> Reviewing an older text regarding museum preparation of specimens, I ran
> across the following procedural reference:
> 	Wash the specimens in running water to remove any residual fixative
> 	Transfer to 95% alcohol, anywhere from 1/2 to 12 hours- watch the
> specimen carefully;
> 		the alcohol will bring back the color, but if left too long
> it will fade away (irreversible)
> 	Remove from alcohol, blot dry and photograph
> 	Transfer to a storage medium (1416g sodium acetate, 4L glycerine,
> bring to 10L final volume)
> 		for long term display- color won't last forever, and sample
> will float until it is fully permeated
> 		with the glycerine solution.
>
> Otherwise, I would think you could process the specimen after photography
> (keeping in mind that it may not be fully alcohol dehydrated during the
> color development- it may need more time after photographing).
