<p>Try Duggal, on 23rd St. between 5th and 6th Aves. They did a beautiful job on my daughter’s portfolio, which included b+w digital scans and color scans. They even photographed several models and sculptures.</p>
<p>There are also many other professional photo labs in the Chelsea neighborhood, all on the side streets between 5th and 6th Aves., between 23rd St. and 16th St. Since they all cater to the professional graphics/architecture crowd, they are open late and on Sats, some even Sundays. Wander around and talk to them and ask for samples of their work.</p>
<p>Be prepared, though. What you are proposing to do is not cheap.</p>
