Need some perspective on "perspective"

[w1as]

why is the horizon inclined?

Well, I had thought, It wouldn't matter what angle the horizon line was situated, but now I'm thinking differently. :shrug:

Hi Daniel!
Well, I want to help you (if I can)

You are talking about a non-represented (for the moment) cage, ...right?
Why do you say that your attempt is "funky"?
If I don't mistake, as you said, you must "just to turn" the cage (create a new vanishing point) towards the existent horizon line.
Perhaps can you show us the try ...it could be useful.
Bye

error : I said ONE point, I wanted to say TWO points of course...
I am still thinking at your problem, and tomorrow (if I have time, because it's the presidential voting in France:))I 'll begin some research to find a clear tutorial about this...(must do housework in my old documentation...)

I know what you mean, it's easy to determine the first point, but the second one?
bye

Thanks, arnocob, I gave it a second try since you confirmed that one can have more than two vanishing points. This time, though, I created it further from the center of the page and it worked just fine. I guess, my first attempt, I placed the extra vanishing point near the center and the perspective naturally became forced and distorted. In any case, problem resolved :) Thanks again!

Oh, here's an update of the rough. The cage is just slightly skewed to add some interest.

Ok.
BTW, I like the compo and subject!
It becomes great. Perhaps that the lighting on the cage disturbs me a bit...(where is the main light source?)
Actually, the cage seems to be the main subject of the painting..
Just a suggest:with an obscured foreground, the prof and the creature could become the main subject...
I know that it's a WIP, I didn't want to crit a lot!
bye:)

Thanks arnocob. Yeah, you're exactly right. The values on the cage are not established at this point. I just wanted to get the perspective done, first. In the end, the cage, skull, rat, shelf, etc., will be composed mostly of dark values and will serve as a strong foreground silouette (spelling?) The center point will definitely be the Frankenstein and the monster :)

Thanks for your help and suggestions :thumbsup:

Hello Daniel

Iwill be definetly observing your progress since i am cracking some perspective problems myself. Im sure it turns out beautiful. But i have sometning i want to ask...how do you draw your perspective cage in photoshop- how do you get it to be outside working area? is there any way to turn the guides?
Anyhow i dont know how:cry: i am using ps for 3 years now and i still dont know that....i remember that i got some tips on this awhile ago but i forgot them...

bye:buttrock:

Not a problem, Arlekin :)

I think a lot of artist's use the path pen tool, because you can go outside the canvass space. Unfortunately, I hate the pen tool. What I do, is create a larger document (dull yellow area) and on a separate layer create the actual composition which will be much smaller. This configuration gives me room to use the line tool to click and drag lines from the points along the horizon line. I generally house the horizon line and perspective lines in a separate folder so I can easily hide them when needed. Here's an snapshot if it helps. Good luck and let me know if you have anymore questions.

looking forward to see how it will end :)

But, what do the dark blue lines represent? Why is there a different vanishing point for them?

the blue lines are for the cage in the lower left of the painting. the cage has different vanishing points because it is rotated relative to the walls.
