First glimpses of Pen E-P1 RAW image potential
Today, Olympus released updated software to that is compatible with RAW files from the Pen E-P1. I've spent an hour or so processing a couple of E-P1 RAW files taken at last week's European product launch event in Berlin.You can have a go, too, as we've made over sixty images, in both RAW and JPEG form, available for you to download.
Below, I have included my attempt at processing two RAW images from the download gallery, one a portrait of the Pen E-P1 girl, Penny, and a 6400 ISO low light shot. The latter does, in my view, confirm that the Pen E-P1's new TruePic V image processor is significantly better at managing noise at high ISOs, with ISO 6400 being usable for some applications and being far from a cynical marketing exercise. But let's start with Penny:
Original Pen E-P1 camera JPEG image file. Click image to open full resolution file.
Above is the camera JPEG. Click on the image to download the full size original camera JPEG. This was taken at ISO 100, with the camera's noise filter switched off. The m.Zuiko 14-42mm standard zoom was used, at f/5.6 (widest aperture) using a focal length of 42mm. The shutter speed was 1/400th. Aperture Priority auto metering was used, via ESP evaluative mode.

And here (above) is my result from using Olympus Studio 2.3 to process the RAW file. I've gone for slightly more saturation, darker blacks and increased contrast using the tools available in Studio, including the curves tool. Click on the image to open the full resolution JPEG file produced from the RAW file by Olympus Studio 2.3.
Both the camera JPEG and the Studio-produced JPEG are in sRGB colour space, but you can also have a look at the same image produced from the RAW file in Adobe RGB space.

This image (above) was shot using ISO 6400, hand held. The camera has brightened the scene from that I recall seeing with my own eyes. To demonstrate how dark it was, the camera only got as high as 1/30th second shutter speed even with ISO 6400 sensitivity. The 14-42 lens was used again, this time at 22mm, or mid way through the zoom range, and the aperture was f/5.6. The camera's noise filter was switched off. Click on the picture to open the original camera JPEG file.

And this is my effort at processing the same image, but from the RAW file using Olympus Studio 2.3. The noise grain has been suiccessfully suppressed and although the image does have a softness about it if you look closely, as you can see here it works surprisingly well at Web resolution, and will be fine for small to mediun sized prints. Click on the image to open this picture at full resolution. You can also download the matching RAW file.
Do try some RAW files for yourself and let us know who you get on.
