RX100 - BLOWN HIGHLIGHTS

Yes, the RX100 is good, but does have less dynamic range than a large sensor camera with much bigger pixels. But if you shoot RAW, you can still extract a lot from the images. Here's a hand-held, available light one I took in a lab, with shadows and bright lights, which I think the RX100 handled well.


RAW image processed using Dxo; both highlights and shadows adjusted.

had a hard time with blue sky snow capped mountains with darker lower areas. using std HDR/dro helped only a little bit. I didn't play with different dro levels. I was so busy shooting the magnificent scenery I didn't pay a lot of attention to the basic I learned long ago: meter the bright area and lighten up the dark in pp, but most were usable with a little LR and PS
 
Guys, I really recommend using the Auto HDR Option. Especially in good light, you will get crazy dynamic dange and no blown highlight. Even a lot of movement is not a problem in good light. I always switch between auto DRO (Quick shots of people) and auto HDR (landscape or Scenes like the tram). I even prefer it to shooting raw.

In night, it can also give superior results but because of the lower shutterspeed, sometimes the HDR produce ghosting...

I think the problem here is that we take the 'DSLR in your pocket' idea behind the RX100 too literally - these cameras really can provide DSLRS-like images but not all of the time, and they can't compete in terms of DR with APS-C or FF sensors. Compared to smaller sensor compacts the highlight clipping is no worse or perhaps better, but compared to larger sensors it is noticeably worse. I find shadows can be worked up quite well in raw but clipped highlights not so much. It's a compromise you have to live with - even the larger micro 4/3 sensor in older generation cams like the G1, G3, etc., suffered quite badly with limited DR and highlight clipping. I'm yet to come across the perfect camera with no compromises...
I think it is instructive to take a look back at what we considered DSLR performance in 2006 and compare the RX100M2 with the A100.

http://www.dxomark.com/index.php/Ca.../(brand)/Sony/(appareil2)/216|0/(brand2)/Sony

Take the DXOMark scores with some salt but at face value, the RX100M2 is remarkably close to the sensor performance of the A100, surpassing it in DR by more than a stop (12.4EV vs 11.23EV). Even the A700, though superior at more things than the A100, still has an inferior DR (11.93EV) to the RX100M2.

I do find it slightly more difficult to meter high contrast scenes than with my NEX-7, and I tend to dial in -0.3EV or -0.7EV on the RX100M2 as insurance. Still, I am amazed at just how far sensor performance has progressed in just a few years. Who would have thought a 1" sensor would match the dynamic range of a "full-frame" camera (the still highly regarded A900, 12.31EV)!

http://www.dxomark.com/index.php/Ca.../(brand)/Sony/(appareil2)/371|0/(brand2)/Sony

Of course current APS-C and "full-frame" sensors have about a 1-2 stop advantage in DR over the RX100M2, but it wasn't too long ago we were very pleased with DR over over 12EV.

Cheers,
Daniel.

You can also see this at work on TV if you watch live coverage of a sporting event or parade or some such on a sunny day. In the case of a team sporting event, as the players that the camera operator is tracking move into a shadow area, everything outside the shadow area becomes a sea of white. If the players move into a glaring sunlit area everything in the shadow area becomes a sea of black. The critical task is to keep the players properly illuminated, and that's what happens, except for a second or two of transition.
That's one of the places where DRO is so good and an advanced DRO equipped camera does much better than is being described here.

The dynamic range can be tested to be a specific value, but that's not how it has to be used. With modern software like DRO one can modify the dynamic range curve to match the scene. That's how our own vision has so little blown highlights. It uses the same methods that were learned from it to invent DRO to avoid constant blown highlights. It remaps dynamic range point by point.

So, better understanding of the settings of things like DRO and their limitations can help. Also realizing that even DRO is not as good as our own eyesight will explain a lot.

Helps to also realize that the dynamic range of the camera's sensor is only one of several dynamic ranges you are dealing with. The light that's lighting the scene, the display you use, each piece of PP software, the print if you print it and so on all have their characteristic dynamic range. Any one can throw you off, or the combination of all.
 
Not the camera... The RX100 has a relatively large dynamic range, unless you go below ISO 125. Need to expose the shot properly in the first place, and then do needed post processing to fine tune it. Blown highlights are blown forever, and can't be recovered. While it is nice to expose to the right (higher side), if you go too far you are toast. If not sure of exposure and the highlight areas are important to the shot then better to underexpose a little, rather than overexpose.

Some quick touch up with ACR. The front corner of the car is blown. Rest could be recovered.

I've been experimenting today with different -EV settings on the RX100, but the resulting shots vary from looking ok to being way too dark, even at the same EV settings, but as you say it's better than blown highlights. When I shot the above photo I'd only purchased the camera 48 hours earlier, so unfortunately had not had the chance to do any extensive testing before the photo shoot.

It's interesting to see how much colour can be recovered using ACR, and also that all the information has been blown out on the the front corner of the tram.

I think it's a bit harsh to intimate that concerns about blown highlights are just the fault of the photographer. Folks can quote DXO data or whatever numbers they want in relation to the RX100 MK1 and MK2 dynamic range, but even though I have used DSLRs, micro four thirds and many different digital compacts, and used to shoot with film, I initially got caught out by the tendency of my RX100 mk1 to clip highlights more easily than the other cameras I currently shoot with (Sony a57, a77 and Panasonic GH3 and GX1). I was reminded of when I first got into micro four thirds - the first 12MP m 4/3 sensors/cameras (e.g. GF1) clipped highlights very readily as well. In bright conditions this can be a tricky issue because you may find yourself having to boost the LCD brightness using the sunny setting. If you do that, the brightness of the playback image is not a correct reflection of the final captured image, nor is the liveview, so dialing in minus exposure compensation does not necessarily work out in a straightforward way.

Like any camera, it takes time to know how to get the best out of the RX100, but highlight clipping was one of the first things I noticed when reviewing my first few outdoor shots - that and unbelievable resolution :-)

I recommend you shoot RAW, Alan. I always shoot RAW + JPG - the JPG is there for convenience but I always have the RAW to fall back on if I need to get more out of an image.

Have a look at this post as an example of highlight recovery on the RX100. RAW on it's own might have been enough to save the above image.

When looking at -EV settings always remember you can recover more from shadows than highlights on the RX100, so better to err on the side of underexposing a little. I've seen posts where people just leave their RX100 on -1/3EV for this reason.
 
With this composition you'll get blown highlights with most cameras every day of the week. Shooting with the low sun almost directly behind the camera will almost always result in a poor outcome. Reversing the lighting position and using fill flash would make a big difference. Lots of shots like this can be fixed in PP.
 
... where's the O.P.?? Three days ago he provoked a discussion on a problem most probably non existent ( I have the RX100 since November 2012 and never had that problem ) and never came back!

I believe that just the opposite is true. IMO low sun, behind the camera is one of the conditions that I think can often lead to a great outcome. This page from the instruction sheet for my first camera, a Kodak Baby Brownie Special, shows the ideal position for picture taking, minus the cigarette ;-).

Actually, with the sun low and behind the camera, I generally get great, warm lighting. Blown highlights is rarely ever a problem in such a situation as well.
 
Clipped highlights, be it from the RX100 or any other camera, is a function of the photographers inabilty to work with his equipment to create the outcomes he desires.
 
This example does not suffer from nearly any loss of details. There's no real washout only some color shifting from cream to a lighter shade of cream. This is mainly due to the light reflection and a polaroid filter would have probably eliminated it as someone in the thread have already suggested.

As it is, a bit of selective color adjustment solves 99% of the problem IMHO. I took the liberty to give it a go, hope the OP does not mind:



selective color (white) adjusted

This thread was started by me on behalf of a friend, Alan Robson. He has grabbed the baton and responded twice to the thread. Therefore what is you problem?

I think you need more basis to make that criticism of the camera, than a single photo of a very light colored object against a dark background. If you do not meter for the light colored object then of course you will overexpose it. Has nothing to do with the camera that I can see. Following is a quote from the Imaging Resource site:

"Total dynamic range came in at 12.3 f-stops, a hugh improvement over the JPEG's 9.63 f-stops, and better than a quite a few SLRs and CSCs with much larger sensors." No indication that this camera is more tricky to handle when it comes to highlight clipping.

http://www.imaging-resource.com/PRODS/sony-rx100/sony-rx100A5.HTM

If you want to preserve dynamic range, expose for the highlights you consider important, and use RAW. Or if you don't mind the fake flattened look of HDR then shoot HDR JPEG.
