Sweet Yellow and Light Red Collodion Comparison

Here are 2 collodions I mixed up in the last week. The red one on the left used old USP collodion that was about 1 1/2 years old. The yellow one on the right is from fresh USP collodion. I know the yellow will work great, not sure on the read. Possibly more contrasty and definitely slower in speed.
