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.

Thank you everybody,
I used the Hoya R72. What I found is that the pictures have to be on the underexposed side to get some blue in the sky after mixing the channels.
Cheers,
Gerard

Very nice image Gerard. I love this type of IR photography.

I have never really understood it though. I know that you don't just put the filter on and get shots like this out of the camera. What type of PP do you have to do in order to produce things like this? How much does an R72 IR filter cost?

Sorry for all the questions, it's just that I'm keen to try something like this but haven't the first clue where to start.

Cheers

Hi Gerard

This is a very dynamic scene, there is alot going on, although your use of the IR filter on a scene like this works extremely well.
How did you channel mix a red image to look black and white while maintaining blue the tones?

When i post process IR images i only know how to convert them to greyscale for best effect.

Probably the 67mm Birdy, for the kit lens. Looks like they start getting quite expensive.

I say over $150.00, am not sure, and I HATE this type of IR.
Why? I have been using the night vision goggle on my flight helmet for many years once I was in the military, not now and never will.

Great shot Gerard, I love IR stuff.

rokkstar, my R72 67mm for the kit lens cost about $70-$80 I think.

Rokkstar,
I paid $164 for the 72mm.
Wendellt-Rokkstar,
I picked up a few tips from a thread on dpreview. From memory, it goes like this (that's what I've done):
-WB: set wb on preset on measure on a piece of green grass. (No green grass as you would know, so I used a green bag from Aldi...about the same colour as Woolies and so on)
-Remove filter.
-Compose and manual focus.
-Put filter back on. (Obviously the camera is on a tripod)
-Shoot (Underexposed seems to work better)
PP
-Open in PS
-Auto levels
-Into channel mixer:red channel=red 0% / blue=100%
blue channel= red100% / blue0%
-Into saturation:red= -100
magenta= -1005
That's it!
You can play around with the settings in the channel mixer and so on...
Thank you for all the kind comments,
Cheers,
Gerard
