Sodium homepage photo collage

Microphone cutouts: supplied by the project owner; locally masked, cropped,
converted to monochrome and optimized. Original files are preserved.

Headphones: derived from the existing headphones-original-cutout.png site asset.

Instrument cutouts were traced locally with rough paper-cut borders,
with backgrounds removed and original printed detail retained. No performers,
ImageGen or other generated imagery were used. Paper grain is SVG artwork;
the blob and star are Sodium's existing brand shapes.

ARP 2600 synthesizer: catalogue scan by Chris Carter, reproduced via SOCKS.
The reference archive gives a possible period of 1976–1982; this is later
analogue equipment, not a claim that the synthesizer is from the 1960s.
