HDR Skies: Beautiful Time-Lapse Film of the French Countryside

French pho­tog­ra­ph­er Tan­guy Lou­vi­gny cre­at­ed this time-lapse film of bucol­ic Nor­mandy and Brit­tany using High Dynam­ic Range (HDR) imag­ing tech­niques.

From for­est floor to set­ting sun, Lou­vi­gny’s shots ren­der fine detail across an extreme­ly wide range of lumi­nos­i­ty. To achieve this he used the auto-brack­et­ing fea­ture of his Canon EOS 400D and 60D cam­eras to cre­ate three dif­fer­ent expo­sures for each frame in the film. (At 30 frames per sec­ond, that’s 90 expo­sures for each sec­ond of screen time.) Lou­vi­gny then merged each set of three expo­sures into one image using Pho­toma­trix Pro 4.0 soft­ware, selec­tive­ly tone map­ping each sequence to hold detail in some areas while allow­ing oth­ers to go dark.

To cre­ate the mov­ing-cam­era effects, Lou­vi­gny designed and built his own robot­ic three-axis motion sys­tem using Tetrix motors and a LEGO Mind­storms con­trol sys­tem, which he pro­grammed in ROBOTC lan­guage. This allowed him to auto­mate the tor­toise-like dol­ly, pan and tilt move­ments. Lou­vi­gny edit­ed the dig­i­tal film in Adobe Pre­miere and After Effects soft­ware. To top it off he com­posed his own music on a Roland MC-808 groove­box. For more infor­ma­tion, go to the pho­tog­ra­pher’s web­site and Vimeo page.
