<body><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">As the conversation continued here in private, the explanation.</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">Sony RAW files can have a fairly small embedded preview.</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">Here 1920x1080 to 6024x4024, plus a different aspect ratio of 16:9 to 3:2.</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">Since we scale the preview to the same optical size, there is a strong loss of sharpness.</p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">We added the ability to preview the full RAW image in digiKam-8.0.0, high quality but slower.</p>
