Present smartphone camera takes HDR function oneself, but a lot of people do not know this function takes a picture to us have what profit. As above graph, open mobile phone camera to be able to undertake installing.
HDR namely High Dynamic Range (tall dynamic limits) , what this dynamic limits points to is a photograph go up the brightest with the relative specific value between the dismallest share.
After open HDR function, hand opportunity takes 3 pieces of pictures repeatedly, respectively correspondence is owed expose to the sun, normal exposure and expose to the sun too, synthesize again for a pair of photograph, promote the detail of dark ministry and bright ministry show.
So, when taking a picture below HDR open condition, press won't be become instantly after shutter picture, need to wait a little while however.
But, be not say open HDR can take any pictures more beautifully, this also is to need particular case of concrete analysis.
?
? We observe above two pieces of photographs, discover not hard, after open HDR, be patted the sun by the condition of cloud layer keep out, and stand by ground part to appear very bright.
Will see these two pieces of pictures again, these two pieces of pictures are taken in day of an overcast and rainy. After open HDR function, of the celestial dusky that pats, but ground part still very bright.
Such, we can analyse conclude:
What setting suits open HDR?
1, when patting the scenery outdoor to illuminate, the tremendous contrast between OK and narrow nature and ground.
2, when taking sunshine servent matter, can remove the disharmonious factor such as dazzle light and shadow.
3, weak light and be in a poor light when setting, can increase the brightness of foreground. .
What circumstance falls not to suit open HDR?
1, when patting mobile, because need to pat 3 pieces of hand-in-hand travel to synthesize repeatedly, synthetic picture can appear double image phenomenon.
2, fall in tall contrast setting, film technically for instance when shadow or inverted image, the contrast that can drop objective and empty movie is solid, photograph effect will sell at a discount greatly.
3, fall in colourful setting, can bring about degree of saturation to reduce, for instance, when the sky that needs outstanding La La, need not brightness of part of attend to ground.
Good, introduce here about HDR. Of course, want to take more beautiful picture, still need to master other a few little skill, touch shooting angle of screen focusing, choice to wait for instance.
