colinbm Posted May 25, 2015 Share Posted May 25, 2015 Neat work Andrea, you have done this flower justice.Could you crank up the contrast a bit more in the IR photo ?There seems to be lots of hidden details in there ?CheersCol Link to comment
Andrea B. Posted May 26, 2015 Author Share Posted May 26, 2015 I'm not sure it does much good to push contrast? IR is inherently soft and we can't bring out detail which isn't there. About all we can do is use the Photo Ninja detail (clarity) slider to increase "local" contrast. I already seem to have already pushed that a bit too far making the preceding photo have a bit of that "clarity overkill" look. (Note the beginning of haloes.) When I pushed overall contrast a bit more in this attached foto, then things begins to blow out. Link to comment
colinbm Posted May 27, 2015 Share Posted May 27, 2015 Thanks for showing me this Andrea.Col Link to comment
Andrea B. Posted May 27, 2015 Author Share Posted May 27, 2015 I can't decide now which one I like better (except for the halos). :D Link to comment
nfoto Posted May 27, 2015 Share Posted May 27, 2015 Digital IR is almost always soft in terms of contrast, and often also in sharpness. You need massive sharpening and forget the artefacts - they become part of the visual expression :D I sometimes process the RAW IR file in two conversion programmes, of which PhotoNinja is one and the other might be ASP or ACR, and build a composite of the two files. Can help to combine sharpness (PhotoNinja 'clarity') and colour and/or contrast (other converter). Link to comment
Alaun Posted May 27, 2015 Share Posted May 27, 2015 Andrea you might try this, if you have PS: In PS try this one: Layer > New adjustment Layer > Levels <OK> Then on the upper right corner of the properties window of the filter click the options button = and choose Auto Color Correction Options and click Enhance Per Channel Contrast <OK> done Link to comment
