Better picture sharpness in full size than viewed in image gallery

  1. By adding an image gallery to your blog, you allow other viewers to easily browse your pictures. Unfortunately, the sharpness of the pictures when viewed this way, is not as good as when you click the 'View in full size' link in the bottom right of your viewer.
    I have tried uploading pictures with different sizes (long edge=1280pix, 1600pix & 1920pix). I have also tried to change the resolution from 240pix/inch to 72pix/inc. The image format is jpg, and the color space is sRGB.

    Any suggestions how to fix this will be greatly appreciated.

    The blog I need help with is bwephoto.wordpress.com.

  2. Prior to uploading any image into your blog, regardless if it’s a header image, a featured image, an image in a post or page, in a Post format (Gallery or Image), an image for sidebar display in an image widget or a text widget, you can optimize and re-size it in either a desktop image editing software or online image editing software to fit exactly into the space you intend to use it in. By undertaking proper image preparation first you will get the best image quality, won't be wasting your media storage space, and won't be wasting your time troubleshooting.

  3. Thank you for your prompt answer.
    As i mentioned, I have tried to alter the picture size, but that did not change anything. As far as I can see, it does not matter which size i upload.
    I am using the Twenty Eleven theme, but have tried others as well, but it is always the same. Does the Image Gallery require a standard resolution and/or a standard format?

  4. When it comes to the Gallery, I rely on justjennifer's blog and her answers to forum questions.

  5. Thanks again, timethief
    I followed your link to justjennifer's blog. From her page, I followed this link:

    WordPress.com implements the Photo Carousel

    In the example shown here, you have the exact same problem as I am having. It is not so pronounced in the close-ups, but start the Carousel and browse to either the picture of St. Stephens Basilica, or the one of Castle Hill Tunnel. If you then click the 'View full size...' the picture open in a new tab. If you compare the pictures in these two tabs, you see that the full size view is sharper than the one in the Carousel.

    I guess this means I have to except it as it is, or just deactivate the Carousel.

  6. Any image displayed on the Web will be shown at 72ppi. There is no reason to upload images at a higher ppi. This may not be true with the new Retina displays, but unless you have a Macbook Pro, it probably isn't relevant. http://en.blog.wordpress.com/2012/08/02/a-high-resolution-experience/

    As far as image sharpness, it's been an ongoing concern and you can find good information both on tt's website as well as Panos' site

    The Image Carousel changes image size dynamically according to the size of the monitor the Carousel is being viewed on, but I don't believe larger than what you've uploaded. (I don't have access to a large monitor to check this properly.) So if you view your images on a very large monitor rather than my little 15"-er, you may get better clarity. Again, YMMV.

    Deactivating the Image Carousel will most likely not change image clarity if you've uploaded a very large image, because the image is still being resized to fit the width of the posting column of your theme.

  7. Jennifer, no I am not a Mac user. I have been visiting both sites you mentioned, but could not find anything about preferred size for the Photo Carousel, and as you say, the size will be dynamically adjusted to match your browser window, also independent of which zoom level you have chosen.
    When it comes to monitor size and sharpness, I thought smaller is better. When opening the picture in full size view, and then resizing your browser window, the image size will be resized accordingly, BUT sharpness is still better than viewed from the Carousel.
    My thoughts on deactivating the Carousel, were to present icons for viewers to click on and view the full size. Not a good solution, but with better image sharpness.

    I hope that someone can come up with a solution to the sharpness problem, 'cause I really like the Carousel. You should be able to choose the image size yourself.

  8. If you deactivate the Carousel, then just link your Gallery thumbnails to their file (in the Gallery tab of the Image Uploader). That should cover it, although I personally dislike the lack of navigation when linking to files.
