Maximus, dont take this the wrong way, as I value what you are saying. I am not saying that the image should be so good and strong, as to not warrant expert printing, as this should obviously be the next logical step. However, the time spent printing is not a reflection of image value. The time involved in making the print is of no significance to the value of the final print, if it be 10 seconds or several hours.
Of course, Clive, maybe my words came across the wrong way. The "real" value is not in the time itself (although, from a business standpoint time is money). I used 3 hours, but it could be two minutes, or whatever it takes to achieve a great print and one that the artist (and potential buyers/viewers) can be satisfied with. Now, from a "perceived" value standpoint, this could be looked at differently. Let's say I have a very difficult negative, of a great image, that I really want to bring out in print. Such negative may require extended time and a few somersaults in the darkroom. That final print may have more emotional value to me because it required extra time and effort, and a great result giving a higher sense of accomplishment. Now, if I can transfer that same notion of value to a viewer (or again, maybe a potential buyer), I have achieved my goals, an even greater sense of satisfaction, and "real" tangible value.
