Anyone want to see the same photo, over and over and over again? Well here goes. A photo I recently took and the subsequent mess I made of it in Aperture once again looking briefly at Olympus Viewer. Now, Aperture works fine for me 90% of the time with the odd occasion when it's raw processing (and especially its defaults) fail to make any sense to me and this was one such time.

There were blown highlights in the OOC JPEG that I foolishly chose not to ignore (really, they weren't that bad when I eventually provided a perspective filter to my thinking) so I had a play with Olympus Viewer. Now, the lack of a recovery slider seems to be the bane of users of Olympus software but there are a coupe of strategies you can employ to get around this (and neither seems to have been discussed). I'll start with the OOC JPEG:



Aperture actually provides two tools that can help here. There are:

The curves tool, allowing you to reduce the raw exposure a little and then lift the mid tones (often with a small S curve to also add some contrast to the image) and here is the image reduced by 0.3 and then a reasonable boost the mid tones (and a little contrast)



Another approach is to reduce the exposure and then switch gradiation to auto. This produces a fairly flat image and there's a risk you blow things when adding contrast back in. So, with this image, in addition to gradiation auto, I've also applied a tone curve but very, very slight on the mid tones this time and then applying the small s at the bottom of the curve:



Points to note about this image: If you compare it to the OOC image, you can see the shadows of the building to the left are actually brighter, even though exposure is lower than OOC. You can probably get away with reducing the exposure by 0.4 or 0.5 to get more or less an equivalent image (albeit with cleaner shadows than if you'd made that decision behind the camera).

Another approach I've sometimes played with is to use Olympus Viewer as a very basic raw processor and let Aperture do the rest (usually on a TIFF). If you're looking at the greens, I switched the picture mode from vivid to natural as part of the raw development in OV:



Of course, this is where Aperture has some real advantages. A touch of darken highlights has improved the sky (especially the blue in the sky) no end and where my Aperture preset has caused highlights to be blown again, the recovery slider can be used to get these back with minimal impact on the overall image.

Aperture is a very competent raw tool in itself, so after playing with OV (and OV+Aperture) I went in and had another play:



If you're new to aperture and are having trouble getting to grips with what it does to Olympus raw files:
  • By default, it badly pushes the exposure
  • Click the auto exposure button and it over exposes then even further (there's your proof that ISO 200 from the E-30 onwards is really ISO 100, under exposed by one stop and then pushed - Aperture proves it by screwing it up)
  • Reducing the exposure slider by 0.5 gets your histogram to a similar ball park to that of the OOC JPEG
  • Other than that, Aperture profiles Olympus cameras and Olympus colours very well, albeit with slighter OTT greens.
Also worth noting is that Aperture's edged sharpening defaults come pretty close to the USM settings I used in Olympus Viewer (based on Scott Kelby's moderate sharpening recommendation - see http://www.photographyjam.com/blog/40/unsharp-mask-suggested-starting-values ).

the 1st shot (ocjpeg) looks the best to me. I'd say you had the JPEG parameters set up just about right, and I really don't see a significant improvement in any of the other photos. Might look different printed, or viewing full size on my 24" monitor, but here I think the 1st version is the best one.

The JPEG engine in the camera is great - any operation you do on the whole picture to recover highlights will likely have a small cost. I have a slight preference for the gradiation auto version (but only slight). I have no issues with using Aperture's defaults (notwithstanding the automatic over exposure) but prefer how Olympus renders greens.

Hi,

A very interesting post, have just seen it now.

Could you post a screenshot of your curve adjustments, I am just getting started with PP so I would be very interested.

Many thanks!

I can’t see much wrong with image one that would tempt me to play around with it other than the top of the tall building merges totally with the sky which I would find very annoying. Surprisingly you don’t seem to be worried by that. As for the rest of the pictures I can’t see hardly any difference between them and if I had to vote I would go for number one. I like to see posts like this because it definitely you think.

I don't know if they're worth the time - they don't add much to the image IMO.

However, allow me to express a concern of different kind: WB.

I find there is a slight magenta cast which reduces the IQ of an otherwise fine landscape shot and this cast has propagated to all the different versions of the image.

If you happen to have PSP X2 (maybe X1 will do too) try either the one step photo fix or the smart photo fix and see how it looks.

I haven'y got a clue what I was talking about there, that was my work monitor and at home it looks fine. Just goes to show we can probably achieve most improvement by buying a new monitor.

I do not use Aperture, I use Lightroom instead, but I think the strategy would be similar.

Yes, I also view my photos over and over. It's like a full time job I do for my photos, so I also noticed the problem you mentioned, that's why I have my own presets for Lightroom.

If you haven't gone to Wrotniak's site already, he made some suggestions that only after a few years of PP, I realized why (he didn't bother to explain, he only said it's the best setting). I couldn't find the original articles that described it (it's in the middle of a long list of his many articles about 4/3), but do a -1 on sharpness, and contrast also by -1. The first part is only to normalize the sharp (by default Olympus Viewer sharpens a little too much, don't worry, you can resharpen it with Aperture/Lightroom, as under those suites the sharpening is much more subtle and sophisticated). The lower the contrast part is what you are asking for, to recover the highlight. Yes, by default the Olympus processing is very punchy, which is fine if the scene is low DR or normal range of contrast to begin with. However, if the scene really pushes the capability of your 4/3 sensor by using a borderline high DR and/or very contrasty lighting, then you have to lower contrast level, and then fine tune with Aperture/Lightroom.

This is what I do.... If I remember to lower contrast when I see the light in the first place, I alter it in camera. If not just develop RAW with Olympus Viewer and lower the contrast by -1 (or -2 if it's really serious). Yes, it'll look flatter, but you get to retain Olympus color. If that's not enough, save the file as EXIF-TIFF and port it back to Aperture/Lightroom. Instead of using recover, flatten the tonal curve (if it's not already "linear"), lower the contrast to -25 (in Lightroom 3, I don't know what's the setting for Aperture or Lightroom 4, but I think it means -25% lower contrast). Boost black slider to 12 (if you want punchier color, use 18), and then fine tune your exposures. I use brightness instead of exposure slider in Lightroom 3. I think they combined them in LR 4, which probably means I have to change my settings all over.... Brightness and Exposure sliders are NOT the same!!! Brightness "shift up" the exposure curve, and no change to over all histogram curve. Exposure will change the tonality. Different method of brighten the photos up. The combination of black slider and brightness slider will shift up the exposure without changing the tonal curve, and that's what we want to preserve highlight.

For your situation, it's only cloud that's giving the problem, you can also use "graduated filter." I don't know if Aperture has it, but basically it emulates "Graduated Neutral Density" (GND) filter. You just darken the top portion of the image (the sky and cloud portion), so the lower portion remained properly exposed. You can also lower contrast on the top portion using that tool to preserve highlight without lowering the contrast of the bottom. It's an indispensable tool in Lightroom.
 
Given OP's very keen eye on the highlight issue, I think he is a pro and probably fine-tuned his monitor. In my fine-tuned monitor it also looks fine (try observe the white part of the cloud and the boat). I think it's the lighting condition. I think if he warmed the image slightly, the issue you mentioned would be reduced. The default setting for each graphics suite is slightly different. He uses Aperture, so maybe that has something to do with it. With Lightroom, after I created a default color profile using Colorchecker passport, it actually makes each photo slightly greener (the opposite end of magenta cast spectrum) so maybe that's the offset required to make the photo slightly more natural.... Converting from AdobeRGB to sRGB will also introduce a magenta cast, btw, if some color is outside of the color gamut.
 
Since writing this, I've played a little more with exposing to the right and then employing highlight recovery by reducing exposure and then using auto gradiation to bring the shadows back. It can work quite well on the kind of bright, mid summer afternoon that isn't good for taking photographs.

In the meantime, Apple have improved the way Aperture handles Olympus raws by default. I had an entry for my rarely updated blog ready to go but alas, a little thing called day job got in the way.

Edit: If you're starting out with Olympus and don't want to invest in software, Olympus Viewer is well worth a try IMHO. It may not have a recovery slider but it does at least supply ways around that.

In viewer it's hard to recover highlights, but the curves tool can help a little. Just pull the top down a hair and keep it straight. You can also reduce contrast, then boost it later in lightroom or aperture. Also a few clicks of the "warm" filter seems to help for some reason.
