Anyone got any tips for uploading in better quality?
The end result always, ultimately, depends on the
QUALITY of the image you start with. For example, I just checked our
@Paul Lintag's last entry (a
spectacular one, btw!
), and was amazed that the first one is 4962 × 6332 pixels and 1.7 MB because the tFS upload rules
clearly state:
Upload a File (
Max 1 MB )
Max image width: 4,000 pixels
Max image height: 4,000 pixels
So, to answer your question (although it is extremely subjective, because due to the nature of what I do for living, I work on an iMac 2019 (Retina 5K, 27-inch, 5120 x 2880 pixels resolution with support for one billion colours), where every (even the smallest possible one!) imperfection is noticeable), I think that you should not have to go above 1500 pixels width, which brings us back to my initial sentence - if you start with an UHQ image of 6000 pixels width, you can always reduce it to 1500 pixels width and you will have crystal clear image as end result; on the other side, if you start with a photo of 600 pixels width and enlarge it to 1500 pixels width (even using Photoshop's upscaling algorithm known as Preserve Details 2.0), your larger version will inevitably end up looking soft and blurry or chunky and oversharpened.
And last but not least, try to save it as JPEG (maximum quality, never below 10, with possible embedded colour profile sRGB IEC61966-2.1) instead of PNG whose image size is significantly larger than other image file types.
