Old HAM pictures from Digiview I think

[Rowbeartoe]

Hey everyone, I have the newtek demo reels but I was wondering if anyone can help me find all those other digiview pictures?  Most notable the butcher series?  Girl with pencil in mouth with green glove and blue background or the girl with a sucker.  Another notable picture was the horse with a taxi in the background.  Digi everything used to have so many great pictures.

Thanks.

That's too bad.  I have photonpaint, but no digi programs.  Well if anyone has those pictures!?!?!  I'd love to have them.  Thanks.  =)

Ok, so now i'm certain these pictures came with Digipaint.  So does anyone have the pictures that came with the program/s.  

Thanks.  

The link below shows the really bad Spectrum 512 conversions of the pictures I'm trying to get.   =)

Ok they didnt' come with Digipaint/s or the NewTek Demo reels. My best guess is they were part of the first Digiview.  My link above shows the pictures in particular I'm looking for that were converted badly to Spectrum 512.  Thanks for anyone who can help.

I use GBMREF on the PC to convert to Amiga Formats.  XNVIEW displays my Amiga pictures that I can then save to BMP or whatever.   I still have to play with my Amiga 500 to file share with the PC (via null modem) so I can start converting SHAM pictures and saving them to the PC using GBMREF.  I have to learn how to do that, and I think I found some places that explains how- but right now I just don't have that kind of time.  My interest right now is in finding those old pictures.  I want to convert them to the Atari ST using Photochrome and other various programs including Spectrum 512 (hopefully with better results).  To bad I couldn't get the orginal photographs in 24bit from those NewTek guys.  =(

Thanks for all your help guys.

Spectrum 512 works so differn't from HAM6 or anything I'm aware- contary to popular belief when converting 24-bit pictures, Spectrum 512 can best (but not always) what can be achieved with HAM6.  Of course converting a HAM6 to Spectrum 512 will always look less impressive because the source is the HAM6 picture. Spectrum 512 divides each scan line 3 times for 48 colors per scan line(actually 42 if you want to use and edit with the paint program, 45 if you don't use the paint program and 48 if you use one of the photochrome modes).  HAM6 can best Spectrum 512 in some ways because you can have 320 colors on a scan line.  But HAM6 is limited because after those 16 "free" colors you can only modifify one of the 3 RGB values from a previous color causing unessary colors. Spectrum 512 is limited to 320x200.  No interlacing.  Photochrome looks amazing (bests VGA in many ways) but wasn't available until early 90's (spectrum 512 came out in 1987!).  Photochrome interlaces two pictures and color mixes giving you 96 colors per scan line and a 4,096 color palette (for standard ST).  Flicker is at a minimum for most cases and is similar to looking at interlaced pictures on the Amiga.  

BTW XNVIEW 1.61 displays Amiga HAM pictures and Spectrum 512.  I think the newest version does not.  

For more details how these ST picture formats work check out the link.  Other paint programs allowed the borders to be removed (neochrome master) as is so common with the Amiga.

Well with my LONG LONG LONG search for these DAM NewTek digiview pictures I can't seem to find, I found this cool PC program. You can use your PC to view Amiga ADF files, then all you have to do is right click and copy to your PC or disk. =) Then use something like XNVIEW (older 1.61) to check out the Amiga HAM pictures. I've been browsing ADF files now all over the net in search for these pictures! Perhaps this will help others who want to help me with this search!?!?

I checked out both New Tek Demo Reels
I checked out Digipaint 1 and 2
I checked out Digiview 4

I think they came out in late 1986 but no later than the end of 1987. (Again, the pictures I'm looking for are in Spectrum 512 format linked above)

Help me find these pictures PLEASE!

Thanks.

haha- yep I forgot to say what the program was- yes ADFVIEW.  It's a lot faster to browse using the PC then converting everything to the Amiga to look.  But the search continues.  Somebody has to have these pictures? I'm guessing they came with Digiview 1.0?  Or it's also likely a store demo or two?

Thanks.

"I was talking about just 32-color mode on amiga not HAM6.  In 32-color mode with a custom copper list, I was able to do 61 free colors per scan line.  Using a 7.16Mhz Amiga, there's enough time in the HBI to modify 14 color registers, and 30 registers during visible portion of screen (in 320*x mode).  Now if you partition the 32 colors into 14:17:1 where the first partition is colors that change during HBI, 17 that are staying the same from scanline i to i+1 (using delta-modulation where more common colors take on those indices), and take the 32nd color and repeatedly change it 30 times during visible portion of the screen you get: 14+17+30 = 61 free colors per scan line more than Spectrum 512.  And I have not involved the Amiga CPU either."

Hey that sounds like a possible Spectrum 512 emulator on the original Amiga?  That would be impressive and makes me wonder why it was never done espcially since this kind of format could (probably more times than not) produce better pictures than HAM6

>Photochrome looks amazing (bests VGA in many ways) but wasn't available until early 90's (spectrum 512 came out in 1987!). Photochrome interlaces two pictures and color mixes giving you 96 colors per scan line and a 4,096 color palette (for standard ST). Flicker is at a minimum for most cases and is similar to looking at interlaced pictures on the Amiga.

Those interlaced colors have to be distinguished from the REAL colors as the interlaced colors have half the refresh rate.

The Atari ST Photochrome interlaces two screens for 96 colors per scan line for a 1985 standard ST computer.  The color changing between the screens just gives the apperance of more than the standard 512 colors.  The results are trully impressive.  I was talking to an ST guy who said he could get the ST Blitter chip to divide the screen pallete one more time making 64 colors a scan line or 128 for photochrome.  Of course the ST Blitter wasn't introduced until 1987 and nobody has ever made the program.  

Still your idea sounds like a great idea to emulate Spectrum 512 on the Amiga.  Something I never thought the original Amiga could do.  =)
