I'm going to try the eye-fi card with the I pad and see how well it works together. I read some where you can do raw on the CP and jpeg on the SD card at the same time, which would be cool
yep or visa versa if you want the raws going over the eye-fi
i'm interested to hear how you go with the ipad link

Lighting / Re: 580 EX II problem retroreflective vest
« on: March 08, 2012, 11:02:20 PM »
In the above photo I'd have dialed in a +2 exposure compensation and reshot.  You can do the same thing shooting manual, but it will take longer.  For a "news" shot like this  I'd really ramp up the ISO, and try to capture as much ambient light as possible.  Shoot without the flash if you can, or as little as possible. 

Adding to the flash compensation is the wrong thing to do here.  The flash is causing the reflection.  If you could move the flash off camera a few feet, or bounce off something, that would have helped a great deal, but obviously is not ideal for quick shooting at an accident scene.

The camera is metering properly, but the retroreflective portions of the vests are much brighter  than the subjects making the camera.  The camera is averaging and overexposing the retro-r portions, underexposing everything else.

Also Joe mcnally has a section on exactly this in one of his books hotshoe diaries when he shot one of the NYFD guys after 911
its worth a read

I bought this set off ebay about $60

I did some test shots the other day vs bare flash and the softbox is not too bad
the little mini beauty dish is actually really cool
the softbox comes with white and different coloured covers too for if you want to use the ligths for effects and back lighting

the softbox is easy to assemble and disassemble and ridid, the mount that goes onto the speedlight is pretty good and sticks on nice and tight

the orb is amazing for lighting a wide area

over all its quite a cool little accessory kit for portable flash

while not a substitute for real light modifiers i can see them being handy in certain situations

I would not use the softbox for shooting a group outside though simply not enough power and spread of light
it would be ok for a portrait or couple shot

I would get a couple of speedlights on stands off camera through shoot through umbrellas either side of you
Thats what i use to shoot outdoor groups

2 yongnuo 565 and a set of radio poverty wizards or the yongnuo st-e2 controller for ir would work

Canon EF 100mm f/2.8L Macro IS.

Absolutely and it also makes a fantastic portrait lens

I've looked at the Hyperdrive and may end up getting one.
How is the interface? looks a little cluncky
I have resisted buying an Ipad In the hope that it would get USB host functionality. I am not ragging on apple, I use Macs, iphones etc but for me there is nothing the ipad does that my iphone cant so no point getting it.

The apple camera connection kit will allow you to download photos from a card to the ipad however there is no way to transfer those photos to an external hard drive (maybe the hyperdrive will work here, does anyone know if the hyper drive will work with an iphone?)

I would love to be able to shoot tethered to an ipad
I would love to be able to use the ipad for live view shooting

currently i can control my 5Dmk2 with my iphone and the dslrbot app but that does not have any live view shooting function as its all one way comms over IR

when travelling it would be great to be able to only take an ipad and a compact portable hard drive rather than a laptop. Maybe a macbook air is the best option instead

well hopefully i'l have my mark 3 on the 22nd march so i will be testing it side by side with my mark 2 :D

Any chance you could do a head to head RAW comparison of high ISO shot in marginal light?

Most of the ISO comparisons are shot in good light and to me they don't represent what to expect in truly low light shooting conditions.

I was planning on doing some twighlight city landscape shots side by side off tripods ISO 100 using cable release and 16-35f2.8L II should be reasonably marginal light with stretched dynamic range and represent the sort of scene that I find banding can really stand out if you push the shadows too hard

The 24-105 is a workhorse lens, very good quality, reasonably light and compact has great versitility and as others have said is probably the best General purpose lens. the 28-300L is possibly better but its 3 times the size and 2 and a half times the price

EOS Bodies / Re: Are you happy with the 5D III Specs?
« on: March 08, 2012, 06:32:00 PM »
I'm much more concerned with pattern noise and canon fixing that issue, than the difference between 22MP and 36MP the difference represents only about 20% increase in vertical an horizontal aspects and as MP increase the law of diminishing returns will become more and more apparent especially since there are trade off associated with those higher MP

Software & Accessories / Re: Monitor Calibration Tool
« on: March 08, 2012, 07:06:19 AM »
I used this method
for my dell u2711 as i read bad things about the expensive calibration tools not working for that monitor
so far I think its great in the adobe products but the web browsers look all screwy on it
overall I think the method worked well I found I reduced the brightness more before the calibration and i took a few goes at it until i was happy
since this method is free i suggest trying it before spending money :D

EOS Bodies / Re: Canon 7Dmk2 any rumors??
« on: March 08, 2012, 07:00:15 AM »
I think we should start sandbagging a levy here at canon rumors for when the 7D mk2 gets released at $2500+  to help stop the river of tears over the price :P

I have about a dozen of these
they are reasonable price and have never had a problem with any

usually write raw to the CF and jpg to the SD

With the increased high iso becoming available the requirement for IS is reduced. This is particularly true of the shorter lens where unintentional motion blur becomes more and more likely as shutter times increase. For an example a 24 mm lens shooting at 1/30 doesn't need IS - but will almost inevitably get motion blur. Put 2 stops IS on the lens and low and behold everyone starts shooting at 1/10 or slower - where even IS wont stop handshake translating into motion blur - and hoards of people start complaining about the quality of the image.

Factor in to that the pixel size and that smaller pixels typically require either a faster shutter or a more steady picture on the sensor.

For 35mm film, the accepted wisdom was that 1/focal-length-in-mm was the required shutter speed for a photo without blur. So a 300mm lens requires 1/320 or better. A 2 stop IS system potentially lets someone shoot at 1/80, hand held. Now that's 35mm film. If the sensor in your camera has twice the resolution of 35mm film then you'll need to double that. Thus there are those that say that if you are using a 5D Mark II, you need 1/2*focal-length-in-mm for a good shot. So a 300mm lens requires 1/600 hand held, but if you're using a 2-stop IS system, you're back around 1/150.

IS is required to offset the increase in MP density.

On my 5DII I stick to the basic rule which is the next stop faster than the focal length. For example the 135 f/2 at 1/200 gives sharp every time.

I think everyone is aware of the benefit of IS for longer lens - the issue being disussed is when IS falls down on short lens where handshake looks like motion blur. This is presumably why Canon didn't include IS on wa.
problem is that argument was fine until they released a bunch of slow expensive WA primes with IS

« on: March 07, 2012, 10:34:05 PM »
I have the L macro and its a brilliant lens very sharp great IS and nice and makes a really nice portrait lens too
It has fantastic colour

I love my 16-35 II distortion is a non issue as its easily corrected using lens correction
I also find vignetting is not that significant even on full frame

well hopefully i'l have my mark 3 on the 22nd march so i will be testing it side by side with my mark 2 :D
