I have a photograph (the negative has been lost) that I want to enlarge to 4x6, it had been done before at an in-house lab and was good quality using an interneg process- not very grainy and the colors were magnificant. It was destroyed in an unfortunate moving accident and I need to replace it. I brought it to Robyn color and the test strip using a digital enlargement was horrible and they told me the interneg would be worse. So I am willing to spend however much money it costs to have a good one made but Robyn came as the highest recommended place in the Bay Area. But I don't know much about any of this and don't know if what they say is true, can someone recommend a process and place anywhere in the US that I can use, preferably in the Bay area- but am willing to go elsewhere for higher quality. Thanks !!
