The move up to medium format in 1974 just increased his desire to move up again in negative size and in 1976 he purchased a used Crown Graphic 4X5 press camera stripped it down and used it as a field camera. He currently uses a Zone VI 4X5 field camera purchased in 1989  but does not get to use it as often as he would like.

 Prior to building his darkroom in 1980; he had been using a commercial lab to process his film but was never completely satisfied with the results.  With the darkroom up and running; Alistair soon realized that he had a lot to learn about  black and white printing. What he needed was information and he got it he says by reading every photographic book he could lay his hands on at  local libraries." Fortunately" he says "some of it stuck".

1984, first image published in Camera Canada Magazine. 1989, Five images of Japan accepted for exhibit in a N.A.P.A. show in Vancouver.  One image placed third and one image received an Honorable Mention in 1991 A.P.A.C. show. 1994,Three images of Boston accepted for exhibit at N.A.P.A. show in New Westminster. Mounted first one man show of twenty three images at the Photographic Gallery at the Gateway Theatre in Richmond. 1998-2000, Five acceptances in International Salons.  Several of his images are in private collections in Canada and the United States.

Alistair's long time involvement in fine art black and white photography prompted him to build his own print washer. Over a number of years the washer was redesigned and in 1998 had evolved into the highly efficient and beautiful CROSS-JET print washer he started marketing the washer in the fall of 2000. At the same point in time he became interested in making unsharp masks but was unable to find any registration systems being made. Alistair did what he has always done if he cant buy what he needs he builds it; his first registration punch and easel  worked so well other photographers wanted it and the Inglis Unsharp masking system was launched. The Unsharp system now includes pinned carriers for most of the more popular brands of enlargers. In 2004 a complete suite of sheet film washers was introduced and have been very well received by large format photographers.

The summer of 2007 saw the introduction of a compact gaseous burst development system for sheet film from 4X5 to 8X20 with larger formats available by request.
