Three fixer test

Recently i bought Amaloco x-89 rapid fixer as i was wondering if it would work with Collodion. Well it did, and i was surprised by the result.
Is it a scientific test. NO !  but i tried to show you the differences using three different fixers.

The result ? Well they are close to each other. The KCN gives a bit more yellow look.
Can you call it warmer ? Maybe, but the differences are really close.

The other two show a little bit more magenta/red tone. But again, it's close.

Just one remark. It looks like the KCN also has a bit influence on the exposure ???!!!
It looks just a tad brighter.

If you make two identical pictures (which is almost impossible with collodion) and you lay them side by side you might notice some difference. But when showing just a single plate for me it is almost impossible to tell wich fixer was used.

From left to right
1. Amaloco x89
2. KCN fixer
3. Natrium Thiosulfat (HYPO)

First i precutted a plate so it was easy to break it after the developing stage.

 Three fixers. from bottom to the top : Amaloco, KCN, Natrium

After developing 

Again, from left to right : Amaloco, KCN, Natrium Thiosulfate
Plates were still wet.

when dry the diffence is even closer.
