These paintings differ materially from the common lantern slides, requiring first-rate artistic talent 

 to make them effective, as, owing to the intensity of the light, the slightest defect is developed. They 

 therefore require the most scrupulous care with regard to the minutest details. Subjects may be 

 painted to suit the taste or view of the purchaser, varying in price according to the subject and size of 

 the painting. 



Slides carefully painted from Drawings or Photographs to order. 

 Engravings, Drawings, Maps, &c., copied by Photography for the Magic Lantern, &c.
