So back in the late 80s and possibly into the 90s, I remember seeing ads from Newtek like this on the back of many Amiga mags:
So my question to anyone with knowledge on this subject: how does one convert images into Dynamic HiRes? Is it even possible? I assume that if you had the Digi-View bundle you could save out as DHR, and Newtek released a stand-alone viewer called Dynashow that could display these images. However the only images that I’ve found so far are the ones Newtek created themselves. AFAIK none of the regular paint programs like DPaint supported this mode. Perhaps ADPro did?
I suppose my interest in all of this is purely just for fun of it - seeing how far that original 1985 chipset can be pushed. Eventually I would love to take some true colour 24 bit artwork and see how nice I can get it looking on original Amiga hardware using this mode.
In the meantime, I will continue my research and report back any findings!
I always found those images super impressive and was intrigued by this so-called Dynamic HiRes display mode. It’s only recently that I discovered how it’s actually achieved - essentially it utilises the copper to swap to a new 16 colour palette on every raster line. Of course many games BITD took advantage of similar tricks like this to display over 100 colours on the screen at once. Dynamic HiRes took it even further and offered thousands of on-screen colours in up to 768 x 480 hi-res overscan without the fringing artefacts of HAM mode - and this was all possible on an OCS Amiga! Admittedly it needed the whole system to itself to render the screen in this mode.
