28 Posted July 26, 2015 Arguably the recorded histogram is redundant.... So neither histogram is helpful [emoji17] Link to post Share on other sites More sharing options...
Jeff S Posted July 26, 2015 Share #29 Posted July 26, 2015 How did anyone take a decent photograph before the invention of the histogram?[emoji2] There were lots of decent photographs before the invention of film, too. And even 'selfies', better known as self portraits. Only the tools have evolved. Jeff Link to post Share on other sites More sharing options...
hawk.kat Posted July 26, 2015 Author Share #30 Posted July 26, 2015 I'm really intrigued by the histogram. It changes as one points the lens to different lightings but it's unaffected by the camera settings. For the reading to be useful, we need to know what the graph means. Can it be a representation of the light distribution passing through the aperture (which is wide open at rest) ie a measurement of the amount of light coming off the subject?

digitalfx Posted July 26, 2015 Share #31 Posted July 26, 2015 It is from the camera wide open, the same feed going to EVF and LCD. The LCD and EVF don't display the actual exposure until you partially depress the shutter, but at this point the histogram is not visible. Link to post Share on other sites More sharing options...

Jeff S Posted July 26, 2015 Share #34 Posted July 26, 2015 I never even look at the histogram. My loss I suppose. No right or wrong, nor a badge of honor; it's just a tool, to use or not. For a critical shoot, it can be extremely useful (as can a hand held meter). For folks owning the Monochrom, for instance, having a RAW histogram in-camera can assist in avoiding blown highlights, as these would be unrecoverable in PP, unlike other color based Ms that might still have useable data through one or more color channels. Different strokes…. Jeff Link to post Share on other sites More sharing options...
ricky1981 Posted July 26, 2015 Share #35 Posted July 26, 2015 I very rarely use a histogram outside of Lightroom but it is a quite hilarious blunder to have messed it up in camera. It won't affect my enjoyment of the Q one iota (when it arrives) but someone in the Leica testing team (and all those photographers with early access) ought to get a gentle kick up the bum for missing that! On the upside, it should be a very easy fix in firmware Link to post Share on other sites More sharing options...
earleygallery Posted July 26, 2015 Share #36 Posted July 26, 2015 My Canon M has a function option for the LCD to show the image as it will be recorded, rather than the usual enhanced image for viewing purposes. Doesn't the Q have a similar function? Link to post Share on other sites More sharing options...
digitalfx Posted July 26, 2015 Share #37 Posted July 26, 2015 yes, but as I described earlier all the visuals disappear when you engage this by slightly depressing the shutter. Link to post Share on other sites More sharing options...
earleygallery Posted July 26, 2015 Share #38 Posted July 26, 2015 How did anyone take a decent photograph before the invention of the histogram?[emoji2] Similarly to how they carried out operations before the invention of anaesthetics I guess!

thighslapper Posted July 26, 2015 Share #39 Posted July 26, 2015 yes, but as I described earlier all the visuals disappear when you engage this by slightly depressing the shutter. yes ...... but as you half depress and release you get a fleeting view of the 'real' adjusted histogram but the little bu**er vanishes as the camera autofocusses. If you jiggle the shutter up and down you can see it quite easily..... Leica either need to let it persist with half depression of the shutter ...... or an option apply the estimated corrections dictated by the chosen iso/aperture/shutter speed settings to the initial histogram..... they can't be 'live' as the aperture is wide open initially Either would be fine .... but the former more logical in usage ...... although exp compensation is reflected on the histogram in realtime, just to confuse things ..... I suspect if you quizzed Leica they would say 'activate clipping ...... that's what it's there for .... what else do you need ? ' Link to post Share on other sites More sharing options...
viramati Posted July 26, 2015 Share #40 Posted July 26, 2015 I find the clipping and histograms to be of somewhat limited use even when they are linked to the actual exposure when they are based on the jpeg file and not the RAW as they tend to be very conservative in reference to the highlight range Link to post Share on other sites More sharing options...
