In some cases, there may also have been more than one set of blocks made, or replaced over time. There are for example significant variations in the exact patterns in the waves seen in different examples of this print in galleries around the world. Furthermore, there have been at least 4 stages of digital image processing involved in producing my image: the original photograph, post-processing before posting on the Web, pre-processing and cropping in preparation for Rasta and finally the Rasta conversion itself. Something like this ? It's not a perfect conversion yet, I'm still working on it... VERY NICE !!! Gamma is a bit off (e.g. mid-tones set towards the bright-side of the scale... I would dial them a bit lower, make it look creamier...) But nonetheless., surprised how WELL it gets reproduced on Atari's spatial + color capabilities...

drpeter Posted October 20, 2019 Share Posted October 20, 2019 OK, back on topic.... Detail from Ophelia Ophelia (1852) is a painting in the Pre-Raphaelite style by British artist Sir John Everett Millais. Held in the collection of Tate Britain in London it depicts Ophelia, a character from William Shakespeare's play Hamlet. The model in the painting is Dante Gabriel Rosseti's muse and future wife the 21-year-old Elizabeth Siddal, later an important artist and poet in her own right, who posed daily over the course of many months floating fully clothed in a bathtub of water kept heated by oil lamps. --------------------------------------------------------------------------------------------------------------------------------------------------- Mad with grief for her father Polonius- murdered by the hand of Hamlet- the wandering Ophelia falls accidentally into a river where, apparently incapable of acting to save herself, she sings distractedly until dragged beneath the waters. Hamlet Act 4 Scene 7 QUEEN GERTRUDE One woe doth tread upon another’s heel, So fast they follow.—Your sister’s drowned, Laertes. LAERTES Drowned? Oh, where? QUEEN GERTRUDE There is a willow grows aslant a brook That shows his hoar leaves in the glassy stream. There with fantastic garlands did she come Of crowflowers, nettles, daisies, and long purples, That liberal shepherds give a grosser name, But our cold maids do “dead men’s fingers” call them. There, on the pendant boughs her coronet weeds Clambering to hang, an envious sliver broke, When down her weedy trophies and herself Fell in the weeping brook. Her clothes spread wide, And mermaid-like a while they bore her up, Which time she chanted snatches of old lauds As one incapable of her own distress, Or like a creature native and indued Unto that element. But long it could not be Till that her garments, heavy with their drink, Pulled the poor wretch from her melodious lay To muddy death. drpeter_Ophelia.xex 12 Quote Link to comment Share on other sites More sharing options...

drpeter Posted October 22, 2019 Share Posted October 22, 2019 Summer Moon Seen from Itsukushima Shrine Woodblock print, Tsuchiya Koitsu 1936 Itsukushima, commonly known as Miyajima, is a historic sacred island set in the Seto inland sea off the coast of Hiroshima, Japan. It is best known for its 'floating' vermilion Shinto torii gate, which is surrounded by the sea at high tide and a UNESCO World Heritage Site, but there are numerous other shrines and attractions scattered across the island which is a popular tourist attraction. This view of the moonlit shrine predates the nocturnal illumination that now keeps the torii gate brightly visible day and night. The striking violet tint in the clouds is sometimes seen in brightly moonlit coastal scenes and is not (necessarily) artistic license! 86 colours drpeter_Miyajima.xex 10 Quote Link to comment Share on other sites More sharing options...

I understood the last posts that there were new issues discovered in Altirra and pictures displayed there were different from real Atari. RastaConverter to have the problem fixed would require serious refactoring and neither me nor Phaeron has time for this. Even simpler approach of identification problematic cases would be quite time consuming. I must thank you for creating such a great tool in the form of RastaConverter. As you've noticed, it's become something of a fun obsession for me! I'm curious- how do the rendered images avoid showing stripes in the borders as COLBAK changes? These stripes appear when the image is converted to a Graph2Font file... With best wishes (and again, many thanks) Peter Quote Link to comment Share on other sites More sharing options...

drpeter Posted October 31, 2019 Share Posted October 31, 2019 Severinus The Herbalist Another film suggestion for a spooky Halloween- the 1986 Jean-Jacques Annaud screen adaptation (or palimpsest, as suggested in the titles) of Umberto Eco's famously erudite creepy mediaeval murder mystery novel, The Name of the Rose. In this scene Severinus (Elya Baskin), the herbalist, is in conversation (over a corpse) with William of Baskerville (Sean Connery), a visiting Franciscan monk, and is obliquely hinting at some of the secret goings-on at the isolated Italian monastery where a series of macabre and inexplicable murders is taking place: 37 colours -------------------------------------------------------------------------------------------------------------------------------------------------------------- William: Was he on friendly terms with the handsome young Adelmo? Severinus: Yes. They worked together in the scriptorium. But in a brotherly way, you understand? Not like... I mean, flesh can be tempted according to nature... or against nature. And they were not of the latter disposition. If you ascertain my meaning. drpeter_Severinus.xex 5 Quote Link to comment Share on other sites More sharing options...

a8isa1 Posted October 31, 2019 Share Posted October 31, 2019 I've reverted back to Altirra's default NTSC XL palette for processing. If using emulators to view please use more saturation. (Saturation 50 in Altirra). [NTSC - 45 colors] [PAL - 43 colors] Please try to ignore the vertical rock (foreground, left). I never managed to get that area to resolve. I guess now that I've mentioned the problem areas they will be impossible to ignore. I find it interesting that my PAL conversions only require 25% (or less) the amount of processing time that the NTSC ones do. -SteveS a8isa1_maine_coast.xex a8isa1_maine_coast_PAL.xex 9 Quote Link to comment Share on other sites More sharing options...

I did the former when I was doing NTSC, before my last attempts, and when I finally saw them on a real NTSC machine, dark green over black areas was rampant, that wasn't an issue with the PAL versions. as .png's they looked great. As it turned out, I couldn't fix the green streaking issue even when I attempted NTSC images from the start and adjusted Rastaconverter for the palette. I don't know if I ever tried the Altirra XL palette, There weren't any NTSC palette's that came with the Rastaconverter zip I downloaded, I just added in ones people posted in the thread or sig like you.

I was using custom NTSC palettes (see my sig). These worked quite well with an old TV which I no longer have. Now I'm using Altirra's palettes but with a variety of saturation levels. This does not change the colors that the Atari can display but a different saturation level in a palette subtly changes the choices Rastaconverter makes during processing. I've been working with this photo off and on for 3-4 days. I actually forgot to run the latest NTSC XEX on the real Atari. Setting that up now... My remaining monitor choices are pretty poor, a dying CRT and horrible LCD, both VGA, on a scan converter which doesn't appear to be properly calibrated. It's really a consumer 'set top box' but for computers. Made around 1999. I think the colors of the NTSC conversion are close. I'm seeing a faint violet hue that I believe should be cyan-ish (sky color), in or next to the clouds. The other colors seem to line up properly between the rastaconverter GUI, emulators and my 800XL. I don't have any PAL gear at all. -SteveS 1 Quote Link to comment Share on other sites More sharing options...

Sorry, I didn't answer your question earlier. Same exact settings for both the NTSC and PAL conversions. I'm seeing now that the NTSC one should have had less contrast. Parts of the clouds have 'whited out'. The PAL conversion needed more brightness. The line dither (/dither_val=0.3, /dither_rand=1.0) wasn't hidden as well as with the NTSC conversion. (I now see the dither pattern all over the water). -SteveS Quote Link to comment Share on other sites More sharing options...

drpeter Posted November 3, 2019 Share Posted November 3, 2019 The Fighting Temeraire 55 colours The Fighting Temeraire, tugged to her last berth to be broken up, 1838 (National Gallery, London, UK) One of the later works of English Romantic artist Joseph Mallord William Turner, this painting in oil was one of his own favourites. He refused to sell it in his lifetime and on his death in 1851 it was bequeathed to the nation. It is also a national favourite- in 2005 voted the most loved painting held in any UK collection in a BBC poll. Turner's unconventional approach to form and colour, studied among others by Claude Monet during the latter's sojourn in London, led to his being described as father of the later Impressionist movement. The painting depicts the ignominious final passage of 98-gun ship-of-the-line HMS Temeraire, long renowned for her valiant exploits in the Battle of Trafalgar 33 years before. Floating almost ghost-like, the venerable warship is towed slowly behind a squat, black steam tug, the smoke from whose fiery smokestack partially obscures the old vessel before merging into mist and cloud. Behind, the light of a dramatic sunset explodes into a turbulent sky and spills blood-like across the murky waters of the Thames. Many have interpreted the ethereal Marie-Celeste-like appearance of the Temeraire, contrasted with the dark and ugly agent of her demise, as wistful pictorial commentary on the passing of the gallant age of sail, or more generally of a romantically nostalgic view of an England now past- a symbolism evocatively emphasised by the violently setting sun. This romantic theme was to find echoes 70 years later in John Masefield's famous sea-poem 'Cargoes'. drpeter_Temeraire.xex 6 Quote Link to comment Share on other sites More sharing options...
