試玩彩色紅外(#21 Jun22 update)
本帖最後由 bubu 於 2015-6-22 12:37 編輯月前將部雞肋機Ricoh GXR交alexty2師兄改720nm紅外。
用GXR改只是改個A12 mount嘅sensor。只要買多個A12就可以拍翻正常彩色, 够flexible.
後製工夫比較多, 亦要累積經驗先出到想要效果。有排學/玩!
最吸引係拍完入Photoshop前, 都唔知張相會係點。{:4_107:}
先試Cosina 15mm f/4.5 @f8。Crop左變22.5, 都算夠wide拍景。
再試Nikkor-O 55mm f/1.2開盡影close-up, 睇下紅外bokeh係點。 wa! an area I have never tried! looks pretty fun raumplan 發表於 2015-6-12 23:09

Yes, it is really fun playing with all those colour tools in Photoshop to create the tones you want! I should have given you some colour correction filters to try. 又幾過癮喎！！！ :loveliness: Wawawa!
I heard if you want to get colours like using infrared film (and get pink leaves, etc.) you need to invert color channels.18x24 c-hing is the undisputed expert here. vincecharus 發表於 2015-6-13 01:08

Yes, 18x24 ching is the expert and that's his post stimulates me to try colour IR.
I did play around the Colour Temperature settings in Camera Raw, then twisted Channel Mixer with some touch on Hue and Saturation to get a pink leaves shot like this: Wow, amazing shots !

終於踏出第一步，一步步來。好玩乎？
由於近紅外綫波長不同（約600-720ηm），會產生不同效果，後製（很費時）亦有少許分別。
不過，後製方法滿意時，即可將數據儲為 "profile"，以後則方便得多。
very interesting, love the flower shots and bokeh {:5_259:}{:5_259:}
my GXR has a mission (impossible??) very impressive and interesting! Yeah, should also add color correction filter to try out different effect!!! {:4_134:}
Haven't tried IR for quite some time lei...It's way to troublesome to focus on a M without live view... 點評
