I usually sharpen prior to the resizing and then resize if I need to put them up on the web....using bicubic. I have only recently read that smoother is for for up and sharper is if you are going down.
My question then, if I sharpen the image prior to sizing just as part of my normal workflow, then decide later to resize cause I want to put it up on the web or some other use....should I sharpen again?
OR, should I not sharpen in the first place until I decide what to use the image for and sharpen only after resizing?
Have I confused you yet?
Interesting question. I don't think there really is a right/wrong answer for this. I guess it depends on how much you are sharpening the image, each time you do so
Some people say a
very minor sharpen when first opening the image is a good thing to do, and then a final sharpen again at the very end of your process. Some say you don't need to do the minor sharpen at the start.
If you stand back and think about it, pretty much everything you do when PP'ing your image is potentially degrading the quality, so sharpening the image twice could be seen as "more" destructive than only doing it once at the end. On the other hand, what percentage of degredation are we really talking about ? I don't imagine doing a minor sharpen at the start would cause much concern (IMO). The image straight off the sensor is somewhat soft, due to CCD characteristics (I think), so the minor sharpen at the start is, "supposedly", to lift the image that little bit, prior to beginning your PP work.
As for when to do the final sharpen, if you are saving a
PSD or TIFF of your NEF image, or the NEF image itself (with PP), I would PP up to the point of sharpening, then save and leave it. If you then decide to print a 16x20" or convert to 800x600 for the web, you can then use the appropriate amount of sharpening once you re-open the file (and make a copy).
I possibly do things backwards, however I usually take a copy of the NEF first up, then resize (always using bicubic), for the intended use, then do my PP work. I find that some things are best done when the image is viewed at 100%....however if you haven't resized yet, you're not looking at the real 100%. If, at a later date I decide to do another version of the same image (at a different size), I will again copy the NEF, resize accordingly and do my PP work again, which may be similar or different to the first version of the image, depending on what I'm wanting to do with it on this occassion (and also what suits the size of the image - either large print or web-sized).
I'm sure there are others that can explain their techniques and methodology (possibly better than I have done), but hopefully this gives you some ideas....
