You are using too many photo editors, I suggest you stick to just one as they develop photographs differently.

That was worth spending the time to read your post, it was full of very interesting information.
I have been using M43 cameras for many years now and still do, I have an Olympus EM10 and a Panasonic GX7, they both fit in my small camera bag with all the accessories I need. I have a 20mm prime lens permanently attached to the Panny and a medium zoom on the Olympus, both lenses are Panasonic.
On the whole, I prefer the Olympus but there is really not that much difference between the two although battery life is not so good on the Panasonic.

MPB.com is a UK company based in Brighton and now have a base in the US. I have used them many times and have never experienced a problem. MPB is a genuine company offering excellent prices and very quick delivery.
MPB is 100% reliable quite unlike some of the US used camera equipment I have heard about, so go ahead and spend your money with them.

Google is a wonderful thing, this took me about 30 seconds!!

I use a photo booth as seen in most supermarkets, it's cheap, quick and legal.

Chromebooks are not really suitable for photo editing especially RAW, I suggest you use Jpeg for shooting so then you can use "Snapseed" to develop your photographs.

Hi RG, that is a lovely photograph considering the poor lighting, I have developed your photograph which suits my personal preferences, so hope you like the outcome.

This is a list of changes I made:
Exposure reduced very slightly.
Lighting reduced by an amount enough to remove highlights in the cloud.
Shadows increased very slightly.
Whitepoint increased to improve white (brighter) areas.
Blackpoint lowered very slightly improve black areas.
Clarity increased to improve contrast slightly.
Dehaze increased slightly to improve cloudy areas.
Saturation and vibrance increased slightly to improve clour generally especially in green areas.
Sharpening increased slightly.
There was some noise in the upper half of the photograph so I applied some very slight noise reduction.

Beautiful photograph Bill, I have left it on my screen so I can keep looking at it. In the centre distance there is a white van parked, so can you camp there if you want.

I try my best to get the horizon level especially with seascapes but there are always some photos which still are not level. Recently I was stood on some sloping land and this made it even harder to get a level horizon. I do use a thirds grid and this does really does help, with horizontal and vertical lines.
The real annoyance is the amount of image which could be lost in more extreme cases.

I always use Scan Computers, they have good prices and reasonable delivery charges.

Great photograph Bill, I am trying to place the location because it seems very familiar, I was wondering if it was Wrea Green.

I pay £28 monthly for Virgin Cable TV and the Internet for that I have over 110 mbps and hundreds of TV channels which will soon include Amazon Prime for a year.

9999 is a lot of images, on my camera I can have a letter prefix which precedes the file number so can have up to 260000 (if required) which will keep me going for a while, the only thing is to remember to change the prefix on time.

I use prefixes to indicate which camera has taken which picture in my case I use an "M" for my Olympus and a "P" for my Panasonic.
Before you ask why "M" for the Olympus and not "O" it's because "O" looks like a zero which is not a letter.

Once again California is experiencing terrible forest fires destroying homes, farms and businesses leaving behind a trail of damage affecting 1000's of residents
I feel very sorry for what is happening to our US friends but I cannot understand how the authorities allow houses built of wood are erected in a forest which regularly has these awful forest fires.
Why are the Electric Power companies permitted to erect power lines at such a low level so that sparks ignite the trees?
Here in the UK power lines are suspended from pylons which are 50 meters high and sparking is very unusual, in the US it seems the power supplies are of very poor quality if sparking is a regular occurrence, the power companies obviously know this is a problem so they shut the power off.

That's a bit harsh on someone who's education is somewhat lacking in quality, it can happen to all of us including you TOMCAT! there is no such word as "misspelled" the correct word is "misspelt"
I use "Grammarly" all the time just in case I spell a word incorrectly.
