Raw capture

Android 5.0 Lollipop is the first Android version that officially supports Raw capture via the Camera2 API. The DMC-CM1 is only running Android 4.4.4 but can still record Raw files, presumably thanks to clever Panasonic engineering. And the .RW2 files offer noticeably more leeway in terms of dynamic range than the Raw files from smartphone camera with smaller sensors. The JPEG image below was slightly overexposed, which resulted in some serious highlight-clipping in the bottom left corner. We applied some negative digital exposure compensation to the Raw file in ACR and also adjusted the highlights. As you can see this measure results in a lot of recovered highlight tone and an overall more pleasant exposure.

The image below was captured in low artificial light, resulting in a strong warm color cast. In Raw conversion we adjusted the color temperature and tint and slightly lifted the exposure, with all other settings left at default. As you can see in the 100% crop the image shows noticeably stronger luminance noise, but on the upside there is also noticeably more detail. Color is more neutral as well.

iART effects

Photo Styles only slightly fine-tune color and tonality of your images, but in addition to those modes the DMC-CM1 also offers a range of more extreme effects called iArt filters. Most of them, for example Impressive Art, Bleach Bypass or Star Filter, don't offer any manual fine-tuning, but Point Color allows you to select the tone you want to isolate in an image and Miniature Effect lets you move the focal plane in the image to create a tilt-shift effect. Some effects slow down the frame rate of the live view image, but they can be combined with Raw capture. That way, you still have a backup Raw file if you change your mind about the applied filter later on.

Front camera

The front camera is not one of the DMC-CM1's strong points. Its HD resolution images show very little detail compared to the 5 or even 8MP front snappers on the current crop of high-end smartphones. It is capable of capturing reasonable exposures even in low light, but noise levels rise quickly as you can see if click through to the full-size samples below. Overall, the front camera serves its purpose in video calls and when capturing the occasional bright-light selfie, but don't expect any print-level quality.

Gallery and editing

The Lumix gallery app is capable of displaying the CM1's Raw files.

The CM1 comes with Google's Photos app but also has the Lumix Gallery installed. The app doesn't offer much above and beyond the standard Android image viewer but is capable of displaying the CM1's Raw files and basic EXIF data for each image. If you'd rather not see Raw images you can opt for JPEG files to be displayed only.

Basic Exif data

Other than that, the Lumix Gallery is a pretty standard gallery app. You can sort images by album, location or date and share them with any other installed apps that can process image files. The editing module offers the usual options including some basic frames and filters, cropping, vignetting and a decent array of tonal modifications such as curves adjustment or highlights and shadows. Raw images cannot be edited in Lumix Gallery.
