anybody know an easy way to get exif data into a form such that it could be put in a DB, graphed, etc....something that takes a collection of photos and makes a csv or something
Choosing the right lens
It looks like you have a pretty solid range of focal lengths covering everything from 11mm through 200mm. Not a bad set of lenses to work with. One thing that should be noted is that lugging around all that gear might get tiresome after a while, so you might want to think...
^--- I hope people can read this and understand where I am coming from when I argue about everyone debating what should and should not be allowed, what should and should not be on or off topic, etc.
When I come across a question like this, I instantly start thinking about how I can ANSWER it and HELP THE ASKER.
Then...I see the comments...debating whether it is a worthy question, whether it should simply be closed as a duplicate, whether it is actually off topic...or just sitting there musing about whether any of the answers will be useful.
I know EVERY single one of you who commented has more than enough skill to actually answer that question better than I did.
People are rarely articulate....most people have a hard time figuring out how to formulate a "perfect question"....rarely are people as perfectly spoken as an actor in a movie or on a TV show.
"I'm an amateur still learning everytime I use my camera so my question might sound basic but in what situation/landmarks should I use these lenses when in Paris? Also, any tips on using my new ultra wide angle lens would be appreciated."
I'm an amateur....
so, the guy doesn't know much, if anything
"What situations/landmarks should I use these lenses"
Thats not asking what to shoot...its asking how to know which lens to use when shooting around paris
"Any tips on using my new ultra-wide angle lens would be appreciated"
@jrista right, and I don't know that...I can't tell him what landmarks in Paris you can shoot with what lens.....I don't know how close you can get to the Tower or what style of a photo he wants
no, thats a seperate question...he's got..."what lens do I shoot what landmark with?" basically and "how do I use my wide angle" - which was basically just asked
@rfusca Sure you could. "You can use a wide angle lens to capture the full Eiffel Tower up close, stretching out to the sky above you, while still capturing its base"
I guess I don't see whats wrong with offering the guy something like that
is that really wrong?
to ask for an exemplar? and is it also wrong to actually offer a specific example of an actual use of his exact lens in an exact scenario?
@jrista I don't think its wrong, but I certainly don't think its useful. You can stick nearly every landmark in place of the eiffel tower in your sentence
@jrista right, but you could then rephrase it..."you could get far back with a telephoto"...or "you could get medium close with a normal lens"...I just don't think thats helpful
@jrista thats just the way I read it...i wasn't trying to NOT help the guy...I just don't see how we can answer the question I thought he was trying to ask
thats why the SE is what it is...there are so many different people that just because I read the Q one way and didn't think it was answerable doesn't dictate that its closed....somebody else (you) thought it was ok and answered it. Thats the beauty of the system and why we still need dissent among the ranks to keep things moving
Ok, so I totally misread the question.
Bulb mode, get your exposure right for the stars behind. Once you have this, set the shutter open for the required time, put the lens cap on / something over the lens (you'll have to count the time, the shutter needs to stay open).
Have your girlfriend sta...
Thats an interesting technique....bulb mode, cap, position person, flash
personally, I'm glad that everybody doesn't agree all the time. And that @mattdm brings up way he thinks it can be improved (even when he's shot down). It keeps it moving and not stagnant
This is Mr.Timothy Rogers,I write to confirm if you receive my first email about your late uncle's fund of US$27,846.00.19 Million Dollars in the bank?
"Second, it is very difficult to get an accurate focus with these lenses, especially when you are trying to focus on a star or planet that is barely visible in the viewfinder. However, I think this can be overcome with practice, and the short exposure shots actually looked like focus was pretty close, if not dead on."
that may not really be a special case
its pretty difficult to focus with any lens in total darkness
Ya, i was reading an article earlier....apparently Pentax pioneered most of the features of SLR's we're used to. Basic layout, TTL metering, autofocus, etc...they just feel behind once it went digital
been trying to catchup, but they're still doing some crazy things in advancing though. Like they're really doing neat stuff with the ability to move the sensor.
Not just the IS in body, but the astro tracking, auto horizon leveling, fine adjustments for macro work, etc
their IS even apparently compensates up/down,left/right, and rotational
there are astro focusing programs that download a series of shots at different focuses and then tell you which was the most in focus- but its hard to get back to that point
The Bahtinov mask is a device used to accurately focus astronomical telescopes.
It is named after its inventor Pavel Bahtinov. Accurate focusing of telescopes and astrographs is particularly of concern to those involved in astrophotography.
The mask consists of three separate grids, positioned in such a way that the grids produce three angled diffraction spikes at the focal plane of the instrument for each bright image element (star). As the instrument's focus is changed the central spike appears to move from one side of the star to the other. In reality, all three spikes move but the ...
grumbles i accidentally soldered a 100k ohm resistor in a 10k spot on my last try and its too difficult where it is to remove. Trying again tonight prolly, I'm in no rush - I don't even have a camera right now...its still in the mail towards Adorama.
took me like 3 hours to figure out that it was that though
they quoted over the phone around 70%, which is just under the craigslist ad and it would be super nice to get rid of all of it...so they asked to quote it in person and they would pay for the shipping and insurance to get it there
i'm hoping they'll keep that quote and I can get a lil' more out of them in a trade/store credit towards a k-5
we'll just have to see. It'll be towards the end of next week before I know for sure
