I am working on 2 presentations one of them is working great the other has really blurry pictures and the text is all really blurry, they both have a lot of the same content as the other one and I don't know what to do about this, I have double checked when I published the quality is set to high... What do I do about the blurry photos and text?
Most of the time when I see blurry images that cannot be improved by the quality settings, it is because the images were large, high resolution images that were inserted and scaled down significantly. This leads to high image compression, and a blurry look. Use and application like Photoshop to re-scale the image down to a more appropriate size and then re-insert the image and see if that helps.
For the blurry text, it could just be a font that isn't supported, so you may want to try changing your font, or save as a PPT instead of a PPTX and see if that helps.
