Photography Technique / Re: DOF, Infinity focus and Hyperfocal distance
« on: December 08, 2014, 05:15:46 PM »
Another thing to consider is that most lenses designed for auto-focus, focus beyond infinity.

Focusing using hyperfocal distance, or focusing at infinity is best done with a manual lens.

Check out the DOFmaster link that Surapon provided and you might want to read this:

http://www.cambridgeincolour.com/tutorials/hyperfocal-distance.htm

Thanks. I read both. I am not clear but infinity focus and Hyperfocal distance seem to be two different things. Using the link and the calculator:

Full Frame sensor
F8, Focal length: 40mm
Focus distance: 500m
It calculates to 6.17m as nearest acceptable sharpness and infinity as the farthest.

Now,
The focus distance is probably hard to estimate for a landscape shot. So am I not focussing at roughly 6.17 m to get this large DOF or am I focussing at 500m to get that? And what if my focus distance of 500m is totally off?

Hi,
Thanks for all the replies. Here is where it started. I had posted an image, given below. It's acceptable but when zoomed in, not tack sharp or at least ALL of it which this image demands. Live view won't work(low light, long exposure etc) with Auto Focus but only with MF in this light. I need to improve my technique. Here is the link to the image and the picture information. I am going there to take the shot again.

ISO 200, F14, 38mm and 20 sec shot on tripod with cable release straight out of camera, no post at all.

What I learn:
Switch to MF with live view
Perhaps F8-11 rather than F14 or higher
Try and get everything in focus using infinity focus

What I have changed:
- Lens has been upgraded to version II of the 24-70 F/2.8
- Tripod is much sturdier with RRS

So,
to do it right am I doing:
- Composing it the way I like
-Turning the lens to MF and then turn the focus ring to infinity?
And I should have quite a wide DOF and sharpness I desire?
I probably sound naive, sorry. Thanks for your critique and help.

Photography Technique / Re: Live View and Remote release
« on: December 06, 2014, 06:40:08 PM »
I tested this today again. I thought that this should only happen in low light. It was a cloudy day but reasonable light I think but the same happened. The remote release will trip the shutter only in MF. I would have thought that with adequate light this shouldn't happen. I will have to cheek this again in bright sunshine but is this something that you have observed too?

Hi,
Can someone please explain how these work? I understand Depth of field but not the others. What is the theory behind them and how to use them practically? And then any App for the iPhone that is easy to use? Thanks,
Ray

Photography Technique / Live View and Remote release
« on: December 05, 2014, 06:26:02 PM »
Hello All,
I had posted my trouble in this thread.
http://www.canonrumors.com/forum/index.php?topic=22495.0

And since then I have seen one other person saying the same. I tried all the suggestions that you nice folks had suggested but still the same outcome. Except jdramirez. I didn't try what he/she suggested till today and you bet that was the issue. I still couldn't be sure so ….
 I called Vello, absolutely no help. They said I should buy another wireless remote which is on sale!!
Then I called Canon. They said that in Live View(irrespective of AF mode, quick or live) remotes won't work as the sensor is hunting to focus. But, if I switch the lens to MF then it would and this is what I found while playing with it again prior to calling them!!! They say that likely in low light the camera is unable to focus without the focus point that is active while shooting through the viewfinder. So neither the camera nor the Remote release is malfunctioning. Thought I'd let folks know so others might benefit from this.
 Thanks,
Ray

Software & Accessories / Re: Tripods - CF or Aluminum...?
« on: December 05, 2014, 01:09:25 PM »
Any suggestions for the adjustable cord/strap?
Use a shoe lace. It's always good to have an extra one and strong enough to put a few kilos of weight on the tripod

That would be one hell of a shoe lace to reach up over 6ft when the tripod is fully extended!  ;)

If one were to consider a CFRP tripod, I think it should come with an equipment hook on the underside to hang your bag for added weight.  But then you have to worry about your bag swinging in the wind.

Good CF tripods have a bag hook.  Simply attach your bag via an adjustable cord/strap so the bag rests on the ground with the tension of the weight on the cord - stable legs, no swinging bag. 

In actual wind, the modestly additional weight of aluminum legs is unlikely to provide enough stability in any case, I'd hang a bag from either type of legs.

Any suggestions for the adjustable cord/strap?

Photography Technique / Re: Night Shot- Brooklyn Bridge
« on: December 04, 2014, 07:56:23 AM »
Your pictures are very good. I especially like the 3rd and 4th one. I do have other shots when I moved right and left. Also, barcketted some exposures in RAW. Somehow I picked this one first to review and was discouraged to see that there might have been some blur. Coming weekend I intend to work on the images and take the suggestions made on this thread. This was such an amazing spot! I went to shoot the Brooklyn Bridge but turn around and the Manhattan Bridge was also equally amazing shot! Next time I would shoot this scene from the Brooklyn tower of the Manhattan bridge which will avoid most of the water and give an elevated perspective of the Brooklyn Bridge with Manhattan skyline behind it. Thanks for your insight.


When I was last in New York, I walked the Manhattan Bridge to Brooklyn and the Brooklyn Bridge to Manhattan (kind of backward, but whatever).  Of course, with camera and tripod.  I remember a lot of vibration on the Manhattan Bridge and ended up increasing ISO and hand holding shots of the Brooklyn Bridge because of the motion.  Something to think about, especially for night shots.

Will do. Last time this shot was taken from DUMBO, beneath the Manhattan bridge. When I saw it back home I felt taking it from the Manhattan bridge would give it a different and perhaps better and certainly elevated perspective. It might also be possible to avoid a lot of the water as well. As you mention, I also plan to walk across both the bridges and get different perspectives. I also felt that despite the Brooklyn Bridge's obvious attraction the Manhattan bridge is awesome too! In fact I like my pictures of Manhattan Bridge much better. However, the romance of the Brooklyn Bridge is eternal. Thanks for your suggestions.

Ray, I think it's a nice photo and given the water, it's not an easy shot to pull off, but the exposure looks great.  It's nice and sharp, too, and the blur looks like motion blur in the cables, at least to my eye.  If it were me, I'd crop out most of the bottom to make it a panoramic as the shore and water don't add much.  I'd also crop out the building on the far right as it looks crooked and again, doesn't add to the shot.

In terms of the carousel, I think it adds some character to an otherwise familiar shot.  If I were there, I might even try to make it the focus of the shot.  I read somewhere that if you can't exclude something from a shot, you should work with it instead of trying to work against it.

Also, and I'm betting you did this as well, with this type of scene, I'll usually try to work a number of different shots in, if I have time.  I did that in Jacksonville, FL, shooting a similar scene.  It's something I learned to do when I started taking on paid work.  You can never have too many options for a client :):



The mist ruined a whole sequence I had near the fountain, but this is just an example:






This might be a silly question. If I were to crop out the water to make it appear like a panoramic picture, how do I do it? Just take the crop tool and crop out or do I have to keep a particular aspect ratio in mind? Thanks

Since I was somewhat dissatisfied with this shot I plan to go back in the next couple of weeks to do it again. Besides suggesting a better technique do you have other stuuf I could/should photograph after dark? Though I'll be there for sometime during the daytime also so feel free to suggest. Thanks,
Ray

Landscape / Re: Give me your Mountains...lol
« on: November 21, 2014, 09:19:17 AM »
Good afternoon everyone.

Here in Washington State, actually - closer to Portland, Or, we're blessed with having several mountains in such proximity.  Anyways...I wanted to share a couple of mountain photographs I took since moving here. 

If you have any of your own, please feel free to post them.  Oh...and I threw in a waterfall one. 

See if you can guess its name.
Beautiful shots. Have never been there so could you tell me their names? Thanks,
Ray

Street & City / Re: Famous icons in your city
« on: November 17, 2014, 08:29:08 AM »
I like this thread, so I hope more people will post icons from their respective home cities and countries. Makes you want to travel :)

This is the Monolith, made by Gustav Vigeland, one of the most famous sculptures in his park. The column is over 14 metres tall and carved in one single stone. It consists of 121 human figures. There have been many interpretations of the Monolith: Man's resurrection, the struggle for existence, Man's yearning for spiritual spheres, the transcendence of everyday life and cyclic repetition.

The Vigeland Park, or Frognerparken, is the largest park in Europe, with sculptures made by one man, 212 in total, made in bronze and granite. (You´ll find some more over at the Zeiss Otus 85/1.4 thread).

1DX, Zeiss Otus 85mm/1.4
1/2000s, f1.4, ISO100

Very nice!

Those are all great shots.  Just got back from Rome and had some great photo ops.  This was actually taken accidentally in jpeg, so it left me limited ability to pp.  I think it still came out fairly nice as the sky allowed some great colors.

Absolutely stunning!
