Just had the XE1 converted to IR. As soon as the sun comes out i will see if the cost was worth it.

The weight saving over the D200+17-35 is considerable. In fact, the XE .(IR) and the XT (colour) with 2 lenses (18-55, 55-200) combined are about the same as the D200 and lens. So i can get them all, plus the wifes video, in one bag....and still carry it!

Wheres that sun?

o.O

Cool.
Look forward to seeing some results.
Here comes the sun!

Did a custome wb off the grass today when sun was out. Quite a lot different to the setting ACS had. (maybe they didn't do one!)

I took a few shots in the garden using the 55-200. I haven't downloaded and assessed them but they looked really sharp on the LCD...though I think I could see a hotspot.

Think I need to dig out the old Action to autocorrect it :sssshh:

I think you will find a hotspot with both zooms but they are Photoshop removable! The 14mm, 18mm, or 35mm lens are all very good in IR with no hotspot.

Off on our travels shortly, so no time to do anything now. But i may treat myself to the 14mm next month if the ir looks promising. It would be useful for colour as well....18mm being really 25mm is sometimes too narrow.

Have sold 3 nikon lenses to fund XT purchase....but i feel a further purge of nikon gear imminent ....if it all performs well.

Not happy with the 18-55 for IR...nasty hotspot. The 55-200 is ok, but sadly not wide enough. Will need to evaluate the 14mm when I return home.

Jonathan, It's interesting that you said the hotspot wasnt too bad using the external filter. Clearly putting the filter inside is exacerbating this effect.

A 720nm shouldn't effect your exposure very much and it may reduce the hotspot.

Eric-

Thanks for the timely posting... I was just about to list my xe1 on ebay. I've dithered about it since it is worth so little in the aftermarket.

I'm going to look into an IR conversion...great idea !!!

thanks

Tom

Be interested to see one of your images.
If you want to Dropbox a RAF then I can compare.

I forgot why I stall out each time I go to get a camera converted... What the heck is the deal with all the different types of conversions?

What did you get for the ex1? I'm thinking R72/89B IR filter installation (720nm) from SpencersCamera.com for $250???

Does that make sense. They offer 5 different conversions !!!

Thanks,

Tom

Mine was the 720nm.
I find it gives a cleaner, more 'duotone' effect of white and brown.

Some of the other filters introduce reds and purples which can give weird effects (IMHO) when post processing.

It's sort of akin to tinting a black and white print ...compared to tinting a colour print. With only mono to work with you get a purer result. Tint a colour print and everything is unpredictable.

Just my 2cents.

Have to say its quite horrendous!
I have been having to very carefully frame shots with a view to ease of removing the hotspots later!!

I will see if I can do a comparison shot later today when sun comes out... with both lenses at 55mm and upload to my Dropbox.

I haven't got the raw converter with me ...so if you would like to grab these images, process and post them here to demonstrate the extent of the issue, that would be ok with me.

Will send you the Dropbox link when it's done.

I fancy getting my XE1 or XPro1 converted to IR .
The XPro1 is favourite as I like the EVF on the XE1 better.

Just as a heads up on the choice of lens....

I have the 18-55 and 55-200.

Firstly for landscapes 18mm, =24mm, isnt quite wide enough for wide landscapes that make IR work so well. (that isn't to say you can't work tighter with IR, I've done some interesting close ups)

Working with the 18-55 I have discovered it has the potential for a nasty hotspot. Initially I thought it was a total right off but on further investigation it's clear that the wider the focal length AND the smaller the aperture, the worse the hotspot shows.

For example ...at 18mm and f8 the hotspot is bad...at f16 it's like a spotlight down the centre of the lens!!

I have deduced that from 18-34mm you must work at no more than 2stops down from max aperture. From3 35-55 its a more generous 3-4stops.

This explains why the 55-200 is acceptable at f8 (my preferred aperture for IR)

All this means is that unless I use f4 I can't use the 18-34mm range. But as I said earlier, this is already not wide enough at 18mm.

So when I get back from Italy, I must check the 14mm prime to see whether it too, has a hotspot. If its ok, then I will use it on the IR (still there for colour use of course). If its no better, I need to rethink the usefulness of this exercise.

It's really cool having a lightweight kit for both colour and IR. I have been clambering round a medieval town in Umbria the last two days and the backpack has been barely noticeable. But if I have to spend hours correcting image defects in photoshop ...it's going to become a point of irritation, and lose its appeal!

Fingers crossed the 14mm is ok.

Edit...can I just add that there is a reason for using f8 with IR. You get a sufficient depth of field to ensure compensation for the focus shift due to IR. Of course the camera has, or should have, been recalibrated but it's still a bit of a black art...imho

The exposure shown is a normal exposure for IR under bright sunny conditions here in Spain.
If this was UK light it would be around 5-10 seconds at f2.8 at ISO3200.

And now a little bit of processing.

Adjusted exposure by +2.3EV  (seems a lot).
Converted to B&W
Sharpened

Post processing is nothing more than a convert to B&W and sharpen in Lightroom.

Eric, definitely no hotspot!!

Taken with XE1 rather than XPro1, again with Hoya R72 filter.
2.5secs, f8 at ISO200

You're scaring me again :-)

I rarely use the fuji zoom... Part of the value to me is the wholly different concept of size, weight and prime!

I think I'll go ahead...the old xe1 isn't really worth much right now - it plummeted with the intro of xe2 and this is about the cheapest way to give IR a spin around the block.

But I will wait with baited breath to hear your thoughts on the 14mm

Frankly Jonathan I wouldn't expect a hotspot from using a front mounted filter. It this were the case there would have been an outcry from the many people who use front filters of all sorts.

This is down to the way the internal filter behaves with closer proximity to the rear of the lens and the sensor.

I don't pretend to be able to explain why.

But I do remember that the 50mm f1.8 AND 1.4 primes can exhibit hotspots working normally without filters in colour mode!

I shot some black boots against white background some years back now, and got a blue fog hotspot on the boots. It was very small thought it was a boot defect but as it was catalogue work and I noticed all the boots with the same mark. Changed to the 105mm lens and the marks disappeared!

Its not until you do repetitive shots from same position and lighting that these sort of issues show up.

I have some time on my hands now so I will turn the files to jpg format on the XE and take some example shots......be prepared to be horrified!

Initial look the hotspot is nasty as it is dual when you get to f8 and beyond.

Yes. I found that quite intriquing. Why 2?

It must tell us something about HOW it's caused.

Is it the curvature of the rear glass?

I've posted some IR images taken recently with the Fuji XE1, in my gallery.

To over come the hotspot on some I had to shoot a panorama series, thus moving the central hotspot in each image off centre, and then overlaying the images so that the hotspots were covered by the next image.

They are sepia tinted 'normally' illuminated in the viewfinder.

Without a white balance correction (ie making a custom white balance from green foliage) the image is red...but not dark red.

I always shoot some grass in full sun and save the wb as default. The colour temperature varies a bit around the year, but as long as I don't do it in low autumn light or late in the day, the wb is usually good enough.

Eric, So some of the IR images from your holiday are not at all badly effected by the hotspot. ;-)

What are your thoughts on the use of the IR converted XE1 ?
Is it as good or better than the D200?

I think that you need to test with a Fuji 14mm .

The XE is a very good performer and a definite lightweight alternative to the D200. It really all boils down to the lens.

If the 14mm has no hotspot (on a converted camera) then it at least gives me a wide landscape option. BUT...with the 18-55 performing so poorly it leaves a big gap in the focal length range.

With the D200 I use the 17-35 ( 25-53mm equiv) almost exclusively.

I've never felt the lack of a wider or longer lens!

I am loathed to ADD more lenses to the Fuji range, as the whole point of this change is reducing weight and complexity when travelling.

I need to go back through my IR images and establish the percentage shot at each focal length. It may give me a steer towards where to go.

But there is no doubt I need to take the XE over to WEX and try all Fuji X lenses for hot spots before committing more cash. Wouldn't it be great if the humble 16-50 (24-75) didn't have a hotspot?

Maybe next week when I have my new vehicle.

Looks like you need to test the 14mm and 35mm primes.
I have 14, 18, 35, 56, 60, 18-55, 55-200 lenses. I will come to UK in September and you can have a test then if you dont get to Wex before!

I just noticed that you said in your post#35 that the IR gallery images were from XT1.
That means you used an R72 on the lens.

Is that correct or did you mean XE1?

I dont think the 18mm is that wide after the 14mm.

Also I didnt say that I also had the Samyang 8mm in Fuji X fit. Manual focus only but with it being so wide it is easy to focus and use f8 and hyperfocal infinity and 3m all in focus.

If you test the 18mm and want it then you can have my one Mint condition. Maybe even swap for your D200 IR. PM me if you are interested.

I just noticed that you said in your post#35 that the IR gallery images were from XT1.
That means you used an R72 on the lens.

Is that correct or did you mean XE1?

Sorry Jonathan, missed this post....typo.... should be XE 1. Can you correct it, so as not to confuse anyone else?

Well I would be very pleased with those new images but then again I dont have your IR post processing skills. Mine never have the sky colour and rendering that you achieve. :-(

It's really not that involved.

I set the white and black point using Levels.
I then use an action that 'sharpens' by increasing contrast.
At this point I either bin the image for lying about its potential or look at extraneous colour.....

Firstly remove all unwanted colour. Ideally I like to only have yellows and maybe some reds in the image. So I go to Hue Sat and INCREASE THE LIGHTNESS of all the channels except yellow and red. (Don't desaturated as it makes those areas go grey.)

With a narrower band of colours available you get a purer flip eg just yellows to blues.

So if the image recommends a specific treatment eg blue sky, brown road...I create a second layer and do the channel mix swop on the blue and red channels.

Then erase the areas on the blue top layer to reveal the brown bottom layer parts.

After flattening the layers I go to Hue Sat and whack the saturation to maximum. This shows any areas in the image that may have retained spurious colour casts. Then after cancelling this change I just use the sponge tool to desat those spurious color areas AND THEN use the dodge tool on the same areas to lighten them (same reason as the earlier comment).

For me it's all about getting the whites white, the blacks black and leaving colour in areas that recommend it.

But the biggest step is only taking images that have a strong non IR interest factor. Too much shrubbery, grass or trees just swamps the eye...whether green or white.

;-)

I've added another 6 images to the gallery for those interested, which hopefully show the good side of the Fuji XE1 (as opposed to some X series lenses hotspots).

Most of these have had the hotspot masked or diminished.

Having already briefed Mr Knights on this subject I thought I had better share this snippet with other potential Fuji IR users.

As mentioned already, the 18-55 has a severe hotspot throughout the widest part of its range rendering it useless for IR.

Today I discovered the 10-24 ALSO has a severe hotspot...but throughout is range (not surpringinly continuing the effect seen in wider end of the 18-55 lens)

The 14mm prime DOESN'T have a hotspot as JK discovered.

But the cheapo 16-50 'kit' lens ALSO DOESN'T have a hotspot...at least not up to f8. Beyond f8 there is a faint central fog which may be undiscernable to many eyes, and easily adjusted if required.

So I got oneof these lenses at a good knock down price and will publish some shots with it in due course.


It's interesting that the problem occurs in the 'quality' wide zooms but not the cheap ones, longer zooms or primes?

Obviously to do with lens construction, but what exactly, can't say.

o.O

I look forward to seeing the IR results from your XE1 with the 16-50.

Well done on the cheap lens acquisition. Looks like you have made a good find and purchase.


BTW:  It is Dr Knights!!!
 :devil:
