Camera details:
• Olympus E-30
• Zuiko Digital 70-300mm f 4.0/5.6 lens
• Polarizing filter
• Save to Olympus RAW (ORF)
• Panorama stitched from seven images.
Workflow
• rawtherapee v4.2 to "develop" seven RAW ORF (Olympus RAW) images. For each of the seven adjust their exposure to -0.5ev, 0.0ev, and +0.5ev. Save each exposure to a 16-bit TIFF for a total of 21 TIFF images (7 images x 3 exposures = 21).
• enfuse v4.1.2 to blend each image's exposure stack. I.e. (en)fuse the -0.5ev, 0.0ev, and +0.5ev images into a single 16-bit TIFF image. In the end there will be a panorama stitched (next step) from the seven (en)fused TIFF images.
• hugin v2016.0 to stitch a equirectangular panini projected panorama image from the seven enfused 16-bit TIFFs. Save the panorama as a 16-bit TIFF image.
• Perform noise reduction with Noise Ninja.†
• Back to rawtherapee v4.2 to boost constrast, increase saturation, and lastly down-scale and save as TIFF image.
• gimp v2.8.10 to add a copyright string to the image. Save image to JPEG.
• Apply output sharpening with Focus Magic.†
• exiftool v9.46 to copy the .ORF EXIF tags back into the final JPEG. And to set other tags, e.g. keywords.
• digikam v3.5.0 to geotag image (using its GPS track log time-correlation feature).
• Linux Kubuntu 14.04 LTS (Trusty Tahr).
• MSI GT683 laptop with an Intel i7-2630QM Quad-core 2.0GHz processor and w/16GB RAM.
† Noise Ninja and Focus Magic are Windows applications. In order to run them on Linux they are executed via WINE v1.6.2.
2500 hours across five years went into creating one of the most exhaustively complex and unique images I have ever created: "The Snowflake", featuring >400 snowflakes all in relative size to one another.
It's up for auction as of this minute as an NFT: opensea.io/assets/0x495f947276749ce646f68ac8c248420045cb7...
On average, 40 separate images are combined for each snowflake photograph. This is required to get the crystal in focus from tip to tip with a process called focus-stacking. Due to the nature of the subject and the hand-held approach to photographing each snowflake, 4-5 hours are spent on each image in post-processing.
Measuring snowflakes is a time-consuming task, and the right equipment is needed to get accurate results. Thankfully, a hidden piece of metadata recorded by the Canon MP-E 65mm F/2.8 1-5x Macro lens makes this possible: the magnification factor. Combined with the physical size of the sensor and the total number of pixels across the sensor, an algebraic equation allows us to calculate the number of pixels per millimeter and measure the crystals.
The process of measuring snowflakes is made more difficult by the removal of certain metadata when editing. The “magnification factor” value is stored in a special area of image metadata called “makernotes”, and can be extracted by tools such as exiftool. This special section of metadata is removed from the file when processed through any Adobe software (and I’m sure others), requiring me to revisit the original raw files for each snowflake to obtain the proper value.
The largest snowflakes measure just over 11mm in diameter, and the smallest are 0.2mm across. Different storms create different kinds of crystals, some symmetrical but always unique. No two snowflakes falling from the sky will ever be identical. This poster shows the beauty in their variety.
Aqueduc du guindy. Il y a encore le tuyau en fonte mais une grosse fuite déverse l'eau dans la rivière.
La dolérite est sombre et basique à la même composition que le basalte. Quand les roches n'ont pas la même dureté le dike peut faire un mur comme une digue (d'où le nom). Voir www.editions-apogee.com/curiosites-geologiques-bretagne-t... (Un plan plus large et en noir et blanc).
One of the large number of common wasps (Vespula vulgaris) which were climbing all over the infloresences of the purple angelicas (Angelica gigas).
They were not a 100% cool with me sticking a big camera lens in their face - but definitely more relaxed than on many other flowers.
Shot using the Canon MP-E65mm set to 2.2:1 magnification.
Since the MP-E65 stores the level of magnification used for the shot in the image's EXIF data it is possible to extract (though only from the RAW image - it is stripped when saving the JPEG in Photoshop). Using the program EXIFTool I can extract this quite handily (it's not showing up automatically in Adobe Bridge) - sen me a meaasage if you want me to share how do this for your MP-E65 shots.

Bolder conversion of www.flickr.com/photos/144837857@N06/51719126945/in/photos... , gaining the lens sharness module in DxO by editing focal length with EXIFTool vs. my former attempt to use USM for sharpening.
“The Snowflake” is finally complete. 2500 hours across 5 years, this poster print represents that largest project I have ever undertaken. Depicted in this image is over 400 unique snowflakes, all accurately measured and scaled to that they are all in relative size to one another. The poster print is currently available for pre-order shipping in January, but I have “artist’s proofs” available right now that I’ll be shipping as the orders are placed.

This print not only shows the beauty of winter, but it’s an eye-opening experience when you dive into the details. The working file on my computer is 12 gigapixels in size, so I could theoretically make 60” x 90” print at 480dpi if I wanted, losing no detail in the process. When working on the file, my computer uses over 100GB of RAM, so creating something like this required impressive technology to boot.
Five years of photographing snowflakes, all with the same technique. I knew there was a reason why, and here it is: “The Snowflake”. Please let me know your thoughts!
