EX2f Raw development

Hi: I used to own an EX1 then sold it. I regretted it for it was a good easily carried camera. Now I've just got an EX2f replacement but have a question about Raw development in Lightroom. I'm not getting the same quality results as I did with the EX1.

Could anyone share their typical setup please.  For example, for my Olympus cameras the Black level usually is around -20, Contrast +20, Clarity +20. Sharpness +40 and so on. But images from the EX2f seem to respond very differently with Clarity and Sharpness not appearing to have the same effect. Black level seems best left at 0. The various setting seem to behave very differently to what I'm used to.

Also, Lightroom has a built in compensation for the EX1 but not the EX2f. Does anyone use the EX1 setting? I haven't 'played' enough to see if it is a benefit or not.

Any help would be appreciated and could speed up my learning about getting decent quality images from the EX2f.

Thanks

Donald

OK - so where to begin.

Although the EX2F is a wonderful enthusiast model (well, I think so), it does have its limitations in DR.  And at times, I've discovered that the best way to save hi-lights is to set your metering to Averaging (not the multi-segment variety).  If you are going to use the multi-patterning metering, it's best to dial in anywhere from -.3 to -.7 exposure compensation.  You'll find it's a bit easier in bringing up some of the shadows than it is to try and save the hi-lights.

OK - having said that, here goes.  The key to remember is that folks often overdo it with various settings in lightroom.  In other words, too much PP'ing can overdue the results and end up actually altering an image so much that it can appear ruined.  Thus prompting some folks to retort that somehow the IQ is not good enough.  One area that can be affected are trying to back off the hi-lights too much, thus actually introducing a purple tinge into the image (mass purple fringing effect?)  That's because the hi-lights have been lost to the point that trying to bring them back even further introduces this PF effect, so you have to be careful.

The DR scenario is a biggie and first of all, I keep my EX2F settings as follows:

1.  METERING:  Sometimes I keep it on Multi-pattern metering, but dial in anywhere from -.3 to -.7 exposure compensation.  They key here is to save the hi-lights.  The algorithms in the Samsung EX2F multi-pattern metering.  Other times I select the center weight average metering because for some situations, the hi-lights are better saved.  It's your call and only experimentation will work here.

2.  ISO:  I try to keep mine set to ISO 80 or 100 - but usually not more.  Thje EX2F isn't particularly a hi-ISO champ.

3.  AF FOCUS AREA:  I keep mine on Selection AF, meaning I can move around my AF point as I set fit (although the actual AF window is a bit small).

4.  IMAGE ADJUST:   I keep my contrast set to -2, my sharpness set to 0, and my saturation set to 0.

I tend to shoot RAW only and my editing software of choice is either Lightroom or mostly ACR within Photoshop.  Since most of the settings within both Lightroom and ACR are the same, here is what I do - keeping in mind that these are general settings, meaning they may vary from photo to photo.  Because weather conditions can change what you need to do with your RAW file.

I will provide some sample files below.

The Basic Tab:

1.  Look at your color temperature.  Although most cameras have very good AWB settings, some may render images either too warm or too cool for a given scene and lighting.  Sometimes you may have to move the slider to the right a bit - especially during bright, clear sky conditions.

2.  Exposure - as needed (but first try to adjust hi-lights and shadows with their respective sliders).

3.  I don't mess with the white or black sliders at all because all this does is to lighten or darken them.

4.  I stay away from clarity unless I absolutely have to, because clarity is similar to a sharpening scenario and can add noise and/or glitter.

5.  Saturation - add only if needed, meaning if your image is very flag, add saturation accordingly.  I typically add only +10 to +15.  If it still looks a little flat, I then add a big of vibrance - but don't overdo the vibrance as it can lead to very unnatural scenarios.

The Sharpening Tab:

Here's where most folks will screw up an image, either making the sharpening overly unnatural, or may not add enough.

Sharpening amount:  I go no higher than 35 (read below under detail).  I typically set it default to 35.

Radius:  I keep it at 1.0

Detail:  Now here's the secret that many folks don't know about.  Oftentimes, folks go nuts with their sharpening amount above - with the resultant problems being that halos appear around items in the scene.  With detail, I typically always set it to either 50 or 60.

Masking:  Keep it at 10 - because raising it will soften an image.

Luminance Noise Reduction:  I typically set +15 or +20 in good, clear days - but as high as +25 or +30 on darker, cloudy days which can cause noise in many of the shadow areas.

Luminance Detail:  I usually leave this alone.  Same with Luminance Contrast.

Color Noise:  Now here's the kicker - Adobe sets the default at 25.  I always move this slider back to only 5.  Why?  Color noise can, in some cases actually try to blend the colors of similar items and I've seen instances in where in some scenarios, very small items (i.e. leaves) can be lost if this is set too high.

Color Detail and Smoothness - I typically leave this alone.

Lens Corrections Tab:

Click on the profile tab and make sure that "Remove Chromatic Aberration" is checked.  Then go over to the "manual tab" and adjust your purple fringing tab anywhere from 5 to 8 (sometimes you have to choose a higher setting due to lots of PF in the scene).  Then come down to the vignetting area and slide the "amount" slider slowly to the right and check your corners to make sure their lit properly.

Effects Tab:

Now here's a little weapon that many folks don't know about.  If you have weather conditions where it's overly bright and hazy (or no haze, but very bright), adjusting the Dehaze slider can make the blue in the skies darker (almost like a polarizing filter).  But you have to watch the whole screencarefully because it can darken your shadows a bit also which you may not want.  I love this particular tool, that's for sure - but you have to be careful because it can introduce entirely too much contrast.

Some EX2F image samples taken with the settings mentioned above.  All Images were shot in RAW mode, AWB, Aperture Priority (ranging from f3.5 - 4.5) - IS engaged.  Conversions were made within ACR.  Batch framing were added to the web samples using IMBatch software.  Web JPG's were created at a 90% quality setting and resized to 1600 x 1200 (I don't post full sized images because it can get irritating).

Re: OK - so where to begin.

Hi Ben: Thank you, very useful. I will have a play with the in camera image settings. In terms of exposure I'm finding that I need to dial in about +1/3 of a stop.

In Lightroom 6 I use the Highlight and Shadow sliders a lot and usually adjust Black level for these are all very useful in my Olympus images. EX2f images don't respond to Black level adjustments so well. Agree on Sharpening, it is easy to overdo it. I've been setting Sharpening at 40, radius 1.5, and Detail about 70ish. At ISO 80 I've been setting Luminance around 40 +/-. I must look at the Colour Noise although I haven't noticed too much. I have noticed the need to Defringe quite a lot. I find that more Clarity is useful.

I find it odd that the image adjustments in camera actually do things to the Raw file, never come across this before - Raw files are supposed to be raw!

A weird thing happens with digital zoom which I played with. It appeared to work when I imported the image into Lightroom, but then the image suddenly reverts to the optical zoom size. I.E, digital zoom doesn't work properly in Raw. I will investigate further for I've never had Lightroom change the metadata like this before.

It's a fun little camera and it is a great pity that Samsung quit. Anyway, you have given food for thought and I will continue working away at getting things the way I want.

Thanks.

Donald
