Poor quality images after resizing with photoshop

Hi there,

Up until now I've generally used the Canon Raw software which came with my 50D for processing images. My workflow was very simple. I upped the shaprness to between 5 and 7 (out of 10) then saved as a resized JPEG in order to place the images on my site.

I then used photoshop to apply a watermark to the images and make any colour adjustments to the photo.

I've since started to use the camera raw plugin for photoshop as this has some nice recovery features etc which Canon's software doesn't have. However, when I open the image in photoshop and resize it I get results when simply don't compare well to what the Canon software can produce - and that's without pixel picking. To be honest I'd go as far as saying that photoshop produces blurred images.

No amount of messing about with the unsharpen mask in photoshop seems to help.

Is there something which I'm missing or should I simply stick to the Canon software.

Thanks,

Rich
 
Hard to say What PS have you got I use CS4 open RAW into a TIFF do all work resize as last thing when resizing you can pick the resize with sharpen in the drop down box.
The ARC do not do sharpen only use it on screen and sharpen as last thing.
 
First of all I suspect the Canon software is adding some sharpness by default, it's possibly reading the embeded picture style (one reason why they may look better out of the box) Secondly when you open the image from camera raw there are several option (usually at the bottom giving various sizes options what are yours set to?
 
Thanks,

I'm using CS3 and I can't seem to find these options. I'll keep looking.
 
At the bottom of the camera raw scren is blue lettering, click on that for the options of size etc.
 
Sharpening is a HUGE subject and one which cannnot be covered in a single post however when done correctly adds well to the viewer's pleasure of an image.

As a rule try not to sharpen when processing and save this as a last step before outputting the image (for screen or print) as your requireemnts will vary.

I do not like sharpening on re-size as this is often too aggressive and difficult to control so keep these elements seperate (what I mean is resize using the smoother option and sharpen afterwards).

I often us USM as a way to improve local contrast (usual about 10-20,100+,0) which often sharpens an image well.

When outputting to screen a light smart sharpen using a small pixel radius can really boost an image without artefacts.

Loads of stuff online about sharpening and some tutorials are well worth the time.
