Hi All

I have been experimenting recently with IR filters, and had one of John B's mounted on my kit 14-42mm lens (shots = Purton Boat Hulks thread). However, I needed one for my Oly 11-22mm lens and have been looking around for some time for a good deal. They are particularly expensive for the 72mm fitting required for the 11-22mm, so when I spotted one for sale for £16, from China... I thought this was worth a punt and ordered one.

I must say, that this is £16 well spent in comparison to what would have been over £100 for a non imported one.

Here's the link if anyone else is interested in purchasing one of the imported ones: http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=170335790296

I can thoroughly recommend them. My lens took just a week to arrive after I ordered it, and I am happy with the performance too. I am no IR expert, far from it, but I do like the effects from this filter.

Here's a few samples:

You're welcome Edward, no problem.

Remember though, I am no expert here, and especially in IR photography, but I must say I rather do like the effect of this filter. It seems to suit my current génre of landscape/seascape shots, as well as my PP style.

I use full 'Manual' mode a lot more now, and used 'M' for these shots too. The exposure differs on different cameras (for the same settings), and on my E-3 I find that apertures between f8 to f13, and speeds from 10s to 30 s are the way to go... hence the cloud movement.

Don't forget to show us your shots when you have some.

I too no nothing about IR, but it will be fun to learn a new trick! I will let you know when I have got hold of a filter & post some photo`s here for you to see *yes

John, thanks for the posting.
This filter looks impressive, I like the first one best.

I take it that you did not modify your camera ?

It will be on my list for when I am back in Holland again in 2 weeks.
By the way, this seller has the same filter in 58mm too.

You're welcome Peter.

No, I haven't modified the camera, just used a filter on the lenses. I am considering finding out if my E400 could be modified... but the tones of that Kodak sensor are possibly too lurvely to mess with!

That is what I was hoping for: no mod's to the camera.
Otherwise IR would become expensive to me after all: I don't want to mess with my E410.

Greetings,

John, Just a couple of questions I`ve thought of:
1. Will the camera auto focus through this filter, or can you only focus manually?
2. Do you shoot with the camera set to record colour or mono?........:confused:

Hi Edward

John, Just a couple of questions I`ve thought of:
1. Will the camera auto focus through this filter, or can you only focus manually?

No, there's not enough ambient light getting through for the camera to focus. I set mine on manual focus.

The ideal solution is to put everything to manual, then set up and compose your shot prior to placing the IR filter on the lens. Place the IR filter on the lens and then take your shot. I usually ensure the lens is focussed on infinity, and from then tend to use the 'best guess' technique :)

2. Do you shoot with the camera set to record colour or mono?........:confused:

I shoot all my shots in RAW, and in colour. I believe that if you shoot in B&W, that the RAW data is still in colour, so even if you shoot in B&W it makes no real difference if you shoot in RAW.

Hope that helps.

Thanks for posting these John, I am thinking about having my E1 converted to a dedicated IR shooter but that will cost well over £200:eek: The benefit being that you are able to use the camera as you would normally as there is no loss of vision i.e. no heavey filter on the lens.

However for £16 or so that's food for thought...........

theMusicMan
29th August 2009, 08:20 PM
WOW, £200 for a IR conversion, that seems very expensive to me Neil. I have to say though, I do like the thought of an IR cam!! :)

IR is much easier with a dedicated cam, however the cost can be a bit much for a hobbyist, I believe prices start at around £250 plus vat although I've yet to get a firm quote for an E1 conversion, more info can be obtained from www.advancedcameraservices.co.uk

As with a lot of these things, I guess it depends how serious you are about IR Photography.

It's a good job us photographers have deep pockets:rolleyes:

Too true Neil, too true indeed. I must find out how much an IR conversion for my E400 would be before I totally dismiss the idea.

Here's another one taken with the el cheapo Chinese IR720 filter. Taken today on the E-3 with the 11-22mm on board.

Very impresive, John !

Even whithout the modification one can make exiting photo's......

Congrad's on the results.

I really like that shot of Tintern Abbey, very good.

I also just bought one of those cheap eBay IR filters 72mm size £14. Certainly does the job alright. So far I just had a brief go with it as its not been sunny enough to do more.

I set the camera (E-3) in manual, ISO100 f/8 about 10 seconds exposure (sunny scene) seems about right. I shoot raw+MF and set the camera for B&W JPEG 'orange filter' that way I can see in live view how its going to come out. Live view boost on.

Black and white results seem good, but so far far I haven't been able to make a faux-colour image in PP. Not sure if its practical with this filter.

Have you tried using Lightroom Alistair...? I have saved a few presets based on my IR images that seem to work fairly well. It's hit and miss though and I find I need to adjust the develop settings for each image.

Thanks Edward... not so much opportunity to get out and about with the kit over these last few weeks. We're off up to the Brecon Beacons in a week or so, so hopefully I'll use the IR filter then.*chr

Hi

yes I have LR and I also use gimp. I was trying for the effect where you adjust the WB then swap the red and blue colour channels for the faux blue sky. But I'm not sure this is possible with this filter. Still I really like the strong B&W look and with the long exposure effect it makes for a really nice image (at least it can the right hands).

I got some more shots with it at lunchtime today, will process and post one or two this weekend hopefully.

Which IR filter did you opt for - 680, 720, 760 or 950nm?

I have just ordered one, only 46mm dia so quite cheap and I decided on the 720nm.

For once my camera's notoriously high IR sensitivity is going to be a benefit. I look forward to seeing the results, may post them on DPNow if they are interesting.

Here are some shots I got in at lunchtime today, not that they are anything special, but as far as I can tell this cheap 720nm filter does the job perfectly well *chr

This last one has the faux-colour effect I was looking for, despite the weak sunshine, so I am well pleased. GO AND GET ONE OF THESE FILTERS! :)

Does anyone use Cokin IR filters? or do you all use screw-on ones?

I believe that if you shoot in B&W, that the RAW data is still in colour

It's the opposite really!

The sensor photosites only register light levels, not wavelengths, which means that raw data is greyscale. It only get interpreted as colour in the subsequent de-mosaicing process - either when being converted to JPEG in the camera, or by a raw developer program.

e.g. The conversion process 'knows' that the mid-grey that the first photosite registered was taken through a green filter, and is therefore interpreted as mid-green.


BTW, raw is not an acronym and therefore shouldn't be capitalised. It just means what it says - raw. JPEG _is_ an acronym and therefore should be capitalised


I fancy getting one of these filters, but the Ebay link no longer works. What's the I.D. of the Ebay seller, please.

What's the difference between using one of these filters and changing the settings on your camera to shoot in black & white?

You do shoot some cracking beachscapes. When things warm up and I have a bit more time, I intend to get out and play with my welding glass 13.3 stop ND filter.

Cost wise at a few quid plus a cheapo "Cokin P-type"-type adapter attached with gaffer tape it is as cheap as it gets. You have to remove the green tint in PP in the same way you have to remove the purple tint from an IR filter.

The IR filter gives a unique effect particularly with landscapes, trees especially, but just thinking in terms of using it as a simple ND filter how many stops do you think it equates to? At that price and for the convenience of being able to screw it to the front of your lens (a disadvantage of the fairly weighty welding glass) it is a possible alternative?

Might be a stepping stone between ND8 and the welding glass ;)

cheers

Hi David

Thanks for your comments, I got it lucky with the weather that day to be honest, it was the same day that I managed to get the shot that I entered in the Photo of the Year challenge. A storm had just passed over, and it left things looking lovely.

I usually play around with the exposure when the 11-22mm has the IR filter screwed in... and as far as I remember, I tend to use exposures between 10s and 30s, with apertures from f4 to around f11. I'd say it comes very close to being a 10 stopper to be honest. That's going to be my next purchase, the ND110 72mm filter... just gotta get one as summer approaches...:)

I tried the welding glass, but I must have a bad one as there are lots of scratches and glitches in the images taken.
