comparison of raw and jpg for spectroscopy on C Buil website

Post by Robin Leadbeater »

I know somewhere on Christian's website there is a comparison of spectra taken using raw and jpg images from a DSLR. Does anyone know where it is? It shows clearly why you should never use jpg. The loss of resolution is very clear.

Thanks
