@lord,sir bumile ako ng Ir filter para sa 18-105 lens nag try akong mag picture ng outdoor ng 60-180sec pero red paren ang buong picture.may suggestion ba kayo para lumabas yung kulay nya na hindi lang puro red yung buong screen?
you should start with correct white balance prior to shooting and postprocessing. kapag off ang white balance sa start palang, hindi mo maattain ang flexible tonal range ng IR. i use custom white balance. i do it by shooting and filling the frame with leaves, pwedeng grasses or leaves ng tree. basta dapat atleast 90% of the frame leaves. initially set to auto white balance. shoot with the IR filter screwed on the lens. f/11, iso 200, approx 60-120 secs when the sun is overhead. i shoot 10am-3pm. after shooting the leaves, set your cam to custom white balance. use the leaves photo as your custom white balance. then shoot using the custom white balance. stick to f/11, manual mode, 60-120 secs. it really depends. shoot in RAW format
post processing
Canon DPP software or camera raw
-convert your image to TIFF 16 bit
Photoshop
open the image
image>adjustments>auto levels
layer>new adjustment layer>channel mixer
channel mixer
-output channel RED: red from 100% to 0, blue from 0 to 100%
-output channel BLUE: red from 0 to 100%, blue from 100% to 0 or less.
-click ok
-minor adjustments on levels, contrast, curves and saturation. (it depends on your taste)
blue sky and yellow leaves.
cheers and enjoy
