I have decided on a portfolio item image size of 609 x 406 px. I have found that there is quite a noticeable degradation in image quality when WP makes its thumbnail downsizing, so I thought that if i upload the image in 609 x 406 px I will not have the degradation. (The plan is to also upload a bigger size that will be opened in lightbox.)
The problem for me now is, that even if I upload the exact size that is needed for the portfolio (609×406) the image is still being transformed into an image of the same size, but of worse quality.
If you go to http://www.thevelvetroom.dk/portfolio-item/franny-test2/ the difference should be ease to see. The image you see in the portfolio is 609×406 and has been degraded by WP. When you click on it, the lightbox opens and you will see the original, that is also 609×406. The original is noticeably sharper, and has a slightly better dynamic range.
So my question is: How can I force the portfolio item to use the original 609×406 file and NOT the 609×406 thumbnail?

After a bit of research, I found a tip: Set the thumbnail quality to 100 in /wp-admin/includes/image.php . This actually helped a bit, so now the difference between the portfolio image and the original image (of the the size) is not so big.
I would still love to be able to use the non-thumb image though. As a photographer it seems a bit silly not to use the best quality you can.July 15, 2012 at 11:05 pm #83078

Thanks Ismael. As I wrote, I already set thumb qulity to 100. It did get better, but I want the best :-)
So my question is still: How can I force the portfolio item to use my original 609×406 file and NOT the 609×406 thumbnail?July 16, 2012 at 8:55 am #83080
More research: I made a test where I uploaded my own (sharp) 609×406 thumbnail. It turns out, that even if the 609×406 thumb is sharp, when it is shown in the portfolio (in the 609×406 “window”) it somehow gets degraded (fuzzy).
So now my above question is *not* the one to answer. :-(
So far the only way to see a sharp non-degraded image, seems to be in the lightbox. Bummer.July 17, 2012 at 7:45 pm #83081
