أقنعة سالب كايزر - 4.5 × 6 سم

I was a little worried about compatibility with my enlarger’s compound carrier, but this 4.5x6cm insert went in with zero fuss and holds the negative dead flat. The metal edges are clean, so no stray light leaks through, which makes focusing noticeably easier. Exactly what I needed for medium format

Switched to these masks for my 4.5x6cm negatives and the fit in the carrier is absolutely precise—zero light leaks or shifting. Really cleaned up my contact sheets.

These masks slide perfectly into my enlarger's negative carrier and hold the 4.5x6cm frames flat without any shifting. I've been using them for a few weeks now and the precise fit makes focusing consistently easier.
