I wrote a small program in Processing that slowly, painfully chugged through 9 sections of the 17 7.1MP jpeg images of this pumpkin. Because I don't yet know how to save images larger than the screen (save() and saveFrame() in Processing seem to save what's visible in the window), I wrote the program to slice up and do the work on the images in 9 pieces, and reassembled them later in Photoshop.
In techie terms, for each of the 9 sections, Processing ran through every pixel's 3 component values (red, green, and blue), and added them all up to achieve component values in the range 0-4352 (or 256 * 17 pics). Then it divided by the number of images at the end to achieve an average value for each pixel component in the typical 8-bit component range of 0-255.
In layman's terms, my Processing script blended the 17 source images together into 1, which yields the desired effect of removing the noise.
The image noise represents a very small disturbance to the normal colors in the photos, otherwise the photos would seem to be mostly noise. As such, blending a large number of images together puts more real image up against the noise, and so the net result is greatly reduced noise. This becomes much more obvious in the actual-size blowups of certain areas of the images, which you can see in the next 3 pics.
Roll over the above image to see from where the next 3 side-by-side comparisons come.
Order: Diptera
Family: Bibionidae
15 exposures stack in Zerene Stacker (method DMAP)
Mixed light (flash + natural light)
Family: Apidae.
The bumblebee has been found already dead.
76 stacked images captured by a focus step controlled (using Helicon Remote) Nikon AF-S VR 105mm f/2.8G and 32mm extender. The raw images are preprocessed using Lightroom CC, all converted to Tiff and stacked using Zerene Stacker. Finally postprocessing using Photoshop CC.
Saw this guy on the windowsill the other day (I think it's a mosquito) so I busted out the ol' macro adapter ring.
Of course, macro rings aren't the best way to go, so I tried my hand at focus stacking. This is a stack of six images, not too bad for a first attempt.
This photo is based on 10 stacked images captured using a microrail with 250um step-size. Lens: AF Micro-Nikkor 60mm f/2.8D and 68mm Kenko extender rings. Nikon D800 settings: fully manual: 1/200 sec @ f/18, ISO 100. Flash SB900 at 1/8 power.
The raw images are first converted to Tiff (Lightroom CC) and stacked using Zerene Stacker. Post-processed: Photoshop CC and Lightroom CC.
The diameter of this little flower is approx. 7mm.
Some of te little legs of the beetle are already visible.
This photo is based on 21 stacked images captured using a microrail with 200um step-size. Lens: AF Micro-Nikkor 60mm f/2.8D and 20+36mm Kenco extender ring. Nikon D800 settings: fully manual: 1/30 sec @ f/11, ISO 100. No flash.
The raw images are first converted to Tiff (Lightroom CC) and stacked using Zerene Stacker. Post-processed: Photoshop CC and finally Lightroom CC.
Larvae became a pupa in only one day time.
This photo is based on 26 stacked images captured using a microrail with 250um step-size. Lens: AF Micro-Nikkor 60mm f/2.8D and 20+36mm Kenco extender ring. SB900 flash at 1/32 power. Nikon D800 settings: fully manual: 1/160 sec @ f/11, ISO 100.
The raw images are first converted to Tiff (Lightroom CC) and stacked using Zerene Stacker. Post-processed: Photoshop CC and finally Lightroom CC.
Stages of flower development in Lemon-scented Teatree Leptopspermum petersonii, my garden, Geelong. Insects love these flowers.
A series of photos showing flower development from bud to seed case. Melaleuca, possibly M. decussata, a shrub in my garden, Geelong. The flowers are about 2 cms long.
Red Rod Eremophila Eremophila calorhabdos, in my garden in Geelong. Four photos showing flower stages from bud to seed capsule.
This plant grows naturally in an area north of Esperence, Western Australia. It is of lanky stature but I have planted three together and it looks good. I also prune the top third occasionally to promote branching.
Another couple of first attempt at macro photography images, this time a spider (as if you couldn't guess).
The photographs should be shared only with permission, and in the form they have been uploaded here, with no cropping or further editing, and the watermark must remain in place. Copyright on all these images remains with the photographer, Neil Fellowes
I found this dead Bee near the apple tree and it was decaying so I brought it in for some photo sessions. This time I used 4x objective mounted with an Sigma macro lens and it turned out conceptually ok. This stack comprised of 62 images, each with an 0.01mm increment steps
