I suppose, seeing as I posted the above test I ought to have a go, just for the hell of it as much as anything..

IR TV remote waved around in front of lens a bit, on tripod, in loo with light off. Highly technical laboratory test situation, as always..

Does this make my bathroom an "Infra Red Light District".. ooer.

Oh, and I went and bought an R72 (cokin A) off ebay after seeing the images in the link above..

Hi,

I just found this..

Quote:
To test to see if your digital camera is suitable [for taking IR images], in a darkened room, switch the camera monitor on and have a TV remote in front of lens. If you see the IR led flash fairly bright when a button is pressed, then your camera has enough sensitivity to IR. If you have a digital SLR, then you will have to take a test shot instead.
Hope that helps,

Cheers

Liam

Oh I knew that..

Personally, I do very little image manipulation after processing the RAW files. I find Silkypix does almost everything I need to do.
Admitedly I've only used it on one set of photos, the sunset ones from last weekend, but 1, I didn't see how I could get the colour saturation that I liked, whereas GIMP gives me much more freedom, and 2, I didn't like the outcome with SPs sharpness controls. I get very good results with GIMPs unsharp mask, and use it on the same setting almost exclusively..

Saying that, I'm definitely not going to give up with SP.. if everyone else gets results, then my guess would be that I'm probably doing it wrong..

I use GIMP with Windows.. and the GIMPshop option is basically a reworked version, that (in theory, as I haven't really used PS) has moved the tool controls around so they should be familiar to PS users.

Hi George,

[A tiny bit of tweaking in Irfanview (let alone anything more sophisticated) would have improved both contrast and focus.

I do everything in GIMP, or GIMPshop.. both free and easy to use, once you know where the tools are. I keep on promising several friends of mine to write a tutorial on it for enhancing photos, as they all have P&Ss, and you're right; it doesn't take much to make a good photo really good, with a bit of knowhow. If I get round to it, I'll post it up here somewhere.

Many won't want to spend money on PS etc, if they've only got a relatively cheap camera. Different matter when you've got a couple of grands worth of gear, you want to get the best out of the photos.. saying that, GIMP does work well with jpegs, but being only capable of working with 8bit images, it's of little use to people who generate tiffs from RAW files. I've seen a few of my jpeg images printed at A4, and I can definitely say that GIMP works..

Cheers

No, that can't be my shot, you must have gone to the same place (Osmaston Park, Derbyshire) and stood in the exact same place and taken a new photo Nicely done :thumbs up:

Hi George..

Look at Liam's cat shot...

But Liam has shown that in the right hands, it can still take acceptable pictures.
I'm flattered George, but they are Accreditors shots. He didn't have a facility for uploading them to the board, so I offered to host them from my website.. all credit goes to Accreditor, and well deserved.

Cheers

Hi Jim,

Hope you don't mind, but I had a little play with one of your images, and I don't think it's worked out too badly. I've de-saturated, added contrast, sharpened it a little and added a little noise to it, to simulate grain.

I did try and get the colour version enhanced, but I couldn't get it just right.. that's more down to my lack of skill than anything else. I guess one of the experts here could easily do it.

I think it works, mainly because B&W is normally looked as an image more than a technical exercise.. and it gets rid of CA.. very easily.

If it's any good, I'll send you the full sized version back of course, as it's your photo.

Cheers

Liam

Hi Tim,

that's 'cos I'm rubbish..

They work now.. I uploaded them to the server with uppercase file extensions for some reason.

Cheers

Hi Accreditor,

I'll post a couple of shots for you. Check your private messages, for details,
