I have now updated also the English version of my page which allows to fuse online two differently exposed pictures: www.milanofotografo.it/englishFotografiaHDR.aspx
In this way it is possible to get correctly exposed pictures of scenes which otherwise would result partially eighter too dark or burnt.
The page offers also the possibility to correct horizontal and vertical shifts, so to make it possibile to apply the algorythm also on pictures shot with the camera handheld.
There is also a help page: www.milanofotografo.it/englishFotografiaProveIstruzioniEstensoreGammaD
Critiques and suggestions are welcome!
Note: If the images are larger than 12 Mp each, there could be an error!

The image below (detail inside the church of Sant Antonio Abate in Milan) was obtained using the algorythm contained in the page.

I have added some improvements to the page. In particular there is now a new gradient shape, expecially useful with images containing bright low contrast parts!

New important update!
Now it is possible to start also from three differently exposed pictures, not only from two like before!
All the interested ones are invited to try it!

New update of the page: it is now possible to correct the shift also in case of three starting picture, not only in the case of two as before!
Try it out!
Critics and suggestions for future improvements are welcome!
The picture of the portico was obtained from three pictures on a scale of 2 stops taken with the camera handheld.

I have just added a tool which helps estimating the rotation differences between the bracketed pictures. There is also a dedicated instruction page: www.milanofotografo.it/englishFotografiaProveIstruzionAnalisiAngolo.as

I have just added to my page a new gradient, or, better, the possibility to let the system use for each pixel a mix of the two gradients, with the weights of them varying from pixel to pixel depending on the luminosity of the pixel itself and of the pixels surrounding it!
Furthermore there is now also a page which illustrates with some examples the different results you can achieve depending on the number of the starting images and the gradient shape chosen: www.milanofotografo.it/englishFotografiaProveGradientiPerHDRonLine.asp

Attention: I have found there is a bug regarding the shift! I will fix it in the afternoon!
