Troubling perspectives

So I think there's something wrong with the perspective in this image, but I'm not really sure what or how to fix it. Is it the numbers? The basic shape of the clock? The fm-band? I'd be most grateful if you could show me/ tell me what's wrong and what I should do to make it right. If it's not all in my head.
Thanks a bunch!

I think the table and the fm scale are off:



The lines on the fm scale are parallel, but that doesn't match the perspective of the clock. And to the left of the clock the table seems to be bigger than to the right. It's late and I'm tired, so I don't know how to describe it better. ;)

I may be wrong, but I think your third point of perspective, the one below the page, looks off to me. The notches for the radio frequencies shouldn't be parallel, but increasingly more angled the further you get from the focal point.

I also feel as though the angle of the bottom edge of the radio is off, but this might be an optical illusion because of the way that corner converges with the bottom of the image.

Thanks guys! Did a rework, and think it looks a bit better. Perhaps not perfect, but good enough.
Although I believe I have mastered the concepts of one-point and two-point perspective, this is the first time i draw anything in three-point. And I might have missunderstood a bit. So Eric, yeah, your probably right!
Thanks again for your help!

This is a three point perspective (birds eye), so the edges of the "turn off" button should should meet in the same vanishing point as the edges of the apparatus itself. The perspective of the frequency scale is not that disturbing , because it's probably inclined inward at the top as it should be (a very few can tell). It's a convincing alarm clock radio, but it's mostly that button atop that disturbs me. Nice work!

Lasca

Thanks for the input Denture Alley! I'll take a look at that button!

The problem is your vanishing points, you are using 2 point perspective but the points are too close for such a small object like the  radio.  Even if the object in theory has parallel sides that would move to one vanishing point the fact that they are so short the movement should be imperceptible. and I would just draw them the same direction.  So in your example I would draw the left side of the radio visable

I have to disagree completely. Aside from the fact that this thread is almost two months old, not only is two point perspective perfectly appropriate here (and in 98% of similar images), it's also well executed, and the vanishing points are nowhere near what I would call "too close" (together, I assume), emphasized by the fact that the two relevant corners are closer to 180° than 90°. In addition, the object's size is completely irrelevant to the perspective, and the clock easily occupies 50% of the image area anyway!
You simply could not be more wrong in every single point you're making, I'm afraid.

I'm mostly with Khris on this one.  Admittedly, I'd Personally call it 3-point perspective (left/right/bottom as opposed to a horizon line).  The idea of the short distance between edges baffles me, as the camera is so close to the item; it would only be inperceptible if was on the other side of the room (at the correct angle).

Whilst I'm all for bending the rules when it comes to perspective, I think you need to re-evaluate how well versed your tutor in the subject was.  Anything up to GCSE level (in my day, 15+ years ago) and they were more interested in art history, grades and copying images without understanding them than actually learning the fundamentals.

I always wanted to learn things like color theory or how light reflected, and they were always more interested in telling me what the artist who painted that semi-famous things favorite food was or getting me to trace images from a book.  Moral?  Most art teachers can't be trusted; it's better to re-learn everything from other sources.

The final answer: the vanishing points are sometimes correct, sometimes totally random.

Really...?
You are aware that moving either one of the eyeballed two points inside the pic by just a single pixel will greatly move the far end of the lines, right?
Assuming you are serious, your entire posts prompts one huge WTF in my mind.

Hey Khris, why so stressed? Here, man, have a candy. :D Now, I am perfectly aware of what you're saying, but really, in this case the vanishing points are really off, which explains why the perspective of the digits, for example, looks inconsistent with the overall perspective. Talk to you soon!

EDIT: Oh, I understand! you're the one who did the first corrective paintover. Don't get me wrong: It's 10,000 times better now, especially the grey "frequencies bar". My post didn't mean to criticize the correction, my point was to say the same thing as you: "the 3-point perspective is perfectly ok, provided it's handled properly." (and in the original drawing it was not).
 

Khris

I'm not stressed at all, there was just a huge question mark floating above my head.
The digits were adjusted by me, using the distort tool in PS. It was a very quick edit (and labeled as such) and was mostly for illustrative purposes.
Also, in the past, other people have done this folly of elongating relatively short lines only to conclude that they didn't meet. Turns out more often than not, if you start from the actual vanishing point, they suddenly do line up just fine.

My reaction was appropriate, given you used "final answer", "totally random" and "wtf".

Talk to you soon, and no hard feelings :)

Adventures should not necessarily be photo realistic; that is what really gives them charm. Create them simple, but with carefully chosen beautyful colour palette. OK I'm out.:tongue:
