when i do the inevitable pp on my shots i do all the adjustments except final sharpening at full image size...then resize and sharpen

is this good or should i size the image then do the adjustments and sharpen

i only do jpegs but any input would be good for me to know

cheers
 
I generally do most if not all PP at full image size - if you need to do any delicate cloning or masking it is much easier when you have plenty of pixels to work with. The only disadvantage is that if you have lots of layers and an old computer it may start to struggle, as the file size can become pretty big.

If you are zooming out to judge the overall effect make sure you are viewing at 50%, 25% or 12 1/2% - other percentages introduce funny artefacts.

thanks
i will stick to full size just now and appreciate your observation
i usually have to down size so leave sharpening to last...does that sound about right?
regarding cloning...i blow the shot up to do that if its local

Usually, one is better off sharpening at the final size. If an image is downsized, for example, it loses apparent sharpness.
 
You absolutely must sharpen the image if you downsize it - you can actually see the loss in resolution. You can't resize an image from a few thousand pixels wide down to 800 - they just don't fit. A similar situation exists if you rotate an image even by as little as 1 degree it will lose resolution and need sharpening. Rotating by 90, 180 or 360 degs will have no effect on resolution, but anything in between those angles will need sharpening.

Soz - long winded way of saying you're doing it right anyway. :thumbs:

I use lightroom for all exporting so screen or web sharpening is applied on resizing or exporting to print whether I have made adjustments or not

Well that's handy I suppose if you're processing a lot of images - I don't use LR so I do my sharpening manually for each image.Tbh though, I find the sharpening needed varies with the image anyway, so I think I'd rather do it that way.

v true, I don't really know enough about how sharpening works tbh
 
Well the amount of sharpening will vary with subject matter sometimes David, and even something as daft as how sharp the original file was.

Digital sharpening basically works by just increasing the contrast between adjoining areas of lighter and darker contrast - it all smacks a bit of smoke and mirrors I suppose.

Have a look at this - scroll down to 'What is Sharpening'
