I have been using the Jeffrey Friedel plug in to up load images to Zenfolio. I've noticed that the images on Zen, in the slideshow mode, are not as sharp as they should be. I played around with numerous export settings, from full size to the recommended 1100 x 850 pixels, and with the output sharpening standard and high in Lr. I also exported some images from Lr to reduced JPGs, which looked good on my computer screen, and then uploaded these to Zen. All of these methods result in rather unsharp screen images when viewed at Zenfolio.
I'm pretty sure Jeffry and Adobe are innocent here. Zen is doing something to the images that causes them to lose their crispness. Does anyone know what Zen is doing and is there a way to upload to Zenfolio so that you get good, crisp on-screen images?
