Technical note

NEF to HPG: what carries over and what does not

NEF files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to HPG 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. A line in an NEF image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the NEF does not survive as colour in the HPG.

I'm a beginner with a Nikon D3500, and I didn't know what to do with NEF files. reaConverter walked me through the conversion process with its simple UI. Now I have JPEGs that I can edit and share. This software made photography less intimidating.

Nikon's NEF files are legendary for quality, but they're huge and proprietary. reaConverter converts them to JPEG with stunning results – the dynamic range is retained, and the colours are spot on. I've processed over 10,000 NEFs with this tool and never had a glitch.

Our photo studio uses reaConverter to convert NEF files to TIFF for printing. The batch processing is reliable, and we can apply custom colour profiles during conversion. It's saved us hours of manual work and improved our print consistency.

I had a hard drive full of NEFs from a decade of shooting. reaConverter batch‑converted them all to JPEG with a single click. The older files were processed perfectly – even the ones from my first D40. This tool is a time machine for my photos.
