How to Geo Tag your Photos

This is not meant to be a step by step guide.

The easiest way is perhaps just use our iPhone, the pictures are geotagged unless you turn off the location thingy in the setting.

I think many years ago I tried that already.  Back then I was using an Android phone and some Nikon D7000 camera I believe.  But things haven't changed much for me since then:  my cameras still lack GPS.  I still don't have any commercial reason to geo tag my pictures other than I feel like to and because I can.  When exporting my pictures to JPEG, my routinely remove GPS data even I don't have them to begin with.

One of the few things I discovered is that Lightroom enables me to geo tag my pictures with the Map module (or whatever parlance Adobe uses).

So all I need is a software that allows me to create a GPX file from my iPhone.  I just downloaded one from Open GPX Tracker.  I proceeded to set the camera clock closest possible to my iPhone's as I suspect time will be used to match the picture taken to the gpx file time data.

Once I got the GPX file to my computer and Lightroom can just use some magic to get the GPS data to the picture files.  If I don't want to be precise I can perhaps just drag whatever pictures to a location that's close enough without even the use of any GPX files.

So I just save myself some $90.  Adorama used department sells some GP-1 for $59 or so without explicitly stating whether cable included or not so I take it it doesn't while KEH sells one for some $90 with cable included.  I checked NikonUSA, the cable is selling the cable for $69.99 while I don't seem to find any pricing for the GP-1 or GP-1A, I think the 1A is the latest model and NikonUSA doesn't bother to say the difference.  I have to find it out with a Google search.  The 1A has some bigger screw on for better secured connection ... or something but feature wise, they are the same.  Anyway I won't be buying one with or without the cable.

Photoshop and MacPro3,1

Photoshop simply won't load when your chip is old as the one in MacPro3,1, the 2008 edition.  I have done some searches on this topic and finally got some workarounds.  Unfortunately those workarounds don't workaround for me.  Again, after a day or two intensive digging I have to give up on it.  It's not worth the trouble.

D4s and D700

I've always like the pictures from my D700.  There is nothing objective or scientific about it, it's just my beliefs.

I usually shoot with my D810 and D700.  The D700 seems to give me more accurate focused pictures.  The shutter and mirror sound is loud and oddly reassuring.  Despite or because of its 12MP, I really don't know, I think the pictures always look sharp and clear.  It has that clarity.  I am not saying the D810 is bad, actually when I shoot with the 16-35 f/4 with flash and pan I got some very solid pictures.  I actually find this is my sweet combination.  Still there is something about the overall clarity of the pictures from the D700, the color is not as rich or deep as the D810 but in most situations I find them nice or nice enough.

Fast forward to D4s, I haven't bothered to do any test except one if you can even call it a test.  And it troubles me that the pictures don't seem as sharp as the D700 ... though it's only based on one single event.  I even tried to do some test, like with tripod and strobe with fixed shutter speed and f-stop between the cameras.  The result is virtually identical between the D700 and D4s.  Alas, I was shooting at 1/250, f/16, ISO 400 with qflash at manual output at 1/4.  I guess I should have done a set at f/2.8.  Sometimes when I shoot cycling event and the D700 returns sharp pictures, and at the line up I can see the pores of the face.  I haven't got the chance to shoot with the D4s on events like that.  I hope the camera can return same or better results than the D700.  It's hard to believe if it doesn't but then you never really know I remember reading some online (!) review saying the D4s images are soft and have Nikon USA checked out the camera.  I don't want to be that buyer.  I don't think it's the AF as I feel the AF is accurate.  I've never done any AF fine tune with any of my cameras, not before not now.  Maybe it's the lighting condition.  When there is not enough light or contrast it's hard for pictures to look sharp.  I will find out from real life shooting soon enough.  This kind of first world problem is annoying and embarrassing.  When I tell people this kind of problem I imagine people would just roll their eyes.

Nikon Firmware Update

 Nikon is not particularly clever when it comes to software.

It has firmware and the lens control in two separate bin files.   I copied the two bin files to the root of a CF card thinking that it would do them in whatever sequence as necessarily.  The typical user behavior thinking what the machine would do instead of just following the damned instructions which by the way doesn't say you can't have both firmware and lens correction exist in the CF card at the same time.

The firmware upgrade was fine.  But then the camera would only pick the firmware where it's there in the CF card even both the camera and the CF card has the same one.  It even ran the whole firmware upgrade even the version is the same.  It simply won't go a step further to get the lens control bin.  Once it sees the firmware then it just does that nothing else.

Me being a relatively intelligent guy so I removed the CF card from the camera and plugged in to the computer and delete the firmware bin file.

Once the firmware bin gone from the CF card, the camera knew to update the lens correction.  So that was it.

Dickies work pants

 I have a pair of navy blue dickies from way back.  I don't remember when I bought them, but as far back as I can remember they were in my wardrobe.  I think probably more than 20 years or so.

I wasn't a big fan for two or three reasons.  I outgrew the pants soon enough as I started to grow horizontally in my mid thirties.  And the pants are true to size and really hit the waist instead of low.  Also it's not 100% cotton, so in terms of breathability it's not exactly great.  But if you want your pants creased then they maintain the crease quite well, which I find it quite interesting, I meant these are considered work pants.  But I guess back back back in the old old days, workers are expected to be well or properly dressed and groomed.  Another funny thing, at least in my book is the belt loops are relatively small or narrow, not for big freaking belts but for narrow belts.  So again what is the deal.  If you have some cowboy belt it's not going through those narrow loops for sure.  Again perhaps the idea is to make these work pants more like dressed pants with small belt loops* and creased legs, I could only reckon.

They are pretty well constructed and durable.

After some twenty plus years I ordered online another pair.  And this time around I ordered online directly and I chose the Lincoln green color.  I think that's the color for the sanitation workers here in NYC.  I am just fascinated by that color.  Black and navy blue are the most common work wear colors and Lincoln green kind of special.  The model name is 874 which I think is the original cut instead of some more updated version like slim fit or something something.

*Serious dress pants should never have any belt loops anyway.

Flash Duration

 Flash duration seems like an easy concept... What I don't understand is how does it come into play if your ambient light is like sunny f/16, with lots of sunlight?

If your camera shutter speed is set at X sync at 1/250s with a shortest flash duration, will that even matter at all?  As the ambient is continuous sunlight, how does a short strobe duration helps freezing action in this case?  I understand if your ambient is jet black then sure, even if your shutter set at 1s, if your flash duration is short enough then you can freeze the action.

I read and watch, and people keep talking about flash duration or a very short flash duration helps freeze action.  But they never mention only if you have no and very low ambient.  Am I missing something?  I really want to know.

I think a long flash duration and high camera shutter speed with well timed shutter release, that is, hyper sync works better in broad daylight.

Hypersync hack using SB-800 and a pair of Sunpak 120J

 I have a couple of receivers and a transmitter that say

Frequency 433MHz, Service range <= 30m

Sync Speed >= 1/250s

Receiver 2x1.5*AAA battery.

These radio trigger can't do any high speed sync or hypersync or hi-sync ...

However if I were to attach my Nikon SB-800 to the hotshoe of say my D700,  Hypersync from my Sunpak 120J is possible.

I need to run a sync cable from my SB-800 to the transmitter.  Then connect the receiver to the sync terminal of the 120J.

The D700 is set to do AUTO-FP at 1/250.  Honestly I don't know if it's at or above or just above that speed then the camera and the speedlite will do the high speed sync, that's producing pulses of light as if continual lighting for the duration of the exposure.

For this to work relative well, I have noticed the following.  There is really no black band on the frame but for high speed and small aperture, say 1/1000 and f/16, the picture looks darker.  And the bottom of the picture looks brighter regardless.

Let's say I shoot about 10 ft away subject to 120J, at full power, and it says f/16

My SB-800 is set at 1/128 power as I only use it as a trigger not as a flash.

So here is my settings

D700, at 1/1000, f/8, 2-stops lower than my 120J says.

Sunpak 120J: full power

That's it, full blast and the picture looks good no black bar at the bottom.

Conclusion:

I have a pair of Godox CellsII-N which is bigger and supposedly do some hypersync.  But the trigger sometimes fires randomly.  So I don't like them.  Plus it's only 2, one is transmitter one is used as a receiver.  So any time more than 1 light is impossible.  Even though most of the time I shoot with one off camera light anyway.

With this SB-800 hack I can run two 120J at full power blasting off and still run at 1/1000 or higher and the triggers is cheap and pretty reliable in my book.  It can run at regular sync or hypersync, so it's all good.  And if I want I can run the SB-800 as fill flash as well in addition of being a trigger only; so three lights.








Strobe qflash model T

 Latest fascination

The Quantum qflash.

I couldn't find any difference between T and T2.  I think if I don't ever use any TTL then perhaps it doesn't really matter.

One is untested and is on its way.  I am taking a chance as it says it's untested except it can power on.  What does that mean, the most optimistic scenario is the unit actually works it's just than the vendor is being very forthright telling you that the unit hasn't been fully and completely tested.  I wonder how many sellers actually test the whole feature set, I mean do they see if the flash duration is actually within spec at 1/2 power for example?  I don't think so.  Or the TTL actually works?  Or the slave feature works?

Instead of getting an extra Powerpack like the Godox PB 960, I opted for the silly power pack from maxxpower.  When I first got my Sunpak 120J that's what I got for the power.  But now the powerpack can no longer be charged.  I wonder if it's because it hasn't been used and needs to be awaken.  But then I have no way to awake it or know if it's just sleeping.

Also ordered a TR 2000 cable, which doesn't fit right into the Sunpak 120J; it needs a 3 to 2 prong adapter which I have with the original TR-PAK II I got years ago.

Or I can order a quantum turbo extension cord QT49 to run 2 120J from one PB 960.

I sort of create my own problems and look for solutions on eBay.

2015 MBP SSD and Big Sur Upgrade

 If you do a search you probably would find lots of pertinent information.

The 13" 2015 MBP is on its last leg on being able to upgrade to the current macOS.  There is no way I can upgrade my 2008 MacPro and 2012 MBP to Big Sur without major major hassles.  They are in Catalina already.

The original 13" 2015 MBP came with 128GB of SSD.  This certainly on the meager side.  I changed the battery a few months ago after it started to bulge.

I gathered 3 items to do the upgrade.

1. The Rongdeson M.2 NVME SSD enclosure

2. SPG SX8200 PRO 512GB

3. Sintech NGFF M.2 adapter card

I didn't bother to backup anything on TimeMachine or otherwise.  Just do it.

Put 2 into 1.  Connect to the MBP, erase the new SSD into APFS and the rest default values.

Upgrade the MBP to Big Sur by downloading and installing on the new SSD

The upgrade will prompt you for anything it needs and it also prompts you to migrate your existing Mac to the new Mac, ie copy the old SSD data to the new SSD.

After the migration, the last step is to turn off the MBP, open the bottom cover, unplug the battery, remove the old SSD.  Remove 2 from 1.  Then slide 2 into 3 completely.  Take 3 with 2 attached and plug 3 into the existing slot, make sure they are inserted all the way.  It's like at an angle, seat it and screw it down.  Plug the battery.  Put the back cover back on and the screws.

Turn on the MBP, answer a few prompts like verify your Apple ID and stuff.  That's it.



this is the swapped out old 128GB SSD, it's not M.2 or NVMe.



Barber Shop in Chinatown

 Nowadays I loathe to have my haircut, that's why I seldom have mine cut, maybe once or twice a year. I went back to Chinatown. I could ...
