Tutorial: Almost Hell

 

 Ethan on Making Light suggested a mashup between this Kinkade image (title: Almost Heaven) and this Call of Cthulhu image. I was happy to oblige. Click through to see larger.

 

 

Here's how to do a fast mashup.  You don't need to have strong photoshop-fu, I promise! You don't even need photoshop, just an app with layers and a precision lasso--that is, one where you draw the line with multiple clicks, rather than dragging the line.  Transform tools are good too.

Then, choose two images with reasonably similar lighting and get started.

For this image, my steps were:

  1. Drop the water/background image on the bottom layer
  2. Drop Cthulhu on the next layer
  3. Cut out (with the lasso) or erase (harder than lassoing, but doable) all the parts of Cthulhu I don't want, being careful to keep all of his tentacles
  4. Put a second copy of the water/background image onto the layer above Cthulhu
  5. Erase the upper part of the water image until I've got Cthuhlu looking sort of like he's emerging from the water. Erase the bits around his tentacles so that the tentacles are on top (even though that looks fake).
  6. Pull up another copy of the original Cthuhlu image and use the lasso to select a big water splash
  7. Put the water splash on the top layer and use it to disguise the place where Cthuhlu emerges from the water
  8. Copy bits of the water splash and flip and turn them to cover the tips of his tentacles.  Turn the opacity down on some of these layers if necessary to add variety.
  9. With the lasso, select a very thin line from the tip of the fishing pole to Cthuhul's mouth
  10. With the eyedropper, click the fishing pole to pick up its color (light greyish)
  11. Use the "stroke" function to do a 1 pixel stroke of the selection, thereby creating a fishing line
  12. Deselect All
  13. Flatten the layers

Ta-da!

Drawing on the computer - a breakthrough!


Wacom drawing

I've had a Wacom tablet for years. It's great for all kinds of photoshop & painter stuff, but I've never been comfortable drawing with it because the pen slides around. The surface of the tablet's got no "tooth," which is a drag. I was showing the tablet to an artist friend and she noticed the same problem. In a solution so obvious it's got me slapping my forehead, she put a piece of paper on top of the tablet. Works great, nice tooth, easy as pie to draw with. I cut the paper to match the screen outline on the tablet and taped it at the top and the bottom. This is what I've drawn with it so far.

1. Corel Painter for $200 2. I am unspeakably lazy

Corel's selling the newest version of Painter (IX.5, they're calling it.  Shouldn't that be IX.V?) for $200 through the end of May, marked down from its usual $450 or so.  You get the full version for the upgrade price.  Painter is the caddilac of natural-media paint tools so if you're into that you should check it out.  Just remember it goes back up to full price on June 1.

On an unrelated note, what does this say about my laziness?  I got a frozen "seafood scampi" dinner (Stouffer's, I think).  It wasn't bad - decent noodles & sauce, pretty ok shrimp, and bad little scallops--tough and really fishy smelling.  After eating one I thought "ok, I'll just toss the other 4 scallops and just eat the shrimp and noodles."  Then I thought "I don't want the scallops in the kitchen trash making the whole place smell like fish!"  So, rather than have to take the trash out after tossing them, I just went ahead and ate the rubbery little beasties.  Soooo lazy.

Building a new PC, part two

All the parts and bits have arrived and Hub has put everything together for me (I know I said I was going to build it, but hey, he wanted to do it, and I'm lazy.)  I opted for this case and dual 19-inch LCD's so my workspace is much cooler and prettier now.  Will post a pic in a couple of days.

So far I've installed Cinema 4D, Poser 6, Vue D'Esprit 4, Sid Meier's Pirates, Sims2, and my old y2k edition of MS works+ word.  Tonight I'm installing 30-day demos of Photoshop CS2 (planning to buy, but ouch, not cheap! so will wait til demo runs out), XFrog for C4D, Painter IX, and Paint Shop Pro X.   Paint Shop Pro has some nifty features that Photoshop doesn't.  Painter I'm just trying for a lark - I'm not really a digital painter so it's probably not worth the money to buy it, but I may as well enjoy the 30 days of noodling.

Probably what I'm the most excited about is getting Dreamfall (Longest Journey 2).  I loved The Longest Journey like it was a kitten.

So, that's what I've been up to, and hence not blogging much, but I promise many scintillating posts soon including:

Building My Own PC, Part One

So, at long last it's time for me to buy a new PC.  My current one is a 4-or-5-year-old Dell, which was smokin' at the time that I bought it, but now is wheezy and tired.  The good thing is that it's encouraged me to write more, because writing doesn't require huge gobs of memory or a zippy processor.  The bad thing is that I have several 3d modelling projects that could be earning me actual money if I could finish them without pulling my hair out.  When it takes 30 minutes to render each product display image, problems like "gee, her head's at a funny angle in that one" become nightmares of Ropsian proportions.

See, I work in a variety of 3d apps.  Right now the only one that will render images efficiently is CINEMA 4D.  That's the one I use for my modelling and for most of the images I make for fun, including the bubbling bowl up at the top of this page. (See my main site for more of that sort of thing)  But the products I sell are mostly designed to be used in Poser or Daz Studio.  So to give an accurate idea of what they really look like to customers, I have to use the tool that the customer's going to use to render them.  Sigh.  Poser & Daz Studio render much, much, much slower than CINEMA 4D (They also cost much, much, less...you get what you pay for).  On a newish computer, you'd like them just fine. They'd seem zippy.  You wouldn't sit and say "for the love of GOD how long can it take you to render a single figure with a WHITE BACKGROUND!  I could render a big leafy TREE in C4D in that time! AND MODEL IT!

So, I've decided it's finally time for a new workhorse.  I've got some money saved up, so I can (within reason) buy as good of a PC as I need.  I figured I'd get the Dell XPS 400, because it's fast, designed for gaming, and I can get it with 4 gb of memory.  Buying a prebuilt system from an OEM vendor has advantages like 1. you can get support 2. you get a deep discount on your OS and other bundled software 3. you typically can also get a discount on your monitor.  And folks, I want the Dell 20-inch widescreen ultrasharp flat panel.  Oh yes I do.  I'm going to keep my super-sharp, beloved little dell 17-inch trinitron CRT, and hook it up to the second video port, and be in pallette heaven.  With 2 monitors you can work your main image on one and put all your pop-up palletes and crap on the other, and never have to go to a menu to get a tool.  Mmm, I can already imagine it, what a wonderful world it will be.  Plus, the widescreen can rotate into portrait mode for reading blogs or what have you, so that's nifty too.

Hub did a very nice job of convincing me that I was going down the wrong path with the actual system, though.  Darn him.  He suggested that before I spend my money mostly on memory and just accept Dell's idea of a good processor (Pentium E), I open "perfmon" and try rendering some things and performing other tasks in my art apps.  

Well, what I discovered surprised me.  I've thought, for all these years, that rendering takes place mostly in memory. As it turns out, nuh-uh.  It's mostly on the processor.  Photoshop is the real memory hog in my toolbox; Poser and Cinema4d want more processor.  So we googled around a bit to see if C4D can make use of a Dual Core processor, and found a benchmark test comparison of Athlons and Pentiums that used C4D as its benchmark app.  The Athlons won in both the really-expensive category (the 4800+ vs the Pentium EE) and the less-expensive category (3800+ vs the Pentium D).  So that means I want my system to start with a dual-core Athlon 64 X2 3800+. I don't think I'm going to want to bother upgrading to a 64-bit os anytime soon but Hub recommends having the option, and since I didn't think to check my processor utilization in the first place, I guess I should listen to him.  I'm actually pretty miffed with myself because I'm a professional engineer, and I should use the same decision-making methodology at home that I do at work, and I didn't.

My punishment or reward for this is to build my own PC, although I will probably wimp out and let Hub do the tricky bit of seating the processor onto the motherboard. (When I'm working on a $10,000 system at the office, I insist on doing all of this stuff myself, but when it's my own money, I go all girly and let the man do it! Sigh.) I considered getting a prebuilt from HP, because they have Athlon processors and those cool Lightscribe DVD writers, but their video card selection is garbage.  And it's cheaper to build it ourselves--even with buying a genuine legal copy of the OS and all that.

So we're going to Fry's Electronics tomorrow to fondle components, and with luck we'll find a case on the shelf that I'll like, since I do insist on having a cute case for the thing.   In the event that we don't, I poked around on Newegg  to see what's cool.

First, though, I googled "cute pc case" and found this:

I have to admit I'm tempted!

Self Portrait Tuesday

 

For my first Tuesday self portrait I've chosen a CGI image.  I spend a lot of my free time noodling around with 2d and 3d computer graphics.  This image was made with ArtRage, a free paint app.  One of the nice features of the program is that you can put virtual tracing paper over a photograph so you have a guide for painting. (You can also paint directly onto a photo).

You can get the software at http://www.ambientdesign.com/artrage.html.  There's a free edition and a $20 edition with a few extra features.  It's a lot of fun and if you've never tried computer graphics, it's a very good place to start.
