Travelling light – Part II on the field

Disclaimer: there are many USB power banks on sale however most of them do not declare the maximum output current and therefore you cannot be sure that it will work in all situations I describe. The equipment I use does work and is proven by my daily experience, the suggestions are not prescriptive but if you choose your own parts you do do at your own risk

It has been some time since my post on chargers and recharge facilities. During the pandemic I have done a considerable amount of land based photography including wildlife, landscape and astrophotography so I have had the opportunity to develop the concept of portability further on the field. So I wanted to share my experience with you all as some of the findings are beneficial in every day situation.

Charging your camera battery

Today some cameras can charge the battery in camera using USB. In almost all cases the camera needs to be turned off to allow charging, as a complete recharge of your battery can take a few hours I never use this method. I always rely on spare batteries typically 3 and a dual battery charger that can be powered using USB. I use Newmova they are cheap and cheerful for both my Panasonic and Olympus cameras.

With 3 batteries you can have two in the charger if needed and one in the camera which means uninterrupted shooting for a long period of time depending on your use.

Battery Grips

I also use battery grips in particular for my Olympus camera. Battery grip provide the most benefit when you are not wanting to interrupt shooting while swapping batteries. I usually set the camera to use the grip battery first and the camera as back up which means you can then insert another battery in the grip and keep shooting. I do not recommend using a battery grip as a sole source of power as at the end you can can go through 2 batteries relatively fast if you use quick burst shooting. The other dis-benefit of the grip is the one battery is always locked inside the camera so you need to increase your total battery stock to 4 if you use a dual charger. The grip is very useful to shoot verticals and provide weather sealing but overall is not my favourite option and I only use it for specific session on my Olympus camera because I only have 2 batteries.

There are some working 3rd party battery grip like this one that function AS LONG AS YOU USE ORIGINAL OEM BATTERIES.

I have not seen versions for Olympus camera and the original battery grip is expensive. I got mine second hand for a good price.

Again if you only have two batteries or you want to rotate 4 batteries a battery grip is a good option if you don’t mind the extra weight.

Power Banks

I use a relatively simple USB power bank as I do not have PD capable cameras. This power bank has a decent capacity but more importantly it can output 4.5A using two outlets.

This power bank has also a light included very useful for your night photography. You can also use it to charge your phone but with two outlets means you can power two dual USB chargers and effectively charge 4 batteries twice until it runs out (typical battery less than 2000 mAh).

This power bank can also be used as constant power supply for cameras that take a dummy battery and do not support powering through USB.

Using the power bank with this fake battery kit means I can run my GH5 in video for days (8.72x batteries equivalent charge).

IT IS VERY IMPORTANT THAT YOUR POWER BANK OUTPUTS MORE THAN 3A OTHERWISE IF YOU USE MECHANICAL SHUTTER THE CAMERA MAY GO IN SHUTTER VIBRATION AND SUFFER PERMANENT DAMAGE

Some well know power bank from respectable brands like anker and even rawpower themselves only outputs 3A current total so when the mechanical shutter is used and the camera draws more current you run into issue. This also happens when you set a custom white balance and the camera triggers the mechanical shutter. So if you have such power bank you are limited and hence I do not recommend them.

If you also use flash you can use the same chargers I already linked in the previous article

Prices have dropped to £7.99 for the micro USB and £9.99 for the dual USB C and micro USB input. Note that despite the misleading description the two chargers are identical except one has micro USB and the other also USB-C. The USB-C version is slightly bigger (70x90x23 mm USB version vs 97x114x34mm USB C). The USB C version has a stronger output for AAA batteries that I do not use and it does not charge faster standard AA so don’t be mislead.

Dew Heaters

Another useful accessory if you do astrophotography in humid or cold environment is a lens warmer. There are two versions I recommend the one with the temperature regulator as the strip gets to 50 C and this can increase dark current noise in your shots.

beyond underwater imaging

It is now almost one year since Covid-19 lockdown in UK and a bit more since my business travel has stopped. Next week I will getting my Covid-19 first vaccine jab but we do not yet have full clarity about the implications on leisure and business travel. The various countries are dealing with the pandemic with different degrees of speed and effectiveness and it is possible that some of the most exotic diving destinations will be on the allowed travel list later than western countries.

Many people have discovered local diving out of necessity and some have also done underwater photography in their bath, however for me this was not sufficient.

Since last year I formally joined a photography club and looked at expanding my interests. In 2020 as I have been staying at home I have taken the highest number of photos to date.

At beginning I thought: how can I reuse some of my camera lenses I use underwater on land? Mostly this was about macro in the garden. Slugs, bees and flowers were part of the first part of the journey.

I soon realised the skillset was similar but not identical and there were specific requirements to be fulfilled.

I then moved into abstract tried some portraits and more night photography. I needed to start investing in more lenses as I was getting more specialised and improving in the task.

I also started some bird photography in the garden using feeders to entice little birds. This proved challenging but I discovered I much more preferred predators and larger birds so I started going on walks locally to photography red kites. I already had a long lens so with a teleconverter started getting better at photographing birds in flight.

All of this has been done locally without the need to travel.

After a short summer break, where I got to do some diving re-discovering the beauty of Sorrento peninsula and the amazing diving on the coast, it was time to get back to England with the somewhat grim prospect of a very dire winter in full lockdown.

And then something happened thanks to the friends of the New City Photographic society I discovered an amazing location on my door step.

Woburn Abbey and deer park owned by the Duke of Bedford and spanning across the towns of Woburn and Ridgmont.

I went there the first time in November and literally fell in love with the location. After many early morning rise and many pictures taken I decided it was time for a video project.

Deer are sufficiently large that are not too difficult to film compared to birds and are extremely rewarding as they tend to stare at you.

The winter season has been an opportunity also for late sunrise which meant not so early wake up calls to get there for the golden hour.

Now that we are coming to the end of the full lockdown scheduled for March 29th I have decided to release a short film to remember what it was during this period and the magic moments I had the privilege to experience mostly on my own in the Woburn Deer Park.

The film will be released on my YouTube channel on Friday 26th of March at 8PM GMT. To make it easier to digest I will upload it in separate parts and if possible as a whole. YouTube is being very slow to process footage in the last months so I hope it will be all up next week.

I hope you will enjoy it. It is a total of 26 minutes of duration out of around 2 TB of video material collected in the months of January, February and March 2021. I will be putting posts on how it was shot in case you also want to expand your horizons…
