comment What tools are available for RAW image processing in Linux?
This one got especially well in the latest release. Everyone should give it a try!

comment Should I keep Image Stabilization (IS) off when I do not actually need it?
Check this question: photo.stackexchange.com/questions/7848/…

comment Getting started with Pano software?
It might be buggy working with big files (memory issues), but for other things it works very great, it can even create HDR bokeh panoramas, you can play a lot with the options it offers.

comment What is “bokeh panorama” (also called the “Brenizer method”)?
I forgot to tell you, those focal distances aren't 35mm equivalent. So you would have to multiply them by 6 times. So the 70mm focal distance of my camera equals a 420mm in 35mm format, which is a very narrow angle. Having said that, I think the final image would have a much bigger aperture (i.e. f/0.8) am I right? Is there an easy way to calculate the equivalent f number when the final image is done?

comment What is “bokeh panorama” (also called the “Brenizer method”)?
In my P&S with 70mm of focal distance with the maximum zoom, the aperture is f5.9, slower than f3.1, which is the aperture my camera has when the focal distance is 5mm. Why is that happening?

Should I change "Benizer Method" by "Bokeh Panorama" in the question?

Thanks for this very detailed answer!

comment How can I simulate a long exposure photo using a set of shorter exposure photos?
That is a great idea, because the noise produced in a shorter exposure, will be averaged in the stack. Or I think so...

comment Intervalometer ideas?
I specially like the idea of taking aerial photos with a kite, but I'm concerned about any damage to the camera caused by a fall. It seems I'll have to figure out how to make some kind of box to soften the hit, or a parachute could be also a good idea. Do you use any protection?

comment How do I reduce noise, given that I have complete control over everything else?
"effectively simulating the result of using an ISO setting lower than the camera could ordinarily produce" That could be the conclusion we can extract from that experiment... Was that was already known?

But how can I be sure I won't blow highlights?

comment How to fill my time-lapse video with more frames?
Yes, but a second (or third) battery wouldn't help if I'm running out of battery in the middle of the timelapse. It'd be helpful in the case I want to start a new time-lapse right after the other.

comment Is there any noise difference between averaged and long exposure photos?
@jrista: The fixed pattern noise you're talking about, is the one corrected with dark frames, right?

comment Is there any noise difference between averaged and long exposure photos?
Well, I used I tripod although it's a Chinese brand (and also very thin) so the quality is questionable. To shoot the photos, I used a script so the movement is between each set (when I press the shutter) but there should be no movement between the photos inside each set. And last, remember my camera is a Point and Shoot so the overall quality will not be the same compared to a DSLR.

comment Is there any noise difference between averaged and long exposure photos?
My merging approach is just deleting noise. If I'd want a higher dynamic range in my image, I would have taken different exposure photos and then yes throw them to the fantastic enfuse! In this case, I don't think enfuse could do something better than plane averaging.

I've never used a script in Gimp. How would I execute it? From the command line, or from the program. Should I save that as a script?

comment How can I simulate a long exposure photo using a set of shorter exposure photos?
That's not what I would want for stars. Because they'd be averaged with the other frames, making the sky empty!

I think I've done the same experiment. Check my EDIT

comment Is there any noise difference between averaged and long exposure photos?
When I tried to write the question, my point was: 1 image with low ISO and longer exposure and a series of images (averaged later) with higher ISO and a exposure that equals a/n, being a the exposure time of the low ISO image and n the quantity of high ISO images. But all of this speaking in terms of not blowing nor underexposing any of the images. Can I explain myself?
