View Full Version : Perspective Volume One with Carl Dobsky
MassiveDVD
August 1st, 2008, 08:46 PM
In the first section of this download, Carl takes the viewer through three perspective setups. In the first, he shows the viewer how to
set up a basic square grid in perspective while covering such topics as the station point, measuring points, picture plane, and the cone of vision. In the second setup Carl covers the concepts of the measure bar and anchor point in order to create a cube in a precise location in pace. Lastly, the viewer is shown how to take an elevation view and project into 3D space.
In the second portion, Carl takes a simple thumbnail sketch and fleshes it out into a finished picture. In doing so, he expands upon many of the techniques in the first section. While watching this video, the viewer will see how a professional artist applies the rules of linear perspective to fit the specific needs of a painting. This download works for both beginners as well as professionals in need of a refresher.

I've been wanting to hear mr.Dobsky's thoughts on art for a long while. Seeing as how I (ahum) first heard of him through here and hear everyone praise him I think it's about time I get some insight into his work also...
Plus, perspective is always interesting to get new views on..

You can still get the basic winrar from CNET.

I've been running the trial version forever and a day. As long as you don't want to do anything more complicated than extract the files, you don't need the full version. Sometimes a message will pop up asking you to get the full one, but can just right click the .rar file and select"extract files here" and it'll still do what you want it to.
Hope that helps

This was outstanding. Not only did it explain how to use perspective, but he actually helps you understand why it works. I will definitely be getting other DL's from Mr. Dobsky.
I have two other comments/concerns.
First, the audio does not match up to the video. I tried it on two computers, is this happening for anyone else?
Second, I understand if you want to edit out swearing, but PLEASE don't use a beep that increases in volume. It is just as easy to mute the sound, You'll still get rid of the offending word, but in an unobtrusive manner. I have almost every download, and every time you put a beep, it is loud and extremely jarring, especially if the speakers or headphones are turned up. Please consider.

This was pretty good! Even the Scott Robertson DVD's did not explain how to draw a geometric shape receding into the distance with accuracy (although he did touch on it a little)!
Being a traditional painter I might have liked the tutorial been done by real pencils and paper rather than using the preset shapes within photoshop (square and triangle). Not a big deal, i thought i would bring it up.

People should really get this. I've seen Feng's stuff and other peoples' attempts to teach perspective, but until you've heard of a measure bar you've got no idea how it works.
I did a lot of technical drawing in high school (sometime in the late forties before television came along) and Carl's the first guy in the entertainment industry who's ever given it straight (to me anyway. yeah you know what i mean).
I realise some noobs will miss the fact that there aren't any boss monsters or whatever being drawn here, but if they're all so concerned about accidentally becoming marko and wes clones, maybe they oughtta just learn about the poetry of space from dobsky instead.
Oh I don't know if Dobsky says so, but it's usually recommended that you drink during perspective.

By the way, I've got a question. To place your Ground Line, do you measure from the Horizon Line or from the Stand Point? I'd say it's from the HL but I'm a bit confused.
Also at 28:40, Carl says that he measures 4' from the point on the right (which is at 2' from the Center Line), but he only draws 4 ticks. In other word he measures 3' instead of 4'. Same thing with the "balcony" later on which he places at 6' saying it's at 7'. Did I miss something? When he draws the wall later, he measure correctly, so I'm guessing there is a mistake there.
Carl Dobsky
August 12th, 2008, 07:58 PM
Igor-- Good eye man. I'm glad someone was paying attention. You are correct. It was 3 not 4. And 6 not 7. You didn't miss a thing and understood it perfectly. I did all of those live without a preset script or guide to follow. So I was making it up on the fly. For anyone who has ever demoed something, you know how many crazy things are going on in your head at once and I must have counted the tick marks and not the spaces. I'll go back and re-edit that. Thanks for pointing it out. Hopefully no one else gets confused by that.
To place the height of the eye, measure down the CL from the HL. That's where GL is. Hopefully that clears it all up.
Thanks everybody for the props on this one! I wasn't sure how much interest there wold be in the subject but it looks like there was way more than I expected. We're working on the second one so keep an eye out for that. It'll be coming up soon. I've got a good feeling about it too.

Excellent video, just finnished watching it.
I had issues with the sound on the first vid (it moved from speaker to speaker in the first 15-30mins) but that has been adressed, Could hear perfectly what was said though so no issues with that.
In the second part, when "sweetheart" gets to doing the base of the statue, it seemed for a while like the far-base was WAY off perspective-wise because he didn't mention the fact that the most bottom part also is slightly tilted and not perfectly vertical.
The only reason I saw that was because it shows on the frontal.
Minor thing really.
Also, might be me, but on the first part, when doing those tiles, as the line from the GL to the MP crosses the center vertical line, it looks like the tiles created there are smaller (shorter in depth) on one line.
I marked one of the tiles in green. the lines above are made with a smaller brush but it still looks odd and so I was wondering wether this is an optical illusion because the spot where it happend also happens to be almost the dead center between the horizonline and the GL (bottom line for the tile is on the dead center)...

If you look really hard, you can probably find more little inconsistencies too.
Like I said, I did these "live: so everything was on the fly so to speak. Things like that can occur because an angle is barely wrong. Sometimes a pencil or pixel width can matter for perfect accuracy. At any rate, my hope is that people will have learned the principles and understand how to apply them. Hopefully, we've done our job and I'm sure the next ones will be even better.

I wasn't looking for errors, just thought this might be one of those optic illusions that sometimes art play on us. But the "one pixel can make a difference" makes sense also :)

Hi,
First off, I want to say thanks for this tutorial, I think it may actually be the very best 20 bucks I've spent this year. It made very clear for me several things that weren't before, especially about the cone of vision and what that actually represents.
If you don't mind, though, can you clarify a couple things for me?
1. the last section of the 1st part, with the demo of the wall of the building, I'm getting the impression that the wall is I think around 7 feet high and the top of the door and window are approximately 3 7/8 feet high because ground line is 4 feet high? Therefore, if I wanted to make the front of a larger building, like a city bank or something, I should just simply be able to scale the measure bar up proportionately larger? So that if i'm designing the front of the building on paper, I wouldn't need some ridiculously large sheet of paper to do say a 7 story building? I can just design it with the different scale, and proportionally transfer it to the scale of the drawing?
2. Also, I've tried to do an image where the viewer is on the edge of a cliff several hundred feet high - and the viewer is about 6 feet tall. But if the objects are below the ground line, how does one calculate the grid for that? Hence, is the ground line actually where the viewers feet are, or the actual ground that the grid will lie? (You may have guessed that the picture I was trying to draw looks like crap, I can't seem to get the objects to look correct.)
3. How does one determine a good distance for the picture plane from the viewer? Should it be based on the largest object in the picture, or some other measurement, like 'arm's length'? Or should it be the based on the cone of vision and the cone circle be arbitrarily laid out, kind of like you said when you reverse engineer your grids?
Sorry for all the questions, and thanks again for the video. I'm looking forward to the next one, I hope you release it very soon!
Carl Dobsky
August 31st, 2008, 08:37 PM
Hey Devlyn,
1- I'm a little confused about the question. But I think the thing to remember here is that objects are to scale at the Picture Plane. For convenience, in most set-ups this is where the Ground Line is because that is the location in space where the ground intersects the Picture Plane. You can set this scale as anything you want- 1 inch : 1 foot, 1 cm : 1 kilometer, it doesn't matter as long as you keep everything in the picture consistent with that scale.
2-Technically speaking, the Ground Line does not have to be on the ground. It's just a plane that intersects the Picture Plane at a given distance below the eye. If you're on a cliff looking out and you need to make the ground below, just measure the distance down the Center Line for the height off the valley floor and then move things back into space from there.
3-That is totally up to you. It is actually an artistic decision. A smaller distance to the PP makes the image generally feel more intimate or like you're in the middle of the action. A further distance to the PP makes it feel like you're looking out into the distance and usually has a bit more of a calm feeling.
Devlyn
September 1st, 2008, 11:11 AM
Thanks for the clarification and sorry for the bad wording of my first. In fact, in rereading it, i've confused myself. Not only that, I was thinking about it for myself for a while and then realized I may have been asking a goofy question anyway. I'm going to try to rephrase it a little here.
In using the horizon-line as a measurement of the height of the eye-level, for example 5 feet, and I wanted to add a building say 4 stories tall, given that a story in this case is 10 feet or 40 feet high in total. On my picture plane I've established that 1/2 inch is 1 foot. So to create the measuring bar to delineate the separation of the stories on the picture plane i would need 5 inches for every 10 feet above the ground line. For a 4 story building I'd need a measuring bar 20 inches high to give myself the required 40 feet of the height of the building. But my paper is only 8.5 inches high and I'm starting about 3 inches from the bottom, giving me only 5.5 inches to work with or 1/4 the required space for the building's measuring line. So I guess I could tape several sheet's of paper to get the necessary room to make the measuring bar. Soooooo...
I was thinking (uh oh) that I could double the height of the horizon line and make the measurement from there, for example, but when I tried I realized that I'd only get 10 feet for every doubling AND when I experimented, I could plainly see that it was incorrect. So the 'stacking' of horizon lines wasn't going to work. At least not the way I was trying.
So I attempted to 'shrink' the measuring bar to fit the paper, so that instead of a 20 inch bar for the 4 story building, i wanted one that was closer to 4 inches and said that every inch of the smaller bar represented 5 inches of the original bar. then i'd try to expand it upward, but, I couldn't seem to get that to work either. I suspect that in order for that to work, I'd need to alter the location of where the base of that measuring bar was placed.
When I try to place structures in my environments, they always end up either looking like toys or some kind of colossal juke boxes or something. How can I get a 10 story building in my image to look legit, the way you guys can? and all the detail too look like it is also in scale and proper proportion?
Thanks again for taking the time to answer - I know you guys are busy. I hope my question isn't totally stupid and that it is worthy of your consideration.
Thanks!
Devlyn
September 1st, 2008, 01:55 PM
I think I figured it out - I just had to stop being obtuse and think about it for a minute (or in my case, a couple hours...)
Instead of creating a measuing bar for the levels of the stories, I used the ground line to horizon line as the meaurement and simply stacked them. I was able to create a line 24' high ticked off at 4 foot intervals without the need for a measuring line 12 inches high on my 'paper' when i had only 5 inches available.
So here I illustrated what I mean and maybe you could tell me if this is correct?
Edit: Oh, and I used 1/2 inch = 1 foot so the distance from HL to GL is 2 inches or 4 feet.

Devlyn,
Way to go. You figured it out. It is in fact, 24 ft. You could have also measured the vertical( 24') from your GL and taken it back into the VP and you'd still get the same answer. That's one of the things to keep in mind. There's usually more than one way to figure out how to get from point A to point B.

Amazing stuff. I love how you never at any point lower yourself to saying 'just accept that this is what works' you go to a massive amount of effort to really explain WHY these techniques work the way they do!
Im just really really really excited for volume 2, please dont keep us waiting long, i start uni in a few weeks time and want to have 2 point nailed by then! Pretty please!!

Why the hell isn't this stuff taught more?! I'm in my last year at "art school" and I haven't heard of any of this. I was only ever shown the basics of perspective, "this is a horizon line, this is a vanishing point...etc..."
I do have a question though. After doing this several times, do you start to develop a sense for where your picture is going to get distorted, even while you're thumbnailing?

Yeah, got it, loved it, learned a ton. Can we have any hint on when v2 is coming out? days? weeks? months? years??!! :)

Gonna have to second the comments of many of the rest of the posters here: Learned much from the video--didn't understand everything on the first watch through, but that's what rewind is for. Looking forward to volume 2. Any hints on timeframe?
Cheers Carl and to the rest of the MB dudes and chick-dudes.

Carl got really busy with his MB schedule but we've resumed work on part 2 again so hopefully not too long! :)

Sweet vid I've never had linear perspective explained so concisely before. Carl does a good job of rather quickly moving through the theory behind the method as well as showing it being appllied. the only thing i've still been having trouble understanding comes in around 13:42 or so when he's initially setting up his cone of vision and is determining a scale for the drawing. He picks a 1" = 1' relationship and then (and this is what stumps me every time) seemingly arbitrarily determines that a station point at a distance of four feet from the picture plane along the Z axis/depth/ line of sight will translate onto your 2-D work surface as being four or so inches below the Horizon Line but measured along the Y-axis/height/Center Line.
I'm pretty sure it goes back to Carl talking of how the old masters basically took the cone of vision and 'bent' or 'folded' it down, but it is still unclear to me why this works so neatly, and if anyone could elaborate on the principle behind it or possibly diagram it differently than in the video it would clear up alot for me.
It seems that if i think of the cone of vision as a physical object what we are doing is rotating it's apex(station point) downward on the X-axis/Horizon Line so that the base of my cone as created by the picture plane is now perpendicular to the picture plane with so that now it's central axis is flush with the picture plane in which case any measurement of depth would translate as simply as counting the units as a measurement of height from the Horizon Line.
I'm not sure how good that explanation was but i was wondering if my thinking is going along the right lines or if my interpretation is still not quite accurate.

@ KLEVR:
I think what you're having a problem with was addressed here. (http://www.conceptart.org/forums/showthread.php?p=1878467#post1878467)

Hhhmmm... it's not quite answering of my question since Igor was asking about the GL and my question was about determining the SP, but i think i actually do understand it, Dobsky's explanation was just so brief that it continued to elude me but I think I've got it. If there are any problems with my diagram please note them to me

cool, it had me scratching my head for a solid week, so good to know. It intuitively made sense to me, but i wasn't able to really pinpoint why it made sense, so it's comforting to understand the actual mechanics of what's going on from a theoretical standpoint.
Now to muddle through two-point perspective and wrap my brain around that for a bit, I'm loving the videos, it frustrates me that foundational stuff like this isn't taught in greater depth, I'm not in school, but was talking to a friend in the local art dept. and I understood more on the subject after watching the vids than he did after three years of art school and I was thinking to myself what the hell are they teaching these kids if they don't have a solid grasp of necessary basics like one-point perspective? I wish more time was spent on teaching these kids techniques and working methods instead of encouraging them to simply slap paint on a canvas and then talk about its profound philosophical meaning as an expression of their feelings; I'm all for personal expression, but i think rhetoric as such too often serves as a crutch for these students allowing them but be lazy about improving their methods. But i'm done griping. Thanks again. Looking forward to being baffled by the three-point perspective video!

I know it's been a while since this video came out, but I recently watched it, it's really great, I'm learning a lot, but I have a question.
When finding out where to put something in space, you showed how to find out how far back an object was after finding out the distance to the right or left. When you measured the distance back, you counted the tick marks starting at where the line was drawn. This isn't making any sense, should you count the tick mark which is one measurement away from the object on the ground line first? If we count at the line as 1, if you were to have an object that was 1 foot away from you in space, it would be directly on the ground line, therefore not in perspective.
I have a diagram in which what is drawn is 2' to my left and 1' back in space. Did I do it correctly, or is the measurement wrong? Would that count as 2' back in space?

Flakari Leader: Hi, your question was adressed on page 2 (post #55 and #56). I was wondering the same thing myself.
By the way, thank you very much for an extremly informative video!

Thanks for a great video, I'm going back to classes in September after (cough cough - a lot of) years away so I'm trying to brush up on the basics that I have forgotten or never knew in the first place! I'm really enjoying the first one, will pick up the second once I've got a handle on this one!
