table_hdr
My first HDR.
I used Qtpfsgui to create this image.
I used both the Fattal and the Drago Algorithm, then I merged them in Gimp using the fattal image in a strong light layer.
To reduce noise in Fattal Algorithm, you have to push alpha and beta factor up, and create the HDR using a lot of images, with no more than 0.7 EV between images.
I know it’s gonna be tricky, but that’s the only way I could get rid of noise.

What is HDR?

HDR means High Dynamic Range. Someone would say "low contrast".
With various tecniques and algorithm, you can combine different exposures, so that an algorithm will combine them together.
This pic was just an experiment.
A normal pic wouldn't show both the most light parts and the most dark. Instead, combining more than one pic, I can see both the lamp bulb and the sheets inside/under the table
I do not like so much this heavy post-process, but there are great hdr pics on flickr, so I wanted to learn.

I did similar things when I first started using HDR. Qtpfsgui is a decent program, and I find that mixing two or more algorithms always works best.
Fattal is great, but the noise really is a killer. I usually use another algorithm with more realistic tones and less noise to blend with it.
Enfuse is also really good. I don't think it has any settings to change, but the image it creates is very good.

Yes, I know about enfuse, It's quite different from conventional HDR.
And yeah, fattal's noise's a killer, so I use to blend a fattal layer with layers done with some other algorythms.

I just found out about enfuse recently myself, but after running some photos through it I ended up with something almost exactly the same as the version that I spent loads of times trying to blend effectively.
But the different algorithms and settings in qtpfsgui definitely lend themselves to lots of experimenting.
I love this shot, great work.
