Black & White / Re: The TRI-X 'look'...
« on: March 07, 2014, 11:51:41 PM »
Real Tri-X from a 1989 trip to the Canadian Rockies. (Maybe not profound shots but they do give the feel.)   Scanned with a Plustek Optifilm 7400.

Mt. Spokane described it very thoroughly and eloquently.

For those that want it in a just a single picture, look at this graph:

Ouch.

EOS Bodies - For Stills / Re: 10D, 100D or 700D?
« on: December 12, 2013, 08:56:30 AM »
The Q menu and touch interface on the 100D and 700D are nice to help new users.   

This spring I was faced with a similar situation and tried to get my wife to use my backup 40D - she was intimidated by it.   We ended up with a 650D as the 100D was announced but not available at the time.  She likes it a lot and likes the video capabilities.   Unfortunately she keeps taking "my" 17-40L as she likes the feel of it over the 18-55.

It's still in the picture data embedded. If you open the file in a HEX editor you'll see several adobe comments, one of them is "Digital Camera Fine Pix X100 Ver1.30". :)

Or, if you don't have or want a Hex editor, there are browser plugins like "FxIF" for Firefox

Interestingly enough, it's not the camera model field, it's the "Software" field that says "Digital Camera FinePix X100 Ver1.30".

So the software stripped all identifiable info and then added identifiable info.

Third Party Manufacturers / Re: Appeal of Nikon Df
« on: November 11, 2013, 04:03:55 PM »
I voted "butt-ugly". 

At first glance, I saw the top of the camera and the retro knobs and had a brief "Oooh shiny" moment.   Then the rest of the camera sank in - too tall, too many buttons on the front, and the back has no retro at all.  (A 60D-esq pivoting screen should have been there so the user could have pretended they were time-traveling.)

Additionally, the newly released "retro-lens" has no retro to it.  Even Ken Rockwell, who proves daily with his web-site to have almost no design esthetic in him, chose a vintage lens for the picture candc cross posted.

Software & Accessories / Re: RAW to black and white

The camera's sensor is made up of sensels each sensing one of red, green or blue.  Placed in a grid of 4 sensels (2-green, 1-red, 1-blue).   Conceptually the value of the pixel is the value for each cluster of 4 pixels but the clusters are not unique, the pixel to the right is sharing half of it's sensels with the one to the left - and half with the one above, and half with the one below and half with the one to it's left. 
Peek at the picture at:

http://www.photozone.de/sensor-types

So you are getting a full resolution picture where the number of pixels in the picture equals the number of sensels on the sensor (less 1 column and 1 row of sensels to account for the edge condition.)

So the short answer is no - given a Bayer sensor, you can not get better resolution than you already are.   

Taken to an extreme. If you took a picture of a perfect red wall with your 5Diii - only 5.6 Million red sensels recorded into the raw file would have a value while the remaining 16.7 blue and green sensels would had no value.   It's the Bayer algorythm that lets that combination be interpreted as a consistent 23 Megapixel image of a red wall.

Don't forget the Photo Permit if you intend to use your photos or videos "for financial gain or public display and exhibition."

The Navaho Nation is one of the most financially depressed areas of the country and at times it can feel like the Tribe is trying to rectify that through its menu of fees.

EOS-M / Re: EOS M and Vintage Glass
« on: September 11, 2013, 10:19:30 AM »
Dustin, Everything is wonderful, my favorite is the yellow flower picture.

For the thread, here are two pictures I took of my daughter before and after a recent haircut using the EOS M with a Mamiya/Sekor 55mm f1.4 on an m42 adapter.  The soft focus is from manual prefocussing and not the lens.

Lenses / Re: Long telephoto prime lens for landscapes?
« on: September 04, 2013, 01:32:29 PM »
It can be difficult to use a long telephoto for landscapes.  The issues can sometimes be overcome.
1.  Haze in the air shows up easily, so you must time your shots to minimize it, such as early mornings.
 
2.  Heated air between you and the distant subject becomes more of a issue, once again, the solution is cold days or early mornings.
 
3.  Just the amount of air between you and the subject means that the resolution is going to suffer, so don't expect high resolution.
 
In some cases. its the only option, but I would not want to try it on a regular basis.
 
Here is one image of the Alki Point Lighthouse in West Seattle taken from a moving tour boat at 235mm with my 7D and 100-400mm L  on a cold and hazy day. I boosted the blues in pp perhaps too much because of all the gray.
 
I also tried to get a shot of Mt Rainier, but the hade overwhelmed it.  Even trying to bring it out in PP didn't reveal much.  Once again, the boosted blues to help the gray sky just colored the haze blue.  The Mt Rainier image was at 300mm.

...

The Mt Rainier shot could benefit from the "Lumosity Blend" technique Kieth goes over at NL to make the mountain stand out without boosting the sky or overly altering the color.

If you don't mind me posting an edit of your image I can show an example.

Quite a few 7D timings for various cards and firmwares on this thread:

And the 7D Rob Galbraith link is:

While Rob covers up to 1000x cards, it is on the 1.2 firmware version.

Your camera will likely have tests against a pretty extensive list of cards at Rob Galbraith's site:

EOS Bodies / Re: Wrecked my 6D today, what a POS
« on: July 27, 2013, 05:30:27 PM »
Don't forget to throw a silica-gel pack in the battery compartment.   

My s95 was inadvertently left out overnight, on the ground and went through storm that dumped an inch of rain in 30 minutes.   It was in a leather case that prevented the rain from directly striking the camera but acted as a big sponge.   I popped the battery and card, dried it off, and put it in a brown paper bag with rice and the silica-gel pack in the battery compartment for two days.  I didn't apply heat as I didn't want to drive moisture further into it - especially the lens.   It seems to have survived, and since it was face down, the lens doesn't seem contaminated.
