I was getting jealous of all the robberflys. Then in the last week I have seen the wasp mimic, Laphria index, and the bee mimic, Laphria thoracica. In this article on the wasp mimic, it shows them eating a weevil(?) that I noticed on the walnut and butternut trees I was examining for blight when I saw it.

I have photographed this bird about 500 times. I have shot it form distance and close. Unless the sun is at it, and I am in the right location it is a sparrow. Luck is the only thing that matters. Indigo-bunting-singing by swanlefitte, on Flickr
at best a longer lens would allow me to get this shot from farther away.

Even if a burst was fired, why does one make a good photo compared to the rest? Every one of my best nature photos have an element of luck. Even if I had the best lens, most shots would be bad. Only when the bird, the light, and the environment work together do I get a really good shot. At best, a longer, great lens, would still give me a better shot.
In short, a great lens lets me get a better mediocre shot, or a better pre-planned shot. The "hero" shot is all about being there.

Clackers' Beginners Tip 27: Conjunction

As usual I enjoyed the post and it got me thinking more about the topic. I am constantly working through ideas anyway. So some might enjoy some of my insights (or not).

I was just watching a guy talk about how communication needs to ground the audience. Doing photography, we always hear how a photo needs to tell a story, but a story is just one way to ground the audience. A situation in nature yesterday and this tip and photo worked in conjunction to get me thinking.

I really like your photo but there isn't much of a story. What your photo does is ground the audience. The geometric similarities and layout, and the light and dark is something our minds can relate to. The hands ground us to the human quality and the position shows us the ball is above. In my mind, the ball is going up and the sun is going down because the photo is anchored(grounded) to those concepts. In reality the sun could be going up and the ball dropping but the visual cues that attach me to the photo and allow me to connect say otherwise.

I mentioned my nature encounter as another reason for my thinking about this so I will tell that too. A doe and her two fawns came through the woods and were surprised by us. I wanted a shot that showed this. My first shot was wide to capture all the information. I got that. It was a "snap shot". The one fawn stood behind the mother and the mother was half obscured by vegetation. The other fawn was not very close. I had a photograph of the encounter but not of what made the encounter meaningful to me. There was nothing to ground it. There was no connection between me as the viewer to any of the deer and the brush worked to disconnect me and the deer. I focused on the single fawn and got that connection even though I lost much of the information.

Your photos has a low sun and hands, it has the shapes, it grounds the viewer, more info isn't needed. Knowing the size of the hands and the size of buildings allows us to know the sense of space. More info isn't needed. The conjunction then focus's our attention and makes the profoundness of this space tangible. The conjunction of the symmetry of the circles and the square frame also gives this. I think if it was framed in a rectangle, losing that conjunction would upset the stability. The photo contains just the info needed without extraneous info to distract. The conjunctions act as means to attract our attention to the relationship.

Thanks for getting me thinking. Beginner's tips are attached to the rest of the iceberg.

Maintainance of CMOS or memory or backup-battery

So you perform CPR on the battery! Do that for 30 minutes then listen for signs of life and continue. Until I have heard of many successful stories or until I have a doctor to call it, method b is the way.

It seems like it could be tested by rigging a dead CMOS battery out of a camera up to some automatic switch directly to it. One could then test with variables also.

You have to decide what compromises are best for you.
The ks-2, 55-300 plm and the 1.4x tc is best for me. I go on local park safaris every day. I ride my bike to the park with just that combo on my camera around my shoulder. I do some post to clean up. This is a typical shot. I had to use a 2000 shutter to stop motion and ISO 2200. I still cropped the height down to 57% original frame on my ks-2. heron-fishing-without-a-worm by swanlefitte, on Flickr

Here is another "safari" shot in winter light. at 364mm. (364mm gives f/8, any longer goes to f/9.5) at 1600 shutter and 400 ISO. The coyotes are about a football field away. This is not cropped. coyote-date by swanlefitte, on Flickr

granted that I don't print many and they are for documenting and remembering the moment mostly.

I did print this one to hang in the bathroom. It was shot at 266mm so I didn't need the tc. tall-ship-and-refinery by swanlefitte, on Flickr

Had to look it up. I would believe Saint Peter is in his tomb. The Tomb of St. Peter is located in the depths of St. Peter's Basilica in an area called the Vatican Necropolis. It is believed that after the death of St. Peter, he was buried on Vatican Hill, close to the site of his martyrdom. Visit St. Peter?s Tomb | An Underground Treasure

Yes you can trade 1 stop of light for 1 stop of pixels. Do you want a larger size or a brighter smaller picture. They are the same. That smaller brighter photp will lose at the bigger size. That bigger size will gain brightness at a smaller size. or the trade off of noise by amplifying the light as you shrink the photo.

This is general for 2021 and doesn't mention standard deviations that should be expected. A consumer survey in 2014 said consumers expected a digital camera to last 6.5 years. Consumers expectations are presumably higher than industry standards and 2014 standards have probably become less since 2021.

To me that means it is a hinderance on a decent image but worth placing a bet on a unique image that didn't technically turn out to salvage it. This also means I would never spend enough time to find out, probably. The person who takes the time might be like a card counter in Black Jack and know when to hold or fold em.

I am not pro or con Tony. He is honest yet often not informed enough.

I liked seeing at 11:40 the upscale vs real at the same size. Often he doesn't reveal that his info is at unrealistic viewing sizes. He does say we see 300% viewing size at times but when is he showing other sizes? I don't know. Can I see the stars are blobs at actual viewing size? I don't think so but he skims over that incredibly important point..

Like all data, I would look at it carefully and see if this software obliterates it or enhances it. I love the tool but not the authority or confirmation.

Here is a noise comparison. I used the dpreview images from the k1 and k50 because they have the same pixel density. The k1 at ISO 1600 and k50 at both ISO 1600 and ISO 800

You can see at 100% the noise is about the same at ISO 1600 but the k1 image is much bigger. The k50 at ISO 800 is better and smaller. But when you enlarge it 1.5x so you view at the same size the noise advantage is gone. You do not really lose a stop of light.

alternatively I could resize the k1 image down to look like the k50 800 noise level. (Sorry I labeled the photo as K5 but it is K50)

I forgot the primary reason I use it and I had just taken an image on friday.

reason 5 to get focus on the eye instead of a branch. The bigger the eye is, the easier it is. It is still not easy when the bird is moving around and the branches are not, especially when you are standing on uneven ground in marsh and have to crouch to get through the branches in the first place.

If I had a k1, these would be the reasons I would use it. They already apply with my ks-2 and 1.4x.

reason 1 is you may be able to fill a bigger frame if you can get close enough.

reason 2 is if you can fill the frame you get more pixels. This also gives you the option to downsize to the crop sensor size and reduce the stop of noise to par with just cropping.

reason 3 is to change lenses in the field without exposing the sensor to the elements.

resaon 4 is to make my macro a 1.4:1 macro or give me working distance at 1:1. giving the extra magnification at minimum focusing distance already makes my 55-300PLM great for 1:2 like butterflys.

There is a sweet spot between number of pixels and the fuzzy discs the lens produces given the pixel size of the sensor. Crop too much and at viewing size you enlarge the discs too much. Crop too little and your subject is lost in the frame. At the same time if you crop, you also magnify the noise as you have to magnify the viewing size.

It certainly isn't a perfect way. It is just one way of implementing compromises like all the rest and has some advantages and some disadvantages.

I enjoyed reading about the sdm conversion even if it doesn't concern me.

I do use back button focus and the one concern I have is that focus doesn't wake up the camera if it falls asleep. Can you find a joke or solution to that before next week? I never think to press the shutter because I never realize the camera is asleep until it didn't respond in time.

So true. It is a herculean task. I looked at a calculator to put that into numbers.
With a FF camera and a 300mm lens at 2 meters the vertical is estimated around 136mm(160 at infinity focus) and a bird is close to 50mm so you still only have 1/3 of the frame IF you don't have breathing in your lens. Getting as close as 2 meters away is almost impossible.
with 420mm best estimate is still 90.3mm(114mm at infinity focus) but I can also stand 2.7 meters away and still get a vertical of 130mm(154mm at infinity focus) This gives me a much better chance of being far enough away that the bird doesn't startle.

But also look at noise. I get to either use 1.4x the number of pixels or I get to use less with each pixel having 1.4x more light. Viewed at the same size neither will show more noise than the other. If I view each at 100% the bigger photo will have more noise but only because it is bigger.

edit: I wondered about the angle of view estimate so I tested it out with my set up, the ks-2 55-300 at 260mm and the 1.4x tc. at about 2.7 meters my angle of view was close to the number given by the calculator but between that number and infinity focus. The tc didn't have any change. It was 1.4x magnified in the photo.

I used this tool. It notes close distance calculations are approximate see notes at site. https://www.pointsinfocus.com/tools/depth-of-field-and-equivalent-lens-calculator/#{%22c%22:[{%22f%22:13,%22av%22:%228%22,%22fl%22:50,%22d%22:3048,%22cm%22:%220%22}],%22m%22:0}
