zen photo image quality - help needed

Hi , My web designer is using Zenphoto for my gallaries. He sent me a link to the gallaries and many of the images

are soft. The images I sent him on a disk were not, could anyone tell me what we are doing wrong? Is it a size or

resolution problem on my end?

All help would be appreaciated

You are downsizing from the full resolution images. When you do that there are a variety of choices of algorithms. Even the best ones produce images that can be a little soft, so you should run some kind of unsharp mask on the downsized images.

For important uses I always explicitly down-sample and sharpen at the final resolution and with the final use (web, halftone, etc.) in mind.

 

It can (often) be done en masse from high-resolution (and wide-gamut) originals using a Photoshop action (or similar) that's tuned to the end-use.

<p>Often these gallery software packages do a poor job of resizing. We usually action the job in PS, and replace the folder full of images on the server</p>

<p>I use Zenphoto for my website pragueinphotos.com and I have to say it works GREAT!!!<br>

There is an easy solution for your problem: In the Zenphoto Administration panel, go to "options," then "image." Under "Image quality," you can set the compression for images (100 best quality, biggest file; 0 worst quality, smallest file). Set this higher, then scroll down to "Sharpen". Normally, unsharp mask is only applied to thumbnails, not images. Check the mark for images and all images will automatically be sharpened. This uses more resources on your web server, of course (Warning: can overload slow servers).<br>

On the same settings screen, you can also apply a watermark etc.<br>

Hope this helps. Please contact me if you have any more questions.<br />Michael</p>
