Software & Accessories / Re: laptop for tethered shooting?
« on: Today at 10:56:39 AM »


Only quirk I find lacking is that iPAD won't provide EXIF that you can see easily.
I'm looking for an iPAD application that can display EXIF, perhaps someone here can suggest several we can try out.

For those using an iPad to shoot tethered via WiFi what are the downsides? Is it perfect 100% of the time there must be some problems?

thanks again,

Both photos are great!
Very cute for the first one.
I had to giggle at the second one, just so adorable.

Do you have to turn off back button focus settings with CamRanger? I'm intrigued for macro shooting.

No need for that.  If you read the CamRanger website, the section on "live view" indicates that you can select the focus point of the scene from the iPAD.  Fine focus can be done, too, with the iPAD.
CamRanger is a real versatile aid/tool for macro photography.

Look at my photo posted on http://www.canonrumors.com/forum/index.php?topic=20914.msg413371#msg413371, reply 25.

Any UV system generates ozone, with accelerates decomposition of rubber or many polymers.  The attack is worse than the drying of the gasket material.  Don't use UV, chlorox ect., to prevent fungal growth.
Most household moisture level is well over 50-60 percent, and fungal is still minimal.
I bought some plastic boxes, like the one you can get at big box store, the orange, grey/blue hardware stores, and the big blue discount grocery super store, so I can organize my gear and external disk drives.  I am sort of having second thought of the idea.  Coupled up in the sealed boxes, the air gets stale and things can grow inside with little moisture.  So, I keep the lid skewed, just to get circulation.
Someone on another thread got a drawer set for gear storage.  I think that is a wonderful idea.  Keeps dust out, moisture level at comfort range, and cool.  Rather inexpensive, to boot.

One question or concern:
If the environment is too dry where you store your gear, will it over-dry the seals, specifically, the O-rings, foam shock absorbers, etc., so they'll crack or disintegrate too soon?  There must be a range of humidity where fungal growth is inhibited without the gaskets getting too dried, thus too much desiccant can't be good.

I like my iPAD, retina, 256 gB RAM.  It holds over 1500 photos, with space to spare with large .jpg from 5D3.  YMMV., with programs installed.
For remote tethering, I use CamRanger connected with WiFi., a bit slow because of the communication between camera and CamRanger.  (Read about other features a out CamRanger from their website).  Nice about the setup is that I can show my subjects the photos I shoot, and I get feedback from them.
I use PhotoGene to quickly do minor .jpg adjustment.  Haven't tried to import nor edit RAW with iPAD.
This combination has allowed me to travel abroad and do some portraits works.
MacBook Pro do have more computing power, but really cost too much just used for tethering.
Really regret that your laptop got stolen.
Best of luck.

Lovely images!
Hope the harrowing experience with the night hike won't stop you from future excursions!  Just bring a red filtered flash light (torch) to help you see, without spoiling the night vision too much.
Your M with a couple lenses should be good gear for photos.

You certainly live in a place with lots of exotic birds, not to mention a great collection of gear.
Please keep us fascinated by your beautiful photos!

That's the idea.  Camera held by tripod ( I used a focus rail ), selected a portion of my object to photograph and focused on it with my CamRanger and iPAD and trip the shutter.  Then I moved my rail mounted camera a small distance without refocusing again, the focus plain is moved by that distance I moved the rail.  Remote release the shutter.  Repeat until the object is photographed front to back.

However, when I stacked my images, the resultant photo was totally in a blur!
The experts here suggested a stationary camera, and focus of different planes will be achieved by changing the camera's focus rather than moving the camera.  Something to do in this weekend while my orchids are still in bloom.

Thanks for the advices, Manace, Marsu and Tolusina!
I'll have to do some more tests.  I should try to shoot several frames with and without rails.

I built a focus rail and shot about 20 frames but the result that came out processed with PS CS5 was incorrect.  PS chose all the OOF frames and thus what I got was a 100% blurry photo.

My question to the experts here, when you use a rail to select a focus plane, will the image in front of the selected plane be slightly larger because the camera/lens is closer and the image behind the selected plane be smaller, so as you change positions during the process, what would happen to the stacked end product photo?
Conversely, if the camera/lens is held stationary, and the focus is selected by adjusting the lens focusing mechanism, what will be the result?

My setup: 5D3 with remote flash mounted on hot shoe, 100 mm_f/2.8 with Kenko extension ring, and the camera is controlled with CamRanger all mounted with a screw operated rail.

Thanks for the advice.
