Photography Technique / Re: Clouds
« on: September 13, 2014, 08:41:19 PM »
Any advice on how to get the most detail out of clouds?

Expose to the right, focus at infinity, stop down to your sharpest aperture and try to focus on an area that has relatively low contrast. HDR makes everyone feel free to go nuts, but any decent landscape photographer knows that the best light isn't sunset, it's just after... "Flat" lighting can be your friend. Exposing for the foreground and clouds is tough so just go with clouds if you want clouds, or if you're lucky enough that they meter in the same range (or the sky is dimmer!) go nuts with foreground. For this of course I use my spot meter (sekonic because I can't afford pentax).

If the cloud cover is evenly lit, awesome. If not, you can use a long lens and isolate one part so the scene DR isn't too crazy, then crank up the contrast in post.
If the shadows are darker than you want, you should try Magic Lantern. The Dual ISO should help. ML is very stable. I have it permanently on my 5D3.

Hi rpt.
Was your light a studio light, are they that much more efficient than halogen floods?
I had to use three 500W floodlights like this
http://quickbit.co.uk/site-lights-task-lights-portable-floodlight
A twin stand from above left and a single (the same as the link) below right just to get the recommended light level, as recommended by FoCal. I would reinforce that you need the light level they recommend as a minimum in my experience, I was only just above their level.

Cheers, Graham.

Macguyver's post is perfect! I had problems with my 100-400L too. Some of it was due to insufficient or varying light. So I decided to do all my calibrations at night. I light up the target that is pasted to a piece of plywood with a 500watt light. I also learned quickly not to raise the central column in order to maintain stability.

If these two do not solve your problem, may be take it over to Canon... All the best.
Yup, my halogen light looked like that. Well, without the stand...
No money or use for studio lights. I mainly shoot birds and bugs and flowers and scenery (mostly sunrise/sunset). The halogen is from the time I had a party in the garden :)
I kept moving the halogen closer to the target until I got the right light level.

You might find this post I wrote a while back helpful:

Thanks.  very helpful.  On 70D (my wife's camera) my 70-300 was profiled easily  while her 100-400 has caused nothing but problems.  I may bring this lens into canon to get them to check it over

Mr Bean, would you mind letting me know what ISO that image was taken at?
I am going to hazard a guess - Me thinks >= ISO 8000

Hey taxi :)
I had exactly the same problem with the 100mm macro. I suppose you've been shooting on OneShot AF handheld? In macro, only 3mm shaking, which is perfectly normal, can make the whole picture blurry. Try Servo AF, it will work much better ;)
+1!!!

I presumed it was on a tripod. Please do let us know.

I purchased Focal. I have Magic Lantern on my 5D3 but have not tried dot tune.

Hope this helps... Let me know if you have any questions.

Hi rpt,

I've tried dot-tune but the results were too variable and unreliable for me. Ever since purchasing Focal, I haven't looked back.

In the absence of Focal, manual empirical testing with different AFMA values is the best solution in my opinion. But it isn't easy to identify the sharp/sharper/sharpest photos using this method.
OK, Thanks. Having heard that, I am not going to test it in a hurry and my expectations are not high. :)

Have you AFMAed your lens? That may be the problem. Try live view focusing also - other than manual as rwmson suggested.

Hi, what is AFMAed?
I didn't use manual focus, I center AF point, it should be the most sensitive AF point, but the image came out wrongly focused.

This is an article by neuro. This should help. You can look for "dot tune" on the Magic Lantern site http://www.magiclantern.fm and also look up focalweb/.

India/Asia added!   :)  Been on the road.  Travelling.  I'm glad everyone is enjoying the thread!

Great Job, Dear Rusty----How about Russia, Egypt And Africa ?
Have a great day, Sir.

Oki-Doki - Just got back in town.   :D   I added Russia and Africa.  (Egypt is on the African continent so...)
Thanks Rusty!

After reading through a bunch of the comments here, I'm bound to say that we photographers are an easy crowd to please.
Put us in an ant-infested, humid rain-forest, and we'll exclaim "Look at those rich green tones and the glistening, sparkly water droplets!"; put us high on top of a mountain and we scout for bluish colours at the horizon, snowy ridges in the distance and condors sailing above us; try to get rid of us by tossing us off at the closest city dump, and we will reach for our macros and crawl around looking for small containers with interesting forms of mold in them; and when they finally hauls us off dressed up in that stylish canvas-jacket with fashionable leather straps on the back and puts us in a vaguely lit, bland room with gray concrete walls, then we would caress those walls, sigh and grunt "Ah!! Textures! If only I had my extension tubes..."

We can be happy in every place of the world. :)

RustyTheGeek, could you add India/Asia to your list?

Stock focusing screens with split prism and microprism collar.  I don't know that I'd really need/want one today, but I do sort of miss them.  :)
