@mattblaze I just got a tilt shift adapter to do work where I want to keep a plane that is not parallel to the sensor in focus, and I gotta say the process is a little more complicated than I thought it would be. Other distances in focus that I didn’t expect…
@kmck Focusing with tilt and swing movements is definitely not intuitive at first - it's very easy to mis-estimate how much you need to get the right plane in focus. Once you internalize visualizing the intersection of the planes with the Scheimpflug rule, it gets a lot easier.
Yes, this is a mastodon post where they have tagged the !newzealand community. It’s how they display in Lemmy. I’d like to think over time the integration could be refined so it didn’t show so… messy.
#photography nerditry:
I make mostly (but not exclusively) B&W images (at least for my fine art work). Is it worth using a dedicated monochrome sensor?
Most digital cameras are designed to record color, using a special mask in front of the sensor called a "Bayer filter". This allows color information to be derived from the raw sensor output, which otherwise would just record brightness. But the Bayer filter can also reduce effective resolution of the image a bit.
Many achromatic sensors (which omit the Bayer filter) also omit the IR-cut filter. If you shoot in daylight or in settings where IR is present, you have to add an IR cut filter to the lens to maintain sharpness.
But this also opens a range of new flexibility. Instead of an IR-cut filter, you can instead use a filter that cuts out visible light and passes only IR. This allows you to make (monochrome) images of the infrared spectrum, which can have a dramatically different look.
@promovicz@reinoudk Ansel Adams would get a rough preview of the tonality and contrast of a scene he was considering photographing by looking at it through a yellow filter. He even had one made with lanyard for carrying around his neck.
