The Benefits of a Mobile Access Point

It could be argued that with modern Android phones offering to act as WIFI access points, there is no longer a need for the likes of the THREE WIFI pocket Access points, the successor to “WIFI dongles”.

three access pointMine has been sitting in my case doing nothing for the better part of a year and it is only by chance that I’ve never handed it back. I use my phone as an access point and that generally works well for my laptop and tablet.

But this week, all of that changed. We’re having a week off for the school holidays and my wife Maureen and I are in Cornwall, staying in a little cottage.  When we got here, the promised WIFI never padded out.

The building was split in two with the owners in one half and us in the other. The access point was in their half and the walls were just too much for the connection – in addition they have a limited connection and asked that we take it easy – that is just NOT what either of us do as we have so many gadgets that need WIFI for updates, browsing, email, watching video etc.

In addition we had friends with us both of whom spend much of their spare time on the web – such is the modern world. 

To make things worse, I’d just installed some cloud software on the phone which wanted to back up all 8,000 photos from the phone to the cloud – not to mention the usual numerous updates of Apps and laptop programs and operating system.

A part-time next-door WIFI was just not going to do it.

My first line of attack was to use my phone as an access point – after all it has 4G and I have an unlimited use contract with 3. Well, that option vanished as I realised I had almost no signal.

It was at this point I realised I still had the dongle-type unit in my bag, a black THREE-based unit able to share a 3G connection with several devices/ people at once. I switched it on and… nothing – months of lying around and the battery was utterly flat – but within 10 minutes of charging it had enough power to run and I was delighted to find FULL SIGNAL.

Unlike phones these gadgets are designed for no other purpose than to take in a 3G signal and re-broadcast as WIFI… and they do it very well, In addition I could stick it in a window for best signal. The unit gave access throughput the tiny cottage without any problems for the week, left charging 24-7 and requiring a reboot only once in the process (most likely due to too many gadgets trying to access it).

If I don’t use this again for a while, the unit has well and truly earned it’s keep. The weather down here has been and continues to be ATTROCIOUS and so we’ve spent slightly more time indoors than we expected. The continuous, high speed, reliable connection has been more than welcome.

The camera never Lies, or does it?

I should stress at the beginning that I am neither a doctor nor an optician so if I use the wrong terms, consider the source.

I have however been fascinated by photography since getting my first SLR in my very early teens. That was followed by a few years of hands covered in chemicals as I learned how it all worked. The move to digital was a no-brainer but offers so many possibilities.

They say “the camera never lies”.

There is a world of difference between the camera and your eye and I will use that to question the above statement.

When a camera takes a picture, let’s say outside in the brilliant sunlight (clearly not in the Northeast of England) with some trees and dark shadows, it records faithfully what it can… and therein lies the rub “what it can”. The camera stores images in memory. It stores 3 colours – red, green and blue and it stores them with a limited dynamic range – that is, the range from the lowest brilliance to the highest brilliance and that is FAR from complete.

So I will firstly argue that the camera DOES lie in that it does not show you the complete range from the darkest shadow to the brilliant sunlight.

That is the first flaw and though there are ways to improve this (RAW images contain more bits-per-point than JPG and HDR photos take multiple exposures to try to “cluge” a wide dynamic range picture) the result is far from perfect and the mechanism for displaying the image is also far from perfect as it, too is unable to display the brilliance of sunlight down to the darkness of the deepest shadows (we’re ignoring the fact that the image is flat rather than 3D – that’s another discussion).

But this is only the beginning.  When you use your EYES to look at a similar scene of high contrast, your eyes and brain cheat in many ways, NONE of which are replicated by the camera.

a) You see a combination of the truth and what you expect to see.

b) The individual sensors in your eyes can selectively desensitise to give you a non-linear image of wider dynamic range than a camera would manage

When you look at an image, your eyes do not work the same way that they do when looking at real life – because the image does not have the dynamic range from dark to light to trigger the same responses in the cells.

Don’t believe me? Do you squint when you see a photo of bright sunlight? No. If you look at a photo of darkness will more detail emerge the longer you look at it? No.

Beautiful piece by Matthew Sullivan in HDRSo when someone comes along with a beautiful HDR photo and the photographic “experts” complain about HDR not being “pure” it reminds me of the people who say that valves are best (generalisation – the old ways are best) – I find myself smiling.

I take photos with the best equipment I care to carry around (more often than not my S4 phone) and I use photo tools to render those images to as near as what I THOUGHT I saw or I WANTED to remember and that, at the end of the day is what matters – unless of course you’re selling the images and even then – the image on the right is nothing like reality – but it would still look lovely on a wall. A “pure” photo can never reproduce reality exactly – so treat the camera as an artistic tool and enjoy.

A note for Android lovers… if your phone gets updated to Lollipop (coming soon) – keep an eye out for “Camera FV-5” app – the author is promising RAW format images. If you have something like the Samsung S5 or similar phone with high grade camera – you’re in for a treat! RAW will allow a greater range of post-editing as there is more information to start with.

Life

Peter Scargill in SpainSince coming back from Galera in Spain in the summer, life has been hectic – Maureen went back to school for a while, was recently off again but is now back in action. Hollyberry Cottage has been packed but we managed one day to get some essential maintenance in. I’ve been to Brussels for meetings and managed to fit in a trip to the Mini-Europe, I’ve been back and forth to Blackpool for FSB meetings, visited Jodrell Bank, been on a cruise just off Guernsey and next week we’re taking a short trip to Cornwall to go see the Eden Project, something we’ve been meaning to do for years but somehow never gotten around to it. We will of course post pics in here and on Facebook – I’m just hoping we get something remotely like decent weather.

The rest of the time has been filled with day to day emails and phone calls. I’m sitting here surrounded by new technology, trying to get a little WIFI board working and my friend Jonathan has brought me a wonderful tiny blue display which we’re considering right now to be a wonderful idea like the laser was – magical product but what can you do with it – well we certainly found plenty of uses for the laser!

Of course no blog entry is complete without a decent size photo – so here’s a picture of breakfast at a wonderful little cafe in Bellingham – good healthy stuff.
