Welcome to the Forum, GR. (Or is it BTM?). Most careful workers do record, or at least can remember in general what equipment they used, lens focal length, and type of film. If any filters were used? Special lighting? Just knowing the exposure alone is usually not too informative, but it is useful knowing if a very fast, or slow, shutter speed, or aperature opening, was used to achieve a particular effect. Also, its nice to know things like, "This was bright snow, so I gave it two stops more exposure..." And, if special processing is used, as with Photoshop filters, it is also instructive to note. I always tell myself I should carry a notebook. But at least I try to remember the general process that went into the photo. Thank you for the suggestion. I'll try to make a point of posting a few mor details.
