Refining my processing of digital IR images

Got a thin skin? Then look elsewhere. Post a link to an image that you've made, and invite others to offer their critiques. Honesty is encouraged, but please be positive in your constructive criticism. Flaming and just plain nastiness will not be tolerated. Please note that this is not an area for you to showcase your images, nor is this a place for you to show-off where you have been. This is an area for you to post images so that you may share with us a technique that you have mastered, or are trying to master. Typically, no more than about four images should be posted in any one post or thread, and the maximum size of any side of any image should not exceed 950 px.

Forum rules
Please note that image critiquing is a matter of give and take: if you post images for critique, and you then expect to receive criticism, then it is also reasonable, fair and appropriate that, in return, you post your critique of the images of other members here as a matter of courtesy. So please do offer your critique of the images of others; your opinion is important, and will help everyone here enjoy their visit to far greater extent.

Also please note that, unless you state something to the contrary, other members might attempt to repost your image with their own post processing applied. We see this as an acceptable form of critique, but should you prefer that others not modify your work, this is perfectly ok, and you should state this, either within your post, or within your signature.

Images posted here should conform with the general forum guidelines. Image sizes should not exceed 950 pixels along the largest side (height or width) and typically no more than four images per post or thread.

Please also ensure that you have a meaningful location included in your profile. Please refer to the FAQ for details of what "meaningful" is.

Refining my processing of digital IR images

Postby DaveB on Mon Dec 04, 2006 11:25 pm

Recently I've been working on some new software to extract as much detail as possible from my digital IR images. Tonight my prototype finally began doing things I'm happy to show people, so please excuse me while I show off! :D

For a while I've been using a Canon PowerShot Pro1/87C (modified for IR) as my main infrared camera. Like most compact digicams this 8 Mp camera has a small sensor, and is not known for having low noise.

You may have seen this image from the recent Melbourne Portraiture workshop. This is the image processed using the normal tools of Photoshop/Noise Ninja:

I've re-processed the image using my new software (which reads directly from the DNG files):

The tonality is slightly different: I'm still working on this.

Here are 100% crops (unsharpened):

Again the tonality is different, but I've been aiming for images with less noise/grain and more fine detail.
What do you think?

Definitely bring out more detail, you can see almost every pore on her face. The process looks to be doing the trick, but this isn't the kind of shot where I'd personally want this sort of detail.. and I realise your only using it as an example just wanted to say it... I don't find it flattering to the lovely model.

Dave that's a decided improvement and a result to be happy with. Did you write the software yourself?
