Sharpening, I shoot raw and have been doing any sharpening before resizing the image:bonk::bonk::bonk:

Maybe I should have kept this to myself
:$
 
Ideally it needs to be done twice, before and after the re-size. Before to combat the AA filter in camera and after to combat the averaging from the re-size. But I use LR and that does all the hard work for me :thumbs:

Do you select sharpen when exporting or does it sharpen automatically when you're exporting?

Or am i completely off...
 
I was told (on here i think) that you shouldnt sharpen a re-sized image :shrug:

I have ran a few through and seen a noticeable difference sharpening after resizing , so to sharpen before and after I expect you have to be careful not oversharpen.

I always re sharpened any photos for the web. :rules:

I only sharpen during export from Lightroom. Don't know why, but sharpening before export never seems to make much difference as far as I can see.
 
I never sharpen. Ever. Am I a twit?

LR adds some "input" sharpening by default and it does make a difference in recovering fine detail pinched by the AA filter.

Honestly, I leave LR on the defaults, just selecting the right type of output medium when I export. For web based stuff I think it's about right on standard and for prints as long as you export to match the print size and PPI/DPI of the printer then it's just lovely. If you export full size and then print smaller at some point it's being scaled by s/w and it kills the detail :(
 
So now I am thinking there is room for even more improvement:)

Just found this excellent post, which offers the same advice said here.

(PP is not my strongpoint:))

It's also worth noting that many camera sensors have a filter in front of the sensor itself, called an "anti aliasing filter". It basically blurs the image projected by the lens onto the sensor - a bit batty if you ask me - but essential in order to avoid or reduce moire patterns with certain types of subject/background.

When you shoot to JPEG the camera's own internal processing will usually sharpen the image data before it saves it to a file (unless you disable in camera sharpening). When you shoot to raw there is no sharpening performed in the camera, so no matter how sharp your lens, or accurate your focus, or steady your aim, or high your shutter speed, the image will be soft. Thus when you shoot to raw you should fully expect to sharpen your images before finalising the image for print or other display. Some raw processors will start out with some default sharpening, such as Lightroom, while others may not. when you shoot raw you get to choose how much to sharpen, and how exactly to sharpen, in your raw software. You don't have to be constrained by what the camera spits out when it saves to JPEG.

Furthermore, when you resize an image to make it smaller, all those fine edge details get splatted together and any sharpening you might have performed earlier in your workflow (including sharpening by the camera if you shoot to JPEG) pretty much gets thrown out with the bathwater. Thus your very last step, after all your edits, resizing etc. is to (re)sharpen the final image before it is ready for display. Some software might do this for you while some may not. In Lightroom 2, for example, there is an option when you finally export/save an edited file to sharpen it one last time as it is resized and saved/exported.

p.s. some people actually have their cameras modified to have the AA filter removed. See this page, which does explain and demonstrate the effect of AA filter removal - http://www.maxmax.com/hot_rod_visible.htm

p.p.s Some people actually have three sharpening stages in their workflow....

1. "capture sharpening" to basically counter the effect of the AA filter; if using Photoshop you might do this in ACR first, before opening the file in Photoshop for artistic editing.
2. "creative sharpening" to enhance the image as necessary to make it pop etc.;
3. "output sharpening" which is the final sharpening step after resizing and before saving/printing. (sharpening for print should be more aggressive than sharpening for screen display)

Aaaaaaand go! ;)

Photoshop/lightroom/aperture/GIMP...etc...sharpening modules will be somewhat more advanced than the one built into your camera firmwire :)
 
Get a copy of real world sharpening by Bruce Fraiser, you'll find it an interesting read.
He suggests a 2 or 3 step sharpening workflow.
1 capture sharpening (to restore sharpness lost to the AA filter)
2 creative sharpening (maybe just the eyes in a portrait or whatever)
3 output sharpening, this varies a lot due to size and whether it's for web or print and even what paper your using (gloss matt etc)
 
it was several months before i realised you had to sharpen images ! i was shooting in RAW as well !! what a difference it made , Doh !
 
When resizing to much smaller sizes (like for the Web of 10 years ago) you should soften first, perhaps in stages before downsizing by 50% each step. Finish up with an unsharpen or two, for different levels of detail.

This helps with reducing the moiré pattern in photos of tiled roofs etc. and the jaggedness of diagonals. As the overall detail is reduced the JPEG file sizes are smaller, which used to matter.
 
Strewth..what a plumb i have been! I have just looked at the export options and have noticed that everything i need is there plus i have just turned on the auto sharpen on export...WOW! This will save SO much mucking about.

THANK YOU!!!!
 
I was under the impression that any Picture Style setting is embedded in the RAW file itself. For example image 1 was taken with sharpening in camera set to 0. Image two was taken with in camera sharpening set to 7, notice the position of the sharpen slider :D

Yes, but you've opened in Canon's s/w which does read the picture style settings, no other apps does.

Ok thanks for that. Now I might be confusing myself here completely so put me straight if I am :) what is the point of using or adjusting picture style settings if shooting RAW, if the apps you use for editing does not carry that info across. No matter what you have it set on, in theory if you took the same shot using a dozen different in camera styles and settings, each picture would look identical yeh? :shrug::shrug:
 
Yes, picture styles are a canon only thing so unless you stick with their s/w or shoot jpeg it is a waste of time.
 
I only sharpen after re-sizing if I feel it needs it. I think in my latest set of photos I sharpened maybe one or 2.

I reduce the quality quite substantially and so that pretty much ruins any sharpening I do. At least I think it does.
