Photography Technique / How to Expose and get sharp Focus of Moon
« on: January 07, 2015, 12:32:36 PM »
I am taking the first shots with my new 100-400 II and decided to try it out on last night's full moon (1/6/2015). 

I used my 7D +100-400 II mounted on a sturdy tripod.  I shot against the dark sky at 400mm to get maximum image size (FF equivalent 640 mm).

Since moonlight is reflected sunlight, a typical daytime exposure ought to work fine.  I shot in manual mode using 1/100 sec at f/11 and ISO 200.    This exposure seemed OK, but maybe not optimum?

My trouble was in getting the focus right to get images with the sharpest possible detail.

I used manual focus in live view magnified 10x.  I took each shot using the camera 10-sec self-timer and cable release to minimize camera shake.   

I was disappointed in the lack of detail of my images.   But maybe I had unrealistic expectations and have done about as good as can be expected within the limitations of my equipment - definitely no telescope available.  :)

Still the attached uncropped image shows craters at 10 o'clock that I definitely cannot see from the ground!!  So this is an improvement over my own eyesight!!

I'm looking for feedback from others who have taken shots of the moon using equipment similar to mine.  Did you get better images than my attached sample.   If so, what were your procedures?

Any feedback welcome and appreciated.


Lenses / PDF of users guide for new 100-400 II available on canon website
« on: December 17, 2014, 03:32:24 PM »

A PDF version of the users guide for the new 100-400 II is now available on Canon website   :D [size=78%] [/size]

Just got my new 100-400 II from Amazon.  Contacted RRS about an arca-swiss lens plate specifically for the new 100-400 ii.  They do not have specific plans for custom plate and suggested their MPR-113 instead.

I'm interested in other alternatives that would allow me to mount the 100-400 securely on RRS tripod/release clamp via arc-swiss-style mount.

Any suggestions...?   :)

Photography Technique / Combining HDR and Panorama Stitching
« on: December 20, 2013, 12:51:31 PM »
Interested in hearing about experiences with panorama stitching combined with HDR.   What is your workflow?

I have shot my HDRs at each pano position first, then did HDR processing for each position (using Photomatix Pro), then stitched the resulting TIFFs into pano image using PS6.   

I get mixed results.   Any suggestions?

Software & Accessories / Lightning Trigger for Canon
« on: September 24, 2013, 05:18:07 PM »
Does anyone have experience with lightning trigger units for Canon that attach to the hot shoe?  See several models on the Amazon website, but no user comments that usually accompany a product add.  Feedback about your favorite model and pros/cons would be appreciated :)

Software & Accessories / CF-SD adapters
« on: April 11, 2013, 02:13:47 PM »
Has anyone had experience with CF-SD adapter card like these?

Is it intended for in-camera use, or for interfacing between CF card reader and computer?

If usable in camera, could be less expensive way to have higher capacity cards in cameras that use CF cards.

Is there a loss of write speed if used in camera with CF card?   What may be some of the other pitfalls? ???

For my 5D MkIII, I've tried to create camera settings for HDR mode and store them in the Custom Shooting Mode (C1, C2, C3).   It appears that Custom Shooting Mode is greyed out (cannot be selected).  Could not find anything in user's guide that addresses this.

By contrast, settings for the very similar AEB shooting mode can be stored in C1, C2, or C3. 

Has anyone tried storing HDR settings in 5D MkIII?  Were you successful? How?

If this option is not allowed, why might that be?  Could firmware be changed to allow this?


5D MK III Sample Images / Japanese Maple at Night in Available Light
« on: September 24, 2012, 02:38:05 PM »
Took on tripod with 5D3 + 100 f/2.8L macro in available light - lit by a small ground spotlight below the leaves. 

Shot manually at ISO 400, f/7.1 at 1.0 sec.   

My first attempt at this and want to try more available (night) light shots of these leaves.

Any ideas?

Canon EF Zoom Lenses / Canon EF 70-300mm f/4.5-5.6 DO IS USM
« on: September 21, 2012, 06:52:39 PM »
Pictures of Shuttle Endeavor on 9/21/2012 as it takes its victory lap over Los Angeles before final landing at LAX to begin grooming for a permanent place in the California Science Center.  These shots were taken as the shuttle flew over NASA's Jet Propulsion Lab near Pasadena. Exciting sight as it flew overhead at 1500 ft!  :)

Pictures taken with Canon 7D + Canon EF 70-300 f/4.5-5.6 DO IS USM.  Shuttle#1 is uncropped, taken at 300mm (480mm crop) at 1/400 sec, f/8, ISO 100.  Shuttle#2 is cropped, with same exposure, except shutter speed was 1/640 sec.   Both images shot in RAW using AI Servo and high-burst option.

Lenses / Just got new 17-40 f/4L packed with "EF lens" CD
« on: September 21, 2012, 01:47:50 PM »
Just got my new 17-40 f/4L lens to add wide angle capability for my 5D3.  Now I can go wider than the 24-105 f/4L kit lens.  Looking forward to running AF MA tests to see how it performs. 

A first for me: the 17-40 was packed with a "EF lens" CD that has PDFs of user's guides for all Canon EF lenses.  Saves Canon from publishing handy booklet size guide that can be easily stashed in my camera bag.  Lens User Guides don't always have much in-depth info, except for speciality lens, like macro, tilt, etc.  With PDF substitute, not as convenient as booklet size I've gotten with my previous lens purchases.  Another cost-savings move by Canon.

Macro / Tulip with 7D and 100 f.4L macro
« on: August 27, 2012, 08:07:35 PM »
Shot in available light on tripod with 7D and 100mm f/2.8L macro.  ISO 100, f/32, 1.3 sec,

Four images of Navy's Blue Angels taken with Canon 5D Mark III and 24-105 f/4L.  Each image shot at 105 mm with the same exposure settings:  ISO 800, f/8, 1/3200 sec.  Really enjoyed the Airshow and satisfied with results even though limited by 105 mm max focal length.    :)

My understanding is that STM lenses offer quieter focusing for video and the new T4i is apparently compatible with STM lenses for this purpose.  Is this also true for the 5D3?  The 5D3 user's manual makes no mention of STM.  If 5D3 not compatible, can firmware update make it compatible?

For those of you that have already received your new 5D3, what version of the firmware does it have?  Expecting my 5D3 on 4/2.

Looking for a quality quick release camera strap that attaches to camera body like the Canon stock strap does.  That is, with a fabric connection to the camera NOT a metal connector that will soon rub the finish off the camera body.   

Thanks for any suggestions?  Please provide brand and model number if possible.
