	Well, that's what gamma correction is for.  But banding shows
up in my renderings even at very high intesities.

	I think I disagree with this.  What if I need more than 256
shades of some hue?  What if the precision of our rendering software
is much, much higher than 8-bits and we need that precision?

A few months ago, there were a slew of messages from people desperately
looking for a font editor.  I've never used AmigaOS 1.3, but recently
someone mentioned that there was a font editor in the Tools directory
of the 1.3 Extras disk.  I checked mine, and sure enough, there was
Fed.  I ran it under 2.04, and it seemed to work fine.  Is there some
problem with this program?  Why weren't people pointed toward it months
ago?

     If any of you are really into seeing some cool amiga graphics, you must
 pick up the Mark Thompson jpegs called Markfilm.lha on hubcap.clemson.edu.
    Hey Mark, you've wom me. I looked at those pictures with my standard
    chip set with the public domain program called viewtek in which you should 
    get to. Keep in mind that I viewed these pictures only in HAM mode with
    352 by 480 or something. Lores, interlaced, lots of overscan. It has
    some pictures from some scenes he generated with Lightwave, Deluxe Paint,
    and quite a few other cool tools including a morphing package or two.
    Now, at that resolution, the three 24-bit pics(but in my case, converted
     to that overscan ham directly by the viewtek program) look extremely
    awesome. In standard HAM mode for the standard chip set(Mine enhaced chip)
    (doesn't matter though) I particularily like his floaty in the pool picture.
      When I viewed it, I was appauled. THe 24-bit to ham conversion would
       have most people's eyes bug out. Two things I must comment on in terms
      of neat tricks. I loved the lighting, I love what this guy does to 
      water. I would swear I could (Even in my non-AGA mode) just dive right
      into that water in the pool from where I stood. The colors and the
      interlace definitely helped to give it more of a sharp look, especially
       for the outline of the pool. I happened to notice that the store
  pic he had had rain that would cause splashes in pools of water before
     I read about it in the readme file. 
         --- Now from what I understand, this was animated?????? Boy ,I 
     would love to see it animated. Probably would pay just to go over
     and see the thing. Now, I'm still a bit new to the rendering scene, but
     from the pics I've gotten before, this one rocks the box. Oh well.
       By the way, GET THE viewtek program from your regular ftp site. It's
      the best friend an image viewer can have. It does everything I wished
     all my other programs would do, except it doesn't covert them, it just
      views all those types. Extremely system friendly. Cool standard
     file requester, Zee works!!!.

     I usually don't read this group, but now that I'm really into coding
    3D graphics for future amiga releases, I think I'll start reading this
      regularly. Perhaps it'll help me cool down from seeing those stills.

I'd say this is quite exact (although my literature says 4 million).

The question is _what_ 2 or 4 million colors and when are they visible
(due to some image processing in the eye).

    Well guy, I have used both the 2080 and 1084 with the SNES system.
And the winner is the : 1084, why ?? because it doesn't streak or ghost when
characters move across the screen like on the 2080.  Other than that it is
exactly the same monitor!!! Except the 1084S is in STEREO.

	I've gotten in excess of 30fps with 320x200xham8. This was not with an

	I would like to remind people that "summaries" are good articles
to contribute to comp.sys.amiga.reviews.

	If you have collected information about a product or category of
products, and you just post a summary in a newsgroup like c.s.a.hardware,
the summary is GONE after the articles expire.  However, if you submit it to
c.s.a.reviews, your summary is ARCHIVED on a publically accessible ftp site
forever and ever.  (Well, for a long time, anyway.)

	See the monthly "Introduction to c.s.a.reviews" posting for
more information on how to submit a summary to c.s.a.reviews.  Send
a request to amiga-reviews-requests@math.uh.edu if you want me to mail
you a copy of these guidelines, or ftp them from math.uh.edu.

	Thank you very much.

I remember from somewhere that the human eye can only resolve
about 100 to 200 greylevels locally. NB locally, because after
adaptation the dynamic range of the human eye is immense.

   Tandy has finally announced their new desktop MPC-compatible computer system
with a 16-million-color display and CD-ROM drive as standard hardware.  
It is called the "Sensation" and carries a list price of $2100.  They have
been advertizing it like mad, as you can expect from Tandy.  My question is:
when will we ever see anything like this from Commodore?  How hard could it
possibly be to stick a CD-ROM drive into an A4000 and sell it, anyway? 

   It looks like Commodore really is going to be the last major personal
computer company to bring out a desktop computer with a CD-ROM drive.  Really
pathetic.

Gentle folk,

Here's a summary of the responses to my recent posting:

me>I am interested in getting a graphics tablet for my Amiga.
me>I would greatly appreciate it if people using tablets would
me>send me e'mail describing what they are using and how well it works.
md>I'll post a summary.

One site has used the small (~$250) Wiz tablet for about a year.
It works great for tracing but has no provision for overlays.
Its configuration program lets you set the density, work-space size,
reprogram the buttons etc and save different settings into multiple
configuration files. A recent software upgrade is supposed to fix 
problems with overscan screens. 

Another person reports that he had a lot of problems with a Dakota
tablet, and was unable to get them resolved. He highly recommends
Summa tablets (1-800-729-7866, 203-881-5400 for tech.info)

A third person reports that although the Summa tablet has long been a 
favorite, the pressure sensitive Wacom tablet is fast becoming the new 
"king of the hill". Unfortunately, only OpalVision is reported to support
this feature.

	I'd guess 3000s (and others) are a too big market to miss out. A
3000 with a gfx card and a new cpu card is as good as a 4000, but with SCSI :).
CBM claims a general release for WB 3.1 in late spring, an improved 3.0 with

   I finally got around to looking at some of the screen shots uploaded to
usl.edu in /pub.  Is it me, or did Commodore blatantly copy from Apple 
Computer with the WB3.0 Palette Preferences tool?

   Are there any screen-capture utilities available that can capture a screen
with a menu pulled-down?
