FlashPix (.fpx) File Conversion

Back at the turn of the century there was file format in Kodak and other digital cameras that offered lossless compression. This format was essential back when cameras were one megapixel or less and any JPEG compression severely limited post processing capabilities.

At that time nearly all photo editing software supported this open standard file format but as camera resolutions increased FlashPix was dropped by manufacturers and the software vendors followed a little later. By the start of the last decade only a few programs supported the format and usually only in the 32 bit versions with plugins that needed to be installed and configured (hard to do for ordinary folks).

I thought I had converted everything I’d ever need back when PaintShop Pro still supported FPX but I was wrong. A decade ago I found a handful of photos I’d taken to document experiments for my job. Searching around I found My ViewPad a free image viewer that still works on modern Windows to view FlashPix files and convert them to many other file formats.

This morning I discovered 90 photos that had never been converted! Since there was such a large number of photos to convert I decided to try out some of the programs that were supposedly capable of doing batch conversion of FPX photos 10 years ago. Unfortunately none of those programs can open FPX files in 2021 (XnView/Convert & IfranView) :-(. So I’m going to have to convert these 90 photos one by one using the still great My ViewPad.

A final tip, when converting your FPX files save them in a lossless format to keep the quality as high as possible. The extra size on these low megapixel photos is insignificant by 21st century data storage standards. Probably the best choices are lossless PNG or TIFF because they are supported by every photo viewing/editing package I’ve tried.

Public Domain Images

I was about to take some quick photos of household objects for a demo home inventory system today when it dawned on me to simply look for suitable ones online. Searching around I found one great site and one that is totally clueless as to what public domain means.

First the great site, PublicDomainArchive.com, an absolutely wonderful collection of images that are truly public domain.

Now the clueless site, PublicDomainPictures.net, I found one picture that I thought I might use but then I read this on the images page.

License: Public Domain. If you are going to redistribute this image online, a hyperlink to this particular page is mandatory.

The highlighted part is completely contradictory to the concept of public domain. The CC public domain license they link to disagrees with the highlighted text.

The person who associated a work with this deed has dedicated the work to the public domain by waiving all of his or her rights to the work worldwide under copyright law, including all related and neighboring rights, to the extent allowed by law.

When you waive all of your rights you can’t have a mandatory attribution provision, you can ask for a link and many people would freely give one but making it mandatory is right out. Because they want attribution in the form of a link they need to use one of the CC attribution licenses. Considering how clueless they are, and that their one image I was considering was not that good anyway, I’ll pass on ever using or recommending their site. People who are this clueless on copyright and public domain I’ve found are often trouble waiting to happen so I strongly recommend you stay well away from their site.

A Profusion of Pipes, Cluster of Corpses, Gathering of Ghosts

Indian Pipes, Corpse Plants or Ghost Plants that is, on August third my sister was looking out the kitchen window to the woods bordering the back yard and called me to check out an unusual sight. (Click images for larger versions)

Wow! Over 400 Indian Pipes, (Monotropa uniflora) were growing in a 2 square meter area. I’ve seen this plant hundreds of times out in the woods but never more than a dozen or two in one place. With such an unusual natural event I had to take a whole bunch of photos.

Nearby the Indian Pipes, I spotted this nicely posed mushroom. My best guess at an identification is a Common Funnel Cap (Clitocybe gibba).

Normally I try to avoid disturbing native plants growing wild but, since my sister had never seen an Indian Pipe before and there where so many on our land, I picked one for her. After she’d examined it I put it in the fridge so that once I was done with work for the day I could take some macro and micro photographs.

Whenever I’ve seen Indian Pipes it has been in forest areas so I was very surprised to see two clumps of Indian Pipes growing on the grassy bank of a drainage ditch in front of my employers factory a few days later.

There are more photographs in my online photo album.

I had never seen these odd flowers growing through grass before, this had to be an extraordinary year for Indian Pipes. Witnessing this population explosion of a normally rare flower I wondered why it had happened. Being a native plant I figured the most likely cause was an increase in their food supply. Since we had experienced above average rainfall and below average temperatures in June and July I thought that was a probable cause.

Pondering my hypothesis, it didn’t hold water given my knowledge of this plants nature. Forty years ago I was taught that these flowering plants with no chlorophyll couldn’t use the sun like green plants so they fed on decaying leaf litter. To speed the rate of decay you want to increase both moisture and temperature so, while the extra rain would help the lower temperatures wouldn’t.

This led me to start searching for more information on this flower, my first stop for information on flowers of southern New England is usually the Connecticut Botanical Society. As usual I found a good summary page there with the scientific name to help me find further sources and the following description.

Indian pipe, like its relative pinesap, has no chlorophyll, so it cannot obtain energy from sunlight. Instead, it gets nutrients from organic matter in the soil.

This confirmed what I had learned decades ago so I was still puzzled why there was a population explosion. Researching further (see resources list at the end of the article for links) I found out that I and the CBS website had obsolete information. Scientists have shown that Indian Pipe does not get its nourishment from decaying material, it’s a parasitic plant! Monotropa uniflora is a parasite of fungi that are mycorrhizal symbionts of trees so, increasing rate of decay in the leaf litter wouldn’t likely be a factor at all. The unusual weather in June and July likely caused the fungi and its associated tree(s) to generate a larger than normal food supply giving this parasitic flower an advantage.

Reading through all the information I’d found led me to another mystery. Some of the sources imply or outright state that the tree involved in the relationship is a always conifer. The Indian Pipes in my yard where near pine trees and my memory is that whenever I’d seen them other places in the past there were conifers nearby. However, most of my nature explorations have been in southern New England and almost everywhere is mixed deciduous and conifer forest. So having conifers nearby is really just a default condition and not necessarily linked to the Indian Pipes.

Thinking back on the flowers I found near the drainage ditch, they were on the other side of the drainage ditch from the conifers in the area. Since the ditch is four feet wide and four feet deep it seemed unlikely that the fungus was going down over four feet through the sand and gravel base of the ditch to reach pine trees. There is only one tree on the flowers side of the ditch, a sapling oak tree a few feet away from the flowers. So I hit the resources again for more in depth reading and found that the conifer association is not stated as a requirement in the more thorough references. I suspect the little clusters by the drainage ditch are parasites of a fungus attached to that little oak tree.

With all the references I’ve studied I learned something that leads to another puzzle. The mushroom I saw around the Pipes in the back yard is very likely to be from the fungus it is parasitizing. Also a number of studies have shown that Monotropa uniflora associates with quite a few different fungi but they are all of the family Russulaceae. My mushroom identification was in the Tricholomataceae family which doesn’t fit with the literature I’ve read.

To solve the puzzle I came up with a list of possible solutions:

  1. I misidentified the mushroom.
  2. The mushroom is not from the fungi associated with the flowers.
  3. The literature is incomplete, Monotropa uniflora can associate with fungi of the Tricholomataceae family.

Applying the basics of Occam’s razor, solution 3 drops off first, multiple studies have shown Indian Pipes only associated with family Russulaceae. This leaves one and two to consider, given that I saw no other mushrooms in that area this summer that leaves number one as the most plausible solution. Big surprise, Not! Even experts have a hard time identifying mushrooms which is why I would never trust my identification and eat a mushroom I found and identified.
