XZ-1 Samples using RawTherapee and...
Feb 2, 2011

Hello,

The RAW converter used makes a big difference. I think it was Oluv who pointed at the excellence of RawTherapee (RT): I stopped using it a while back because of constant changes.

I decided to revisit RT: By default it produces terrible colors (IMO) compared to the Oly JPG Colors. Then I came accross these Profiles:

All the Olympus ICM profiles seems to give colors close to the XZ-1 JPGs, so I installed "Huelight_EP2_v4.icm" into RT: Voila, the Oly colors are back!

Below is the orignal image taken from Oly Viewer 2 from this thread:

See the differences?

Thus, when discussing Image Qualilty, you cannot only blame one factor e.g. the lens, but have to consider all factors in the chain that produces the image: The RAW to JPG engine is one of the important factors.

I am amazed at what I can get out of RT and still keep clean pictures.

The XZ-1 is a gem in my opinion: You can get the details you can expect to get from a tiny sensor if you put your mind to it:

I have created a profile in RT (not icm profile), that loads the settings and the ICM profile, and voila RT can Batch Process my images and produce sharp Oly Colored JPGs that I import into LightRoom
