Ever since I was in high school, I've always admired a type of hyperrealistic art which was often seen on album cover designs in the late seventies, and which often involved the use of an airbrush (although that wasn't always the case).
One illustrator who is particularly good at that style of art is Jerry LoFaro. Another similarly talented artist is Frank Ordaz. The two artists aren't identical in style. Jerry's images are sometimes less realistic in terms of subject matter. Frank's images are influenced by his Christianity, and by his previous employment with Industrial Light and Magic (where he worked on films such as ET).
Both artists are extremely talented. To be candid, I admire their artistic styles and skills a lot more than some self-proclaimed "fine artists". If I had to choose a style of art I'd love to be able to create myself, I suppose that this style would come closest to my own aspirations.
Interestingly, LoFaro now creates his art mostly with Photoshop (and possibly other digital software programs). The same could also be said for the vast majority of illustrators currently specializing in fantasy and science fiction imagery. It shows how far digital art has come in the past few years.
