Alexander 6, V84.

 I've determined to break the spell of Mondays this Monday, but I'm not sure I'm succeeding with this or not! So far, not much annoyances!
I've finally signed for my leave, for 33 days (including holidays and weekends, which will be added back to my leave's account later on). It shall start from September 26th till October 28th. I will be back to Kuwait, hopefully after spending the vacation in Ireland then, by the 16th, and hence I would have 12 free days to spend around here before starting to work by November. Just like the last year. It was a real mess to ask for this leave because of the stupidity hovering over this place; some people do it by paper and some people (like me) must do it electronically in this damned system. Last year, when I signed for such leave from work, they dropped down the salaries of 3 months in advance into my account, and that made me some troubles in some aspects. All the fuss was to make sure that I get my salary regularly as it should be. I really don't know who makes such stupid laws!!! Be sure if I knew him or her, I'm going to assassin them.

Spent my day yesterday downloading the pictures of the panoramas taken from the labs and my office. Also, I took several free images from the outside of my building which is now like a battle field with all the reconstruction work going on and all the bricks been thrown away and made into piles and hills in front of my work place! The total number of images exceeded 300!
Coming to measure it:
  • Each row needs 12 angular shots.
  • Usually, 3 vertical angles needed.
  • Not always but count it in, one zenith and one nadir shot, total 2 (and can be 4).
  • We have here 3 rooms.
  • Going to shoot into HDR, means we need exposure bracketing, and that means 3 shots in each angle.
  • Total: 12x3x3(HDR) + (2x3) = 114 shots. For one room. All 3 rooms then are 114 x 3 = 342 shots.
Adding also those tiny shots I took from the outside which I can't remember how many, then I would say it easily exceeded 350 shots. All in RAW format (to allow me for more manipulations before merging into HDR, specially when it comes to the White Balance factor). Because of this, a 8GB CF memory card is essential!

The process of stitching was fair and went smoothly, even for the narrow lab or what we call here the "anti-compton" lab, after a device of this time. The main work now is to enhance the zenith and the nadir, which are naturally, almost always hard to stitch. In fact in the 2 labs panoramas, I've taken the nadir but I decided not to put it on the stitching process. The best thing to do probably is to clean the nadir BEFORE the stitch. I find cleaning AFTER the stitching process is over is a bit hard to do because of the wide are and the stretching that occurs naturally for the bottom of the image (because of the spherical projection of course). Usually what you see in QTVRs is that the artists put or fix some sort of a label including the name of the artist and the location and/or the date of creation. Maybe I should do this and spare myself the headache, even though I don't know how, still.
So far though, I got 2 tiny problems. The first was that in shots taken at a lower angle (pointing the camera downward that is), parts of the tripod shown up and hence, we have to do some cleaning and cloning job here. The second one is some weird artifacts occured in the Gamma Lab panorama, and they looked very much like parallax errors, but some inspection into that revealed to me that for some reason (and maybe it is even my own mistake when the shoot was on), some slices of the panorama were having a lower range of exposure (i.e. darker) from the other slices surrounding it, thus when the computer blends in together all the slices and trying to find a suitable blend, you get smudges that would look like more like breaks or like some ink plots. To fix this problem I opened those slices individually, and opened some adjacent slices for comparison, I then raised the exposure value for these dark slices to match the adjacent slice, as much as possible. The process was "fine" but issued some noise that I need to smooth out later on, after tone-mapping.
There were also some weird noise not related to the problem above, appeared as some pink spots on some various areas. This problem occured mainly after tone-mapping, but hopefully it is easy to eliminate.

Can't wait to leave this office and get back to work on these panoramas. The real challenge now is the office panorama, in which I included myself in. A moving object in a panorama shoot is not a sweet topic, at all!
1993. Alexander felt a headache and looked around hime
1994. he recognized that he is in a small house made of wood
1995. then he looked at Kaliván and said: where am I?
1996. Kaliván replied: in my humble house O hero!
1997. then Alexander asked: what happened?
1998. Kaliván then went on telling the story
1999. "you made the Mikanazzar fly away from the tree,
2000. and when it got angry it attacked you with rage,
2001. thus it passed through your heart and body,
2002. and took some of your power and made you weak,
2003. and you fell down and fainted with no power to move,
2004. thus Aramramátáníth chased after Mikanazzar,
2005. and she banished him out of the valley for now,
2006. then she endowed you with some power to heal,
2007. you will need some time to rest for now,
2008. she ordered me to take you home and care for you,
2009. until you become sound again, she shall talk to you,
2010. Oh! what a great honor is that to have her talk to you!
2011. you must be someone special O good king!"
2012. with a little headache Alexander asked Kaliván
2013. "you brought me to your home? how that is possible?"
2014. and Kaliván answered him with a laughter
2015. "thank your Cadid, he is a loyal servant for you,
2016. I released his chains and he helped me"
