My first Infrared Experiments

<p>I shot some Rollei IR 400.</p>

<p>This shot was essentially focused just less than infinity.</p>

<p>Notice that the trees in the background are out of focus, but their reflections in the water are in focus. And the foreground twigs are close to focused.</p>

<p>Also the blackened sky is not translated in the the reflection of the sky in the water.</p>

<p>Cool, but unusable effect.</p><div></div>

<p>Thats why you need to bracket your focus when starting out with IR. It's handy to have a lens marked for IR. I didn't even know I had any until I started shooting IR.</p>

<p>On my screen, the shot still grabs my interest. Don't be too critical of something like focus - it is only technical. Composition is what grabs the eye first.</p>

<p>Curious, and interesting.<br>

If I offend I do apologize beforehand as it is not intended.<br>

I performed a simple modification of your uploaded image in Photoshop.<br>

First upload ---></p><div></div>

<p>And I, then, 'flipped' your image.<br /> Rollei IR 400 is good...<br /> and so is your image!<br>

Second upload ---></p><div></div>

"what F stop did you shoot?"

F/22.

"And I, then, 'flipped' your image."

Lol. That was my problem, I was holding the camera upside down. /chuckles.

No offense at all, Thank you.

<p>Thanks very much. I needed this! :)</p>

<p>Well spotted Josiah. <br>

A follow up question: Are there any objections in using the smallest apertures like f/22 or f/32 in IR photography? Does IR light suffer more from diffraction than visible light?</p>

"Does IR light suffer more from diffraction than visible light?"<br>

*****<br>

Yes. And the consequence is that the focal plane you focused upon will not be as sharp as you imagined. <br>

"You pays your money and you takes your choice."<br>

Many older lenses have a red "R" on the focusing ring. It indicated where, after normal focusing, the focus should be adjusted for IR film. Even so, it was an approximation as IR filters vary in their 'cut' and IR film varies in sensitivity.<br>

Experience does help some aesthetic choices.</p>
