Infra Red Filter Use

I've shot hundreds of IR images, starting with a 720nm filter on my Fuji X100s and later having it converted to an IR camera.  Unfortunately, I have had no success with my new Fuji X100F; it seems the sensor is not sensitive as the old X100s model.

 

I would start by setting a custom WB using a gray card.  If you don't plan to ever look at IR color, it is not as important.

 

Anyway, I never shoot RAW so I can't help you there.  I always shoot color and then go to edit.  I use a simple editing program that comes with Windows Live Photo Gallery but the idea is the same whatever you use.

 

I make a copy of each image and convert one of the pair to B&W.  On each image, I adjust the curves and that does a lot.  I find boosting brightness and/or boosting contrast helps with many images, especially B&W.

 

On color IR, I always adjust the color.  Starting with the initial color set with the custom WB and gray scale, I pull the tint slider to the left and get less red/orange.  I also often lower the saturation.  You can also channel swap in Photoshop but I find I like the look with my current camera without channel swaping although I did it in earlier photos.  You can Google channel swapping IR for more, I would think.

 

I have 366 photos and counting in my Flicker Infrared album.  https://www.flickr.com/photos/97423979@N00/albums/72157649764779698/page1

Page 4 has lots of my newest photos.

 

There is lots of more detailed help on the web but this may help get you started.

      X-s10 Fast shutting 20/30 fps crop ES

      By mapoett · Posted

      Hello. Thankyou,now Is all more clear: I have take some time in your link. Let tell you. I has totaly forget this machine have "compress picture option" and not Only "compress lossless" anyway not change the experiment. RAW  and this last two format look like same result about Number of recording picture. Can tell all results in this: in raw you can make 17 pictures for second. Is wrong. Is about One single Press and wait buffer. Full 30/20/10/8 not change. After 17 Need Press again. You not can Press before "redgreen light recording Is on".   With preshot you can have 25  are more 7 pictures . The story change Only in jpg shot only. In jpg at 30 you have 30 picture but redgreen light off very Fast so you can shot very quicly. At 20 shot Is about start look like infinite shot. 60. So the best performance are this last One  about Speed and recording picture after camera working witout big limit. I want take a shot about Italy cyclet Just for passion. I think i Will use this last setting.  After Need check when battery not are full change and ambient temp.  Anyway my cam look like exactly specific about you link. Im Happy my cam working perfectly.

      Hello from Iowa

      I do not use Flickr, so I do not know what their BB code is. All I did was copy the second link you provided, (starting at https: and ending at  _k.jpg — leave off the [img] and [/img] tags) and pasted it into the message. After a moment, a message popped up asking if I wanted to paste it as the image or as a plain link. I did this twice, the first time I had it paste in as the image and the second time as a link. Nothing fancy or tricky.

      So do I just copy the BB code from flickr and paste it anywhere on the page like other forums or is there some other trick I need to perform to get it to post?

      X Raw Studio Doesn't Create Drive for Camera When Connected

      By JovialLich · Posted

      All software is the latest between camera and app. All settings are correct on camera. I have both lossless and uncompressed RAW files on the card in the camera. I have been up and down every reddit thread to no avail and am losing my mind… I’m doing all of the right things. It even sees my camera. It just doesn’t create the “drive” for it (see attached image screenshot).  Please Help!

      X-T30 II Eye Sensor + LCD Image Display viewmode not working

      By grizzski · Posted

      Not sure how to delete threads, but I figured out what was wrong. In short, I was partially misunderstanding the view-mode's function. Also, the "+LCD Image Display" part requires that you have the Image Disp. setting set to anything but Off. Then it will display your last image on the LCD. If it's off, it's behavior will be exactly like the plain Eye Sensor setting.
