I have tried a number of different options but none give me the sharp image that other portfolios on the same site have. I have reduced my 80MB TIFF files to jpegs (200-600kb) with a width of 600 pixels and with varying resolutions of 72ppi - 300ppi. I have also sharpened the images using both the smart sharpen and unmask sharpen tools. The files are sharp when opened on my laptop but after uploading always are blurred on the site itself. Does anyone have any experince of this or advice? Thanks.
