Simple made, HDR Picture using Picturenaut. its free

Friday, April 17, 2009

i want to share how to make a HDR ( High Dynamic Range) Picture using my S700 and a software named picturenaut ( its absolutely free ). HDR made from 2 or more picture with different exposure.

the preparation, you will need a good stand for your camera, remember that you will take at least 3 same picture with different exposure. best tool is your tripod, or at least please stand still.

you also need a camera ( of course) the best thing is if your camera have auto braceting mode. so you can take 3 differnt exposure automaticly. but if you dont have this option, you still can make the picture by take 3 times, first with EV -1, second EV 0 third EV +1.

the resutl will be like this

+1 EV

0 EV


-1 EV


you see i got 3 picture with 3 different exposure, i use aperture priority mode, with auto braceting. this one of benefit of auto bracketing. we can get 3 picture and we can choose 1 of the best. From this 3 picture i choose the under exposure because its looks better. But for HDR we dont need to choose, we use it all.


there are many HDR software, the most interesting is photomatic, its cool but its not free. photoshop also have the facility in CS3, but i always fail when use it. somebody said you have to make a real good picture with a good camera to make HDR with CS3. so i wont use HDR in CS3 again.


i tried for free software, it named picturenaut, Picturenaut was born in the German photo community.Picturenaut was made to focused on HDR generation from a series of bracketed exposures,tonemapping, and HDR editing. and it increadibly fast software.


instalation : no need to install. Picturenaut has no installer.Unzip the picturenaut ZIP archive with it's path informations into a folder of your choice. Then you can start picturenaut directly. You will find it in the "bin" subfolder.


lets start the work.


first choose file -> generate HDRI



select your pictures by pressing add


after that , your selected file will shown on the list.please choose automatic image alignment



wait for the process, the result will appear soon



dont be please with the result do the tone mapping, choose image-> tone mapping, i like to use Photoreceptor physiology



do the necessary adjustment on tone mapping to make the best image you want



press ok and wait for the result, do the save as process and the result.... will be TIFF. Its large file but you can change it to Jpeg by other software like photosop or picturenaut also provide the converter too, in the bin folder.


the result will be like this, maybe somebody can make it better than this. i already satisfy with the result.

HDR result
