Frankly I'm jealous of the photographers who have an infrared camera modifications. While although I have a Hoya infrared filter, but the result does not really come what I had in mind. My camera is Canon 400D. Someone said that this camera is not suitable for IR photography with a filter.
Various problems encountered.
- Deep black filter that makes the ability to focus is lost. The idea is to set the focus first and then attach the filter.
- Darkness makes the camera needs a long exposure to achieve Ev 0 so then I would need a tripod. Don't try to shoot a moving subject like human with these tools. You'll get a ghostly picture unless this is what you want.
- The resulting image is really like a flood of red. And I do not know how to edit it with photoshop. Some said I should turn the red channel to blue and blue to red. Didn't work with my 'flooded red' picture.
Conclusion, My camera cannot be paired with this filter. But I do not give up so easily. After looking at various websites I finally found myself a simple and suitable formula. A Tutorial for Simple IR Editing.
This technique comes only with four steps:
1. Choose a photo with lots of green plants. For IR images of green plants will turn into white (for B/W Infrared) or somewhat pinky brown. For my formula, I choose the latter.
2. Use photoshop, I use Adobe Photoshop CS3. Rather old but still powerful.
3. Choose Channel Mixer.
4. Go to Channel Mixer - Output Channel - Green. From Green, slide the Red to 50%, Green to 0% and Blue to 50%.
5. Done! You have finished simple IR. Easy isn'it? There's more? Yes, of course. But it will come on the next post. A Tutorial for Advanced IR Editing.
