The Young Ones - Arwen by Okavanga The Young Ones - Big Ears by Okavanga…

What a dreary, dull, damp and dismal Sunday morning! Rain and heavy cloud! What can you do on such a dispiriting day? Look for some photographs of course and play with them to make pretty images! Panic attack - the file containing the shots I have in mind is not to be found in Lightroom - why not? The catalogue says they are there, but they're not showing - imminent meltdown of catastrophic proportions!!! I blame Brexit, climate change, the Government, meowing cats, banging doors...Oops, they are filed on a different Drive! Panic over... Brexit not so bad, climate change over-egged, meowing cat is adorable, but the Government still sucks and doors are still banging.

Here are three shots taken last February in London at night with my Canon EOS M. With shutter speeds of about 1/10th second and ISO up at 6400, the originals look woeful - blurred, distorted and oddly angled. The odd angles arose from the three pints of London Pride consumed in a local hostelry, but there is not much you can do about the dark. Nevertheless, software can conjure up some magic. I've used Nik's (now Google's) Colour Efex Pro software and a filter therein called Midnight to make virtue out of necessity by softening and colour toning the originals, previously cropped in Lightroom to remove the odd angles. I thinks they are OK, I hope you do as well.

OMG MOAR POEMS!  for the collection!
fotoponono Featured By Owner 1 day ago
thanks for the collection, David!  I poked my nose and read your remarks to BrettA.....and the truth that, "only men can understand how to use a camera without the instruction book".  Without 'ganging-up' against women, I fully agree and FULLY supportive of your take.Sherlock Holmes

I guess that we're both in bother now, Henry!

Thanks for the fave, David!  Well, we couldn't wait until tax returns and went out and bought Darlene a Canon 5DS R--with a 50.6 megapixel sensor!  She's still working though the guide that came with it.  Someday, if I behave myself, she might let me borrow it!
Okavanga Featured By Owner 1 day ago
Wow! Flashing green with envy! That is going to be hard but enjoyable work to get to know and use. If I were Darlene I would be setting up a tariff for other users, especially a husband. OTOH, as we men know, only men can understand how to use a camera without the instruction book, so I expect you will be consulted.

I have bought the new Canon EOS M5 mirrorless camera and am awaiting delivery tomorrow. It has had a generally favourable press, and I've been well pleased with the original EOS M that I bought several years ago. But, compared to your, or rather Darlene's, new heavyweight it is but a trifle!

Look forward to seeing the output.


BrettAZimmerman Featured By Owner 1 day ago  Hobbyist Photographer
We've kicked around the idea of the mirrorless camera, for sure.  That's the up, and the down, side of this hobby--always something out there that's desirable.  As for Darlene's new toy, that's probably close to the upper limit in terms of cameras one would want to take "into the field"; anything beyond that is likely in the $15,000 range and up--like what the late Leonard Nimoy was using for his studio work.  Next, better lenses might be the way to go--but, for cripe's sake, I hope not for a long time!

As for your--I suspect, facetious--suggestion that men don't use instruction books, Darlene learns that stuff faster than I do, which is one reason I bought the camera for her and not me--so she could go to the trouble of learning the thing so she could teach ME.  (lol)

Here's Darlene's first image with the new toy:

Stunning output for sure, Brett. The potential for detail must be enhanced over what we 20 Megapixel impoverished guys can do.

"Facetious", now there's a word I haven't heard for quite a while - a good one at that though. I think it has acquired a bit of a darker tone on this side of the pond from the idea of witty, tongue-in-cheek connotations that it used to have. Indeed, I recall being called a facetious fellow, on occasion, when a student! A facetious remark over here now is tantamount to being an inappropriate comment or ill-judged humour. I certainly hope my comment was not seen in that light - a mere tease on Man's unfailing desire to show superiority of knowledge over the fairer sex when, in reality, exposing his incompetence! :laughing:

Good point about the taking expensive gear into the field. When I add up what I take on vacation, I blanch at the potential loss. Yet, I read in a book on bird photography, that the author had about $20,000 of gear with him on a shoot - lenses, cameras, accessories. We need to take security very seriously.
