Grevilleas Focus Stack by Tom Brassil

January 2021 - Grevilleas Focus Stack

About the Image(s)

Image from my garden, early morning shoot as I wanted the early sun as a backlight to the flower. I needed several attempts over several days as the slightest movement caused by wind destroyed the image I was after (frustrating).

I took some 80 images at ISO 64, at 1/100 sec, F 5.6 distance to the front of flower 10 or 12 CM or around 3 inches. Imported into Helicon Focus, and after several attempts decided on the settings of Mode B, Radius 4 and smoothing 4 (if you are familiar with Helicon) utilised about 50 images for the stack. Also needed to resample several areas to account for overlayed similar focus areas. Photoshop, not much done to the flower, the background was darkened and a slight blur to draw the attention to the flower.

The Grevillea native to rainforest and more open habitats in Australia, New Guinea, New Caledonia, Sulawesi and other Indonesian islands. The species range from prostrate shrubs less than 50 cm (20 in) tall to trees 35 m (115 ft) tall. Common names include grevillea, spider flower, silky oak and toothbrush plant. The brightly coloured, petal-less flowers consist of a calyx tube that splits into 4 lobes with long styles. They are good bird-attracting plants. Honeyeaters in particular are common visitors.

Happy New Year. This is a very well thought out image. The back lighting works very well. The green background give a nice depth to the image. I also like the soft color palette. Stacking 50 images sounds like fun. This is a very strong image.
Best regards,

Tom - What an interesting and intriguing flower. I particularly like that you have chosen a specimen that hasn't fully opened. The colors are beautiful and enhanced by the lighting and background you've captured. Nice job! Happy New Year!   Posted: 01/09/2021 00:46:21

Hey, Tom, I am in TOTAL AWE of your perseverance in this focus stacked shot. I have done focus stacking in a studio type setting where there is no wind, etc and still have problems with each image being in perfect register. The fact that you did this with 80 images AND outdoors and still getting them to align in perfect register is beyond amazing. VERY WELL DONE!!! The image is to my eye a bit flat. Under the rubric of "go big or go home", you might consider ramping up the colors and exposure and removing distracting details. See thumbnail. Just a suggestion. Nevertheless, well done.   Posted: 01/09/2021 09:40:27

John, Thank you very much for that comment, I am always worried about going to far with saturations, haoebver Thanks for the input and I have had a play with the image and agree that a tweak of saturation would not go astray. Wishing you good shooting in 2021   Posted: 01/09/2021 16:49:35
