How ARW and DCM differ in practice

ARW files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to DCM bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after.

"I inherited a huge archive of ARW files and had no idea how to open them. None of my usual programs would recognize the format. reaConverter saved the day – in just 30 minutes, I recovered the entire archive and converted everything to JPEG. Now my photos work perfectly on phones, computers, and messaging apps. The software is incredibly user-friendly – what a lifesaver!"

ARW to DCM Conversion: FAQ

ARW is the proprietary format used by Sony cameras to create and store RAW image files — uncompressed images which can be later on adjusted using image editing software. RAW images are popular among photographers because they allow an advanced degree of customization during digital post-processing. However, ARW files, like most RAW images, tend to be very large in size, which makes them difficult to store and transfer.

What are DCM files?

A DCM file is a DICOM file, meaning it follows the Digital Imaging and Communications in Medicine (DICOM) standard for storing, transmitting, and managing medical imaging data. This standard ensures interoperability between medical imaging equipment and software, allowing images to be shared across scanners, servers, workstations, and network systems.
