While crop for effect (as mentioned last month) is usually a little more expensive at most publishing houses, we perform this service to some extent, free of charge and the end result is much more gratifying. Our professionals will choose exactly where the half-tone should be cropped and/or enlarged/reduced at no additional charge to you.  After all, are you trying to show Uncle Ed or the yard he was standing in? Of course, there are times when the background IS the picture. We also receive instructions to enlarge or reduce to a specified size without cropping and it is physically impossible to comply, because without cropping, the size specified cannot be reached from the original without warping the outcome. Enlargement or reduction can only be done overall, not in only one direction. When we face such a problem, we use the largest dimension, and let the smaller fall where it may. [If 3″x5″ is specified, when we get to the 5″ measurement, the requested 3″ may be less than 3″.] If an author prefers total control over their sizing and cropping, this can also be done with us at an additional charge in-house or they can send exactly what they want and mark “same size originals” at no additional cost.
