I'm leaving on a new road trip next week. This time to Virginia for a dragonfly meeting. I will pick up my best friend in Wisconsin and then hook up with 2 more friends in Chicago.

As always I will be looking for dragonflies to photograph.....I have some new equipment and techniques I want to test that will increase my resolution and depth of field.

I am also hoping for some extreme weather, lightning storms and super-cells. I now have time-lapse and video capabilities as well as stills.

Night skies and the Milky Way are also on the agenda. I will be trying out some new techniques with this also that will give me cleaner sharper shots.

My wife is going to fly out and meet me after I drop my friend off and we will swing down through the Southwest and spend some time shooting canyons and exposed strata.

I am finishing up getting my truck ready for a long haul and getting music and audiobboks organized.

EvC has gotten more active recently, interesting, but I don't know whether I will be able to stay caught up. I can read using my phone most places now (when I'm not driving or shooting), but it is a pain to use to post.

Re: Ohhh gear porn!

What gear and what techniques?

Well, the Nikon D810 is new for me, I think you said you have it.

I have a 200mm mico-nikkor that I started using almost exclusively last year since my Sigma 180mm macro started malfunctioning. The 200 is noticeably sharper but I cannot use it with a teleconverter, so I need to get closer to my subject.

In the past, shooting with my D700 I mostly shot at f32 for longer depth of field and did not worry much about diffraction because of the small aperture. On the D810, the 36mp sensor is diffraction limited between f8 and f11 so depth will really suffer. I am experimenting with using an app on my android phone connected to the D810 that will allow me to set the closest focus point and furthest focus point and it will calculate how many overlapping steps need to be shot, based on my aperture and than shoot a quick stack that can be composited into a ultra-sharp, extended depth image. An added bonus is that by using a rather large aperture, f8, I should have fairly nice bokeh in the background. The app is called Helicon Remote. The free trial version will only work for jpegs though.

Of course, the trickiest part is doing all this fiddling with the phone and not having any movement of the subject. It is cool that the phone will show me what the camera sees and will automatically change the focus on the lens for each shot in the stack. Out in the bright sun the phone display will not be that easy to see....there are always tradeoffs.

Night photography: I want to tryout a technique of shooting a bunch of quick high ISO shots of the Milky Way and then using a program called Deep Sky Stacker to composite the images and remove the noise caused by the high ISO. This is a method that astrophotographers have been using for quite a while now, but I just ran across it.

diffraction
https://1drv.ms/f/s!ApoX6MpCAsdsswWnG-zWpXmNhDn3

Picture 124734 in there is at f/51 with a 105 macro on a 810 ( 1/250, hand held and ISO 1800). There isn't a lot of DoF but some of it seems sharp to me. I am having trouble seeing obvious diffraction problems (old eyes maybe).

The rest of the images are down rezed a lot.

Thanks, I will look at the helicon remote app. I haven't tried any remote control yet.

No thanks, bro. I'm hoping for sunny beaches and clear night skies!! Maybe Virgina is big enough so that we can both get our way...

Re: diffraction
Picture 124734 in there is at f/51

I went through all of them twice, but I can't see one numbered 124734. There were a couple that didn't have numbers though.

For me, diffraction is a blurring of the finest details in the areas of sharpest focus. I especially notice it when I am blowing images up for printing or when I stop my lens down too far when shooting with a microscope objective mounted on the lens.

An effective aperture of f51 must be stopped all the way down on the 105. By the way, I think the 105mm micro-nikkor is the sharpest macro lens on the market. I don't have one but my 2 best friends shoot with it.

I don't know if you have ever used this Cambridge In Colour website about diffraction, but I have found it to be pretty useful. LENS DIFFRACTION & PHOTOGRAPHY

I am having trouble seeing obvious diffraction problems (old eyes maybe).

I hate having old eyes, but what can you do.

I think I put the picture in the folder after I got a link from onedrive. When I added an additional foto it gives a new link. I forgot that again.
/abe
no it is the same link and the pic is there. Onedrive may not have gotten it uploaded yet since it is just under 17 Mb.

D820
How bad will this be when we get about 46Mpixies later this year? And the files will be over 50Mb.

Re: D820

I have not seen any info about the D820. It is always fun to read about features on new cameras, but with digital the past few years, the incremental improvements of features have mostly been been frustratingly small and there is a bewildering array continuously released new bodies.

I think the removal of the anti-mosaicing filter from the sensors on the D800 series cameras has helped compensate for some of the effects of diffraction.

The megapixel wars are entering the absurd in my opinion. Primarily because there are fewer and fewer lenses that are capable resolving image details that take advantage of photo-sites that small.

The file size on the D810 is a pain to deal with when I am shooting deep stacks. Zerene Stacker cannot use raw files so they either have to be converted to TIFF at 211 megabytes or saved as TIFF to the memory card at 105 megabytes. Processing 500 images that are 105 mb in a stack strains even my high-end computer.

Hey, I am traveling to VA next week!!

Well, we probably won't get there until June 7-8.

I'm hoping for sunny beaches and clear night skies!!

I am also, once we get to Virginia. Coming across the plains though, I am hoping for anything short of death or injury from tornadoes and thunderstorms.

I'm in too much of a rush this morning but I'll update you in a few hours. That site is a bit slimy but I ordered one anyway after checking for it through other sources.

Sweet. How much was it? I have a nephew photographer who might be interested.

Watch the price
I have a few mins before an appointment.
First the $149 "regular" price appears to be bullshit. They offered an additional 30 % of the price that first appears and that brings it to what the real price should be -- $39.

My challenge will be that it is meant to screw to the bottom of the camera and I keep arca swiss plates on the bottom of mine (actually L brackets on both of them). I'm going to look at putting it on my travel tripod with a plate bolted to it but haven't had time to research it yet.

I will let you know more after I get it.
