I personally know Mike the owner of Capital Color.
The lack of E-6 business is why he closed.
Expensive is a relative term, for Mike provided a service to the DC area's top professional photographers. He provided the very best customer service around, with color accuracy that few labs could match. For that we all were willing to pay that little extra over his competition.
Mike said he would been happy to continue working as long as people need E6 service, but the professional market shifted so quickly to digital, that he knew it was time to retire.
He invested wisely, so don't worry, he and his family are cared for.
