Hi there,

I am finding that the output images are still pretty blurry. I have attached the before and afters below: -

Am i doing something wrong? My script is as follows:

#!/bin/bash

cd input
list=$(ls *.JPG)
for img in $list; do
inname=$(convert -ping $img -format "%t" info:)
convert $img -strip -colorspace sRGB -resize 700x466! -interlace JPEG -sampling-factor 4:2:0 -quality 80 ../output-run2/${inname}.jpg
done

echo Success: Optimised images in /output-run2

Any help on this would be great

thanks

Images for the web are commonly sharpened. See http://www.imagemagick.org/script/comma ... ptions.php , the "-sharpen" and "-unsharp" options.

When an image is downsized for the web, I like the method shown in Resampling with halo minimization
