Re: Doubling boxes
You've really set yourself a tricky task there! Some excellent reflections in a very complicated scene. Just a couple of points: 1. Assuming the glass table has parallel sides, and that it's flush against the back wall, then the angle of the bricks beneath should be the same as the angle of the front edge of the table 2. The reflection of the microscope mirror should show the underside of the mirror, not the top 3. Should the view of the top of the skull's headgear should be distorted by refraction through the glass? 4. I think the key has gone translucent in parts. Otherwise - very fine work. The sort of thing that would bring groans if I set it as a Friday Challenge! |

Re: Doubling boxes
Thank you for your time Steve, and for the learning points! 1. Obvious (after you let me know). 2. Didn't see this at all, but do now. 3. This was one of the tricky parts that I couldn't solve 
4. The same as 3, but I didn't notice at the time. So thanks for the help again Steve! Can't think of a better teacher. |

Re: Doubling boxes
1. Perspective works in all kinds of ways - a great help in getting things lined up. 2. This is really tricky. I struggled to get this right, and even now I'm not sure I have - the fact that the mirror is at an angle makes it all very much more complicated - but I think the reflection would look something like this: 
3. Easy to fix - just shift the top part of the skull along a little way to give the impression of refraction. 4. These reflections are made very much easier if you put all the reflected elements in a single group, then lower the opacity of the group as a whole. That way you can keep all the elements at 100% opacity, so they don't interfere with each other, and move them around as you wish. Glad to be of help! |

Re: Doubling boxes
Hi Steve, 1. The wall is fixed (perspectively). 2. The first time you spoke about setting a tricky task. Darned you were right! As a schoolboy I purchased a microscope and I got it from my attic, but the stander was to high. Then I remembered your coin at this Friday Challance! I took a mirror and used an Euro to see what it would look like as I held it in the same angle as the microscope's lightmirror. The angle of the one you draw is about the same, but the mirrorholder is a bit flatter. And maybe it seems not, but mine is 1/3 shorter than the original according the reflection of my Euro. And I've thought about the little edge of the mirror itself, including the highlight, same as you (quickly) had done. The mirrorholders has to be in line, I suppose (see yellow line). 3. Fixed (I think). 4. I should have known! In your =GREAT= book "100% Photoshop" you wrote about "Making the reflection" on page 245. For me I'm fairly satisfied with the corrections. If you're not... I hope you've got the time to teach me ones again.  |

Re: Doubling boxes
Now that's interesting: your mirror and mine are opposite ways up. You say you've tried this with a euro? I'm going to have to look at this further! |

Re: Doubling boxes
Don't do that Steve. You ware right in the first place. I went mad looking at the coin in the mirror and at a certain moment I was convinced this was the right angle. Wrong! |

Re: Doubling boxes
Well, this is the end of the doubling boxes test I suppose. And I'm not fully sure about the angle. It remains tricky. But I learned a lot again and realize I must think harder before I'm satisfied. Thanks Steve.  |

Re: Doubling boxes
Yes 'That's it!' I concur. The wall was out then although together top/bottom mismatched the table angle but now is aligned to table. having said all that I wouldn't want to tackle this. How long has this taken? And well done by the way, RetroSi... |

Re: Doubling boxes
Excuse me for this late reaction RetroSi. How long this took? When I'm into Photoshop I lost all notion of time, so I really don't know how much time it took. |
