I feel like that if I have lacking in any area of technique in terms of getting a technically perfect image, then I have more things that are out of my control than I am comfortable with.
For example, out of all my LF lenses, only one needs to be seriously corrected for focus shift when using IR film, my Schneider 350mm F/11. I had to go through about $40 worth of film in a roll film back before I knew where that correction was, an unwelcome "leave it to chance" kind of thing.
Once I am 100% on my technical ability, then all the things that I love that are not in my control have a chance to play a much greater role in making an extraordinary image happen versus just a technically perfect one.
That's pretty much how I roll...
