How ARW and PPM differ in practice

ARW files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to PPM 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.

ARW to PPM Conversion: FAQ

What are ARW files?

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 PPM files?

PPM or Portable Pixelmap files are image files included in Netpbm, an open source graphics program. The other widely used Netpbm formats are PGM (Portable Graymap) and PBM (Portable Bitmap). All three are image formats and are sometimes called collectively PNMs (Portable Anymap format). While PGMs contains grayscale images, PPMs include color images and they represent intermediary files used in the conversion of less known formats using the Portable Bitmap Utilities. PPM files are mostly operated on UNIX and Intel-based platforms.
