Otto is willing to do a lot of the legwork to put together this Studio Artist focused exhibit, including dealing with the details of the printing and framing of the artwork locally for the show. So my understanding is that artists just need to submit digital files of their Studio Artist generated artwork to be used in the exhibit.
Otto invites artists to submit Studio Artist images of photographic quality, picking them for 'photographic clarity'. Here are some guidelines for artist's submissions.
5 work samples (jpgs) up to ½ mb each, 300 dpi, 4x6 inches (1800 x 1200 pixels), landscape or portrait
Naming convention for files (using underscore): First_lastname_ number_title_size_in_inches.jpg, for example: Ann_Howard_2_Enchantment_18x24.jpg
An artist statement indicating what you aim to achieve in your artistic work
If existing, a link to animations on which your stills, directly or indirectly, are based.
