Can we get sharper thumbnails?

15 Sep 2009, 16:20

I'd like to have sharper thumbnails. I'm not talking about the rollover image (I disabled that), but the main thumbnails. I'm used to being able to set the thumbnail sharpness in Breezebrowser, and the Imagevue thumbnails are really soft (in my opinion). I'm using Quality = 100%.

hmm, it never occurred to me that the thumbnails don ´t look good, especially if you turn up the quality. We are using a PHP library for resizing, and I would need to check all the functions with my partner to see if there are other options in the resizing except for quality. I know for sure there isnt a specific function for "sharpen", but there are functions for: imageantialias(on/off), imagecopyresampled and imagecopyresized. (Taken from http://th.php.net/manual/en/book.image.php )

I can ´t immediately see that any change in the settings above would help. If you turn of antialias, thumbs will look very pixelated.

This is not Imagevues fault - Take a look at your fullscreen image:

... then take a look at the thumbnail for this image:

It is a direct mirror of your fullsize image!

Your custom image however:

This has gone through some custom process of contrast or saturation or whitening. That is not any default SHARPENING! As you can see compared to your original image, the original has much more grey in the background, and this will not disappear merely with sharpening the image. Why not fix your original images first?

Thanks, Karl, I had completely forgotten that those two sets of photos were from different RAW conversions of those images (and different processing afterward; done years apart). I'll do them both from the same images later.

You're right. There may be a bit of difference between these sets, but not very much. I'd say Imageview is doing a good job with thumbnails.
