Default RawTherapee for Panasonic Lumix FZ 18, poor results

I have realized that JPEG taken by the camera (Lumix FZ 18) are far better than the ones obtained by processing the RAW files with RawTherapee, no matter the pre-defined profile I use (neutral, punchy, default...)

When I compare on the screen both versions, the original JPEG have more detail and vivid colours. I even notice than shapes are changed in some way.

Is there any Lumix user working with RawTherapee that could me give some advice?

G'day mate

Firstly - Welcome to Steve's - there's lots of fellow photographers here who are happy to assist you in various ways

For me - I use both Panny & Fuji systems, but I do not use RAW at all, so I can't help much today

I am happy with the results I get via JPG

I have used Panny's RAW files several times... purely for experimental purposes... though to be honest there really isn't much latitude for adjustment given the small sensor used.

I have Raw Therapee- though I use Silkypix for the Panny files... which was the supplied editor.
The Silkypix is a decent editor- as is Raw Therapee- but the Panasonic jpeg engine pretty much squeezes the most out of the available data,producing nigh on optimum jpeg output.
What I will say for the Silkypix editor- in RAW default settings the colour is extremely accurate- and the biggest area available for manipulation is sharpness/noise reduction.
Panny's jpegs tend to be a little noisy- and this is where I tend to make the most adjustments- with in my opinion, much "cleaner" results achievable by shooting RAW.

Raw Therapee's default settings for a RAW file is too sharp- with very enthusiastic base settings. As such,If I use RT' I click off all the adjustments and go from scratch- though again,I mostly focus on noise reduction.

As far as dynamic range goes- neither RT or SP offer any advantage over Panny's jpegs...

I don't have any Panasonic cameras. But, you may want to try some of the other Linux apps to see if you get better results. If you want to stick with Open Source Products, you may want to try DarkTable and RawStudio. LightZone may be worth a look, too.

Personally, I use Corel AfterShot Pro (commercial versus open source) for image management and raw conversion in Linux (and they also offer it for Windows and OS X). I have loads of image management and editors installed in Linux (incuding Raw Therapee, UFRaw, DarkTable, RawStudio, digiKam, etc. etc. etc.).

But, IMO, nothing comes close to AfterShot Pro overall (as it's a super product for image management and basic editing tasks, and it's very fast). So, in it's case, I don't mind spending money for it versus the Open Source alternatives for the way I manage my workflow (as it's a huge time saver for rating and culling images, using it's metadata browser features to find images imported into catalogs, etc.; and has loads of [non-destructive] editing features, too -- even including features like layers with edit regions so you can apply adjustments easily to selected portions of an image only.).

They've got a super sale price on it right this minute, offering it for only $24.99 (and I have no idea how long it will last, as I suspect it may be a Black Friday type of deal or something, as I did notice an e-mail about specials on products since I'm on their mailing list).

http://www.corel.com/corel/product/i...id=prod4670071

That's a U.S. Price though (it may be much higher in other locations).

They offer deb and rpm files you can use to install it, depending on the type of linux distro you use. You'll see links to them on the download page. If you're using a distro that uses .deb files (Debian, Ubuntu or derivatives), you'll need to select the 32 bit deb for a 32 bit distro, or the 64 bit deb for a 64 bit distro. For distros that use rpm packages (OpenSUSE, Fedora, etc.), the same rpm is used for both 32 bit and 64 bit distros.

http://www.corel.com/corel/pages/ind...?pgid=14400019

It works for 30 days without buying it. Then, if you decide to buy it, you can just plug in the license key you get with no reinstall needed. But, I don't know how long that sale price will last (as $24.99 is the lowest price I can recall seeing them offer it for in the U.S.). IMO, it's a "steal" at that price (even if you used it with jpeg files only). It's very fast with loads of features.

Here's a "webinar" that goes into many of it's features (it's based on an older version and some of the features have changed, but most of the options are still the same). I'd suggest watching it to get a better idea of what it can do (as it has a lot of features that may not be obvious at first glance that the webinar goes into).

On the Open Source side, DarkTable (see link to it's product page above) has loads of features available (including multiple modules with several different types of noise reduction). See it's online user guide here to get a better idea of what many of them can do:

You'd have to try it on the files from your FZ18 to see how well it works with them.

Hey, Simon and Jim, I really appreciate your help.

I am giving Darktable a try right now, it looks promising, I will write here my experience one of these days.

Cheers.
