As a certifiable Ludite, ( i still believe in the human soul)

i have been trying to upload pics on this site, but usually have probs, (it would be good to have an auto feature on an image based website!)

but, short of buying a program, like aperture, which i will do eventually, is any one using any good freebies.

i just tried to down load a couple but none seemed to work.


reminding me why i love being a ludite, and hate being caught in the maelstrom of stupid computers.

cheers

There is a very popular free program called GIMP (http://www.gimp.org) - and there are plenty of free GIMP tutorials on the web too.

If you're on a Mac you can use Preview which is part of OS X

The Phocus program from Hasselblad will do most image manipulations that the high-priced programs will do...

and it's free. Download from www.hasselbladusa.com

You need to register at the site, but that's free, and you get email notices of updates (also free).

Excellent program, and works with all standard file formats. The Mac version works with proprietary raw formats from most manufacturers.

Step 1: Go into Preview, and choose "Adjust Size..." from the Tools menu.

Yes, Preview is a good quick and dirty way to resize and do basic tonal adjustments. Resize first, then sharpen then save as jpg.

i really dont know why billion doller iphoto does not do it.

The web and photo's have been synonymous for years, decades even, but like me and digital, we will catch up, eventually.

I don't know if this works on Mac, but it is incredibly simple on my Gateway.

iPhoto will do it when you use "Export".

Not quite free: K Studio Resize (http://kstudio.net/re.html)
I use it to get collections of jpegs to the same size for my web portfolio (http://www.christopherbroadbent.pro/).

One thing to keep in mind is that there is lots of software that does not resize images correctly. The problem is that they are not gamma-aware so they alter the brightness of the image by incorrectly assuming that output R/G/B intensities are a linear function of the R/G/B values of an image. When taking the average of a R255 G255 B255 pixel and a R0 G0 B0 pixel in a non-linear color space (including sRGB, AdobeRGB etc.), R127 G127 B127 would not be correct. You can read about the issue here:

I have no idea if iPhoto is correct, but I'd assume it is since the OSX image processing library is.

iPhoto and Preview do it correctly. The entire Quartz imaging pipeline is based on linear values.

However, I'm sure it's bilinear interpolation, which is not "ideal" for either reductions or enlargements. But it is GPU accelerated, and if you're really that picky you should own Photoshop anyway.

I always used iphoto and it did a great job.
