[Alt-photo] Re: lith printing anomaly

[Christina Anderson]

Hi Kevin,
No, enlarger printed for the most part, although last year I started introducing the BW digineg in this Experimental Photography class just in case we have to end up going there permanently with the way of the world. Some students are thrilled and go straight digital with their work, maybe 5 of the 18. Other students think I have defected from analog as they are film all the way. Plus the class is based on Holga and pinhole work (although you can buy a Holga lens for a digital SLR too...).
