Hello to all,
I would be grateful if any of you friends help me understand the limits and problems of this shot. It 's the first infrared that place on the site and the fact that it has aroused interest and / or curiosity makes me think that there is something wrong: I thought that the mixing of the color channels made to recover and enhance shades of heaven and of 'Water may perhaps not be very harmonic with the rest of the context, that this type of processing induces to think of a simple post production work with colors cloned or invented. I mean, I know it would be of great use to listen to opinions and suggestions.
Thank you
Luigi

I state that I am not an expert editing:-D and, therefore, I express only my humble opinion:-D, hoping that my remarks may lead some reflection. I think:-D that there are small defects whose sum (... . Makes total .. hee hee hee:-D:-D ... Toto !) Make sure that the frame (although overall pleasant) lose a bit of interest, a compositional level the simultaneous presence of ruins and modern construction takes away a bit of charm to the representation, then, if it is true, on the one hand, that we have become accustomed all'iperdefinizione and the absence of noise, it is undeniable that the trigger is blurry (the ruins are poorly defined) and grainy .. it seems made with a "bottom of the bottle" on the DX vegetation is obviously confused, there is little PDC, the diaphragm was perhaps too open!? I ch and despite the use of the tripod there is a bit of shake-! There was the wind ..!?) ;-) Hope I've given you some ideas ... I salute you :-) ;-)

Thank you very much, Giuseppe: your instructions I are of great use. In fact, there was no wind and the diaphragm was very closed.

Hello Louis! :-D

I do not know if my message will be of any use, since I have not ever tried to experiment on this technique ...
But riicordo that many years ago I was interested in the subject (still the era of analog).
The first impression that I got to see your picture was: "Strange is so blurry ... Usually the images are superb clarity ir ...".
I was reminded therefore a matter that concerns the recovery.
Perhaps you have taken into account, but do you have mentioned in this topic ...

Near the distance scale of many objectives, on the scale of depth of field, there is often a dash red or a red dot. If I remember correctly it is the indicator that is used to correct the plan maf on the film / sensor in the case of pictures in ir. That is, if you focheggi (on the floor sensor) normally, do not keep into account the fact that the wavelengths in ir not correspond with those of the visible radiation, so it have a slight spèostamento of maf, that with the radiation ir falls before or after with respect to the focal plane.
The procedure remember that I was to focus normally, then maf occurred, it was necessary to move the ring maf so that the distance scale which corresponded cleat on white of the scale of depth of field on the lens (the one that tells you the distance of maf), correspond instead to the cleat or the red dot above.
In practice, if raggiugi the perfect maf and laws on the lens that is accurate to 3m from the focal planeand you must move the 3m to match the red cleat.

For the rest, the matter of post production is very detailed and complex, so I have to see if I can find some pdf that I had picked up on the net and that seemed rather complete (at least to begin with) ...

I told you mine.
The problem is that many objectives of the new generation, I'm afraid not showing more red marker I mentioned.

I try updating again as soon as possible, now I'm in a hurry ...

Hello:-D
Andrea.

Andrea thanks for the info very useful! I searched the net and moving the focus where accennavi (my goals do not have the red dot for the maf in IR) should be represented by a theoretical point place 1/3 or 1/4 of the nearest point detected by maf normal (based on light waves in the visible spectrum). The problem may be (partly) resolved diaframmando a lot, but the IR-cut dvanti place the sensor of the 7D is pretty darn effective in shielding the infrared and already at f9 and 640Iso finish over 30 "of exposure; Then I read that to diaphragm too is not very suitable when shooting IR because these are longer waves for reasons related to the laws of optical physics tend to be run first in the diffraction phenomenon .. For now I'm using two counteracting old bridge (P880 Kodak and Olympus C-8080 ) and at ISO 100 with the same filtro from 760nm give me exposure times ranging from 2 to only 1/2 second (!) due to their shielding system obviously much less effective.
Thank you again,
Luigi

Imagine Luigi ...
I only regret that I can not find the pdf I mentioned, which was very full ...
I attach a link anyway (maybe you have already seen), with some mention of other useful and related links.

foto.paolo.pavan.name/ir.pdf

Then how do you know if you do a search on google, you can lose weeks of reading ... :-D

I only remember that I came to this conclusion: "If I'm going to make some attempt,
when will only be purchasing a DSLR with filter change for the if ... ".
The idea of ??working with too long and too dark filter over the lens, I do not
sconfinfera for nothing ... :-D

AspectsTero to see your results and then, in the event, I will try to imitate you ... :-D:-D:-D

Hello, you next ...
Andrea.

You're very kind Andrea, thank you so much for the help: I'll try to calmly see what'll get you out, and if it proves interesting, I will buy an SLR also changed.
See you soon!
Luigi
