ELP Filter

[AuntieHuat]

Hi,

I am using a Canon S1 IS. I am currently using a Hoya R72 and it seems I can only produce monochrome images. Also, my images are not defined even when I use a tripod. Typically I use about ISO 100 , 6-8 seconds exposure , custom white balance using blue sky. Some even seem blur-ish unlike the photos I see in this forum.

I have read that using a ELP filter might help me produce coloured IR photos. I would like to ask if anyone knows where to get it and how much it would cost?

My filter size is 52mm.

Thanks in advance
Kelvin

ELP filters are not available in shops locally, you have to order.

Here's a link to a previous thread where loupangrou did a MO for it. This thread also contains info/specs and price for the ELP.

Hi AuntieHuat,

Have you tried taking any IR with the R72 at a higher ISO ? say 400 ?

Can you post a result for us to see ?

Cheers

Hi Teerex,

Guessed a missed a chance to purchase the longpass filter then. By the way, do you know what the diameters 3" and 4" X 5" mean? Are they not screw type filters like my 52mm?

Thanks

Hi Pablo,

So far the highest ISO I used is 100. I try to keep it low as I have the impression that IR photos require long exposures. So using lower ISO allow me to shoot longer shutter time without overexposing the shot. Most of my photos are 8-15seconds exposures. Also, I thought lower ISO have less noise?

I do not know how to attach photos here but I have uploaded them to my gallery along with the specs I used to shoot them.

It will be nice if you can point out anyway I can improve on the quality. I notice tiny black spots on the pictures and it is grainy. Is it noise? The foliage I notice are not well defined. Just a white mess.

Thanks.

Hi AuntieHuat,

The ELP filters are unmounted plastic filters, to use them, you can either hold it infront of the lens, use the cokin adapters or ask a optical shop to grind it down to the filter ring size. Or you can try Dennis's method, he'd glued it to a 77mm filter ring

BTW, see here for instructions on posting images

AuntieHuat,

Took a look at your IR shots in the gallery, looks like most of them have the midtones blown. That's the reason why you get your foliage a white mass.

Try adjusting your shutter tiime if you shot them at manual. Or try correcting them with a little post editing. But no matter how much post editing is done, it will not improve much if the original is not properly shot.

Pablo, PandaOng are Canon users they may be able to advice.

Ark's link should be able to help you post pictures. Still have problems after reading it, give us a "YELL".

Here's one of your shots with blown midtones


I tried some post editing on it.

Test posting a photo to thread. My attempt to create IR colour using a colour and an IR photo merged together. Look eerie according to my sister. Not what I wanted

Hi Teerex,

Thanks.. think the photo looks nicer after your editing. Looks like there is a tinge of colour in it. May I know the steps you used to edit it?

Also, I don't really understand what you mean by midtones blown. Don't quite understand many photographic terms.

Never mind I go do some reading on net first. If really don't understand then bother you again.

If you look at the histogram of you posted picture, you will see that the middle of the curves very high, this means it;s over exposed.

It would be good to try learn to read histogram (I'm learning to), as it tells you about the exposure of a picture. Do a search on the internet, there are many explanationss to reading histograms.

I reduced the highlights (brought down the brightness of the very bright portion) of your picture, adjusted the contrast and sharpened it a little.

Just ask if you want to know anything, I don't know much but hope that can be of help.
