John - your effort (above) is more aesthetically pleasing on the eye as the "original" image 2, which I found to be so blue as to be perceived as "unnatural". The purple mist just behind the boat is a bit too strong, but given what you were working from, it is (IMO) a reasonable "trade-off".

UHS is just an acromyn for Ultra-High Speed, and I believe it's measuring quicker read/write speeds in nanoseconds. If you are uploading perhaps 100 photos, you wont notice anything, but if you were uploading into the 1,000's, you'd begin to see a difference.

Is the 133x card possibly a higher class rating? I've got myself a couple of Pretec Class 16's rated at 567x, but I've found that it's only when the cards are used in a 3.0 usb card slot that you truly notice a difference in the R/W speed.

Possibly the reason vor the price variance is demand in the marketplace.

I agree with Andrew - No.1!!.. Image 2 is too blue and a bit "un-natural" for my liking.

Peter - I though it was NIKON that made colonoscopy equipment, not Pentax??!!

Why go to all that bother, Mike??.. Did you learn nothing from watching Val Singleton knocking all sorts of things up with sticky-back plastic, washing-up liquid bottles, and inner cardboard tubes from a toilet roll??

I appreciate that, Algi...

If I were to post you links to several ACTUAL INCIDENCES, you'd be scared to ever fly again - believe me!! These incedences all occured due to lack of compliance with the IATA/ICAO regulations, might I add!!

Algi - it's not so much whether or not a battery/batteries are charged, it's more to do with chemical reaction when in contact with outside forces, whether that be OXIDISERS that spontaneously combust when in contact with air/water, etc or presents any other hazard.

Remember the ValueJet disaster in the Florida Everglades about 10-12 years back?.. The cause of that was out-of-date oxygen generators (the kind that supplies emergency air supplies on aircraft) that were not packed in accordance with these regulations, and the chemicals reacted when the generators were activated in the hold because they had not been secured. The hold caught fire, and oxygen generators being oxygen generators, they provided the very thing that any fire needs to keep burning... OXYGEN! This is why these regulations have to be stringent.

That's just it, Dave... If there's any doubts as to the condition of the batteries, then they must be carried on board as cabin baggage, in order to minimise risk of potential damage in the cargo hold. That way, the airline still retains the right to lose your luggage, but you retain the right to take your Pentax gear into the cabin with you - a fair "trade-off", wouldn't you say??

Yeah - basically, Dave, so long as there is no possibility of a complete circuit being made with any conductive materials it "should" be okay. At the moment, it's all on paper - we'll be given practical briefings (from a cargo perspective) on how batteries should be packed and presented to the airlines. On top of this palaver, we also have to check the casings/overpack of any batteries/cells for signs of damage prior to packaging and certification of these items. Passenger is a different beast to courier/freight, but in essence passengers are "expected" to display a degree of commonsense with these items. Effectively, from Jan 1st, it is advisable to let the check-in staff know about any electrical/electronic gadgets you are carrying aboard an aircraft. If they tell you that it's ok, then the onus is on them if and when things are not as should be.
