resize image with minimal quality loss?

Hey,

I was wondering is there any other way than using photoshop to resize images with minimal quality loss. Im asking because the quality that the photoshop resizing gives for me doesn't satisfy me at all and after making pictures 800x533 it looks like s*** or am I doing something wrong?

Sorry, if there was any kind of thread, im just cant find any related to it.

NOTICE: im not asking how to resize images (THE PROCESS) i am asking is there any possibility to resize them with minimal or less quality loss than in photoshop.

Thanks in advance

P.S. im mac user

What image quality issues are you seeing? Are you going from big to smaller or small to bigger? Which re-sampling options are you using (for example, bicubic)? Are you viewing the re-sized image in Photoshop or after you save as a JPEG? If viewing the re-sized image as a JPEG file are you using the highest quality JPEG settings when saving?

With CS5?

Size photos with the following options check-marked in the Image Screen:
a. Constrain Proportions
b. Resample Image: Bicubic (best for smooth gradients)

I'd like to add one question:

How big are you viewing the resized image?

The very definition of downsizing = throwing out info = quality loss.

Are you sharpening after resizing? It's necessary - throwing away 3/4 of your pixels means fuzzy edges that need to be resharpened.

So resharpen after you downsize? Ive never tried this before....

try IRFanView, its free and for webloads specially here, its pretty good

i usually Filter>Sharpen>Sharpen then Edit>Fade Sharpen>60 % to save it looking over sharpened.. YMMV

Yep. Always my final step before saving.

Agree. Try using something like Amount 30%, Radius 1.2 & 0 Threshold. Someone here told me those setting years back and I find them a good starting point for 800x535 web images.

I'd also stay away from "Save for web" and use "Save as" then add a tag to the image name like "web". Brilliant, I know.

Alternative to sharpening (the quick and dirty way): Use Bicubic sharper.

Another option: Use the Manyk SRS action.

You can find that action Here.
There's also an example: One image with these 4 different ways of downsizing

Pictures resized in Thumbs Plus, then sharpened.

Byte size: ZERO | Content warning: NOT AN IMAGE

Not fair! You obviously have a very good cam- lens setup, and perfectly focused shots to start with.
Makes me feel hopeless But thanks for the advice. Are you saying that Thumbs Plus should do a better job than CS4? If so, I may give it a try.
Thanks

I'd say it's more that different approaches may appeal to different people. You can get excellent output from CS4, you just find a technique that works for you. Many people just run a quick sharpening routine on an image after resizing it for the Web. If you are bothered about a lack of detailed sharpness, try that. If it's another aspect of the image quality, such as a lack of a "contrasty look", then another approach can address that.

If you downsize, don't resample. In PS uncheck resample and when you change the size you won't see any change in the onscreen image, but the PPI will increase.
