Three garden flowers

This is one of a pair of "hello" posts. (The other one is this post of three invertebrates in the Abstract/Macro/Still Life/Digital Art forum.)

These are from my archive as I haven't done much photography so far this year, having I think burnt out a bit doing too much in the second half of last year trying to sort out new arrangements for photographing invertebrates. Luckily, with spring coming I can feel my enthusiasm returning. :)

#1 As for almost all of my botanical subjects, these images were captured in our garden. (My wife is the Gardener, the one with the knowledge and the vision. I get to dig holes, clear away dead leaves, manage the compost heaps etc, hence my username.)

This image was focus stacked using 32 JPEGs extracted from a 6K video captured hand-held in natural light with Panasonic's Post Focus function using a Panasonic G9 micro four thirds camera and an Olympus 60mm macro lens. The JPEGs were extracted from the video, aligned and focus stacked with Helicon Focus using two different stacking methods and then merging the two stacked images and post processing the merged image in Lightroom.

#2 This is a single-capture image probably captured using aperture bracketing. (This gives me a set of captures from maximum to minimum aperture at one stop intervals with a single press of the shutter button. I can then make a carefully considered selection of which to use during selection/post processing, with the decision mainly based on the balance between focus coverage of the subject on the one hand and on the other hand the rendition of the background.)

The image was captured in natural light using a Panasonic G80 micro four thirds camera and a 14-140mm lens, probably with a low power Canon 500D close-up lens. The raw file was processed with DXO PhotoLab and then Lightroom.

#3 Sometimes I enjoy the challenge of using equipment which is not well attuned to the task in hand. This image was captured in natural light using a Panasonic TZ90 travel camera (small, flat, fits in a pocket, with 20 megapixels crammed on to its small, 1/2.3" sensor, and a lens that goes from 24mm to 720mm full frame equivalent). I don't recall now, but looking at the images in the set this one comes from I think it might have been an experimental session where I rigged the camera so it could use close-up lenses. If so, it would probably have been a Canon 500D close-up lens.

The raw file was processed with Lightroom and then Topaz DeNoise AI.

Very nice work on all of these garden closeups. I have read about using video for astronomy imaging but not for closeup work but the results in your first image here demonstrate that it works quite well. I love the colors of the blooms in the last image.

Fantastic set. I am also intrigued by using video for close ups. Dos the focal point change during the session? Also intrigued by aperture bracketing. I need to look and see if my Canon R5 supports that.

These are great Nick! I especially like #1 with the dual buds, one more open then the other. It really makes for an interesting shot.

As for video, I never thought of using it for macro like this. Now I have been using video over the last few months to capture the moon, so I think I am familiar with what's going on with the video processing. It's a great idea, and one I hadn't thought of applying to doing macro like these.

Also, Alan has a Community Garden thread in the Landscape forum every Sunday, so it you have any other wider shots of your wifes garden, be sure to add them to that thread.

Thanks Alan, Ben and Jim for your encouraging comments.

The way Panasonic's Post Focus video works is that the camera captures a video as it moves the focus plane from the nearest thing it can find to focus on to the furthest. For my preferred ways of working this approach has several advantages over focus bracketing, whether manual or in-camera focus bracketing.
  • Unlike with focus bracketing, you don't have to make any preparations like ensuring the focus plane is positioned at the front of what you want in focus (or nearer), and you don't have to decide how many images to capture or what the spacing should be between them. It is quite literally point and shoot.
  • The 30 fps capture rate is good for working hand-held, which I very much prefer these days. On my cameras at least focus bracketing runs at a rather leisurely 4.5 frames per second or so. If the stack needs several tens of images (it has been up to 200 occasionally) it can make for a long time to hold the camera somewhat still in what can sometimes be rather awkward/stressful positions. The fast capture rate also makes it more practical to work in breezy conditions, which I often do because we live in a notoriously breezy location (we have a pub just down the road called "The Windmill", because that is where there used to be a windmill).
  • Rapid and easy acquisition makes it practical to have several attempts at each scene to improve the chances of getting a "take" that works.
  • You end up with one file for each take, not potentially tens of images, so file handling is significantly quicker and easier than with focus bracketing.
Aperture bracketing is another technique that I find really helpful. It is even faster to execute than Post Focus videos. For each scene I typically start with several aperture bracket sets and then do several video captures. If it turns out that stacking won't work with any of the videos I can fall back on the stills. And sometimes I prefer the look of one of the aperture bracketed stills anyway. Stacked images can have a certain somewhat "samey" look to them. Single-capture shots tend to be a bit more interesting to my eye as far as the backgrounds go. If it is very breezy I don't bother with the videos and just use aperture bracketing.

Thanks for the excellent write up.
If anyone wants to dig further into this here are some You Tube videos I made.

The first one illustrates the real world use of Post Focus video and aperture bracketing for botanical subjects.

The second and third are deep dives (both around 45 minutes long) into focus stacking botanical scenes, the first with my own video captures and the second with someone else's. They cover similar ground. Not sure which would be best to dip into.

The last one illustrates some problems with focus stacking botanical scenes and possible workarounds. This is a lot older and done when I had just started focus stacking, so I'm more competent with the stacking software now. That said, the section from 22:00 onwards is probably the most thorough illustration I've done about one of the issues I encounter frequently with botanical stacking - halos, or at least one of the most common types of halos I encounter.

Lovely work. I especially like the last one.
Thanks Debbie. With the last one I got lucky finding a composition I was ok with. I usually can't with flowers in a patch like that. The edges rarely seem to work out well, usually having something(s) half in and half out, which I'm not keen on if they are too much in focus for my visual comfort.

Nice set of images. Interesting approach and the ability of your camera to do this. Your last image is my favorite.
these are all so beautiful!! my favorite is the last one for sure love the color!!
Thanks Jameel and Alisa.

I'm fascinated that the third one is going down so well, given the camera I used for it. That camera is rather restricted in what it can do, but I suppose it shows that given decent light and a scene of the sort it can handle, then the kit isn't too important, at least for the small size images I produce. (I make all my images 1300 pixels high. Keeping them small lets me get away with some unusual techniques that wouldn't work with bigger images that could be examined more closely, although that is much more the case with invertebrates than with botanical subjects.)

Welcome to Focal World, Nick. I love flowers as you will see after being on this site for a while and I can't wait to see more of your images. Beautiful images in your first few posts.
Thanks Douglas. I see you have photographed some wonderful carpets of flowers. Nothing like that around here. :(
