Third Party Manufacturers / Re: Tamron 70-200 f/2.8 Di VC USD Hands-On
« on: November 28, 2012, 08:52:00 PM »
I am actually very interested in this offering. I cannot afford the Canon's MKII and it's MK I (with IS) is not as sharp as the non-IS version. If this is sharper and has better color contrast than Canon's non-IS and Sigma's OS, I will probably pull the trigger on this. Having said that, if this was priced $1300 or less then it's a real winner.

Amazing feedback. Thanks folks. I have jotted them down on google maps for reference. Looks like my wife came up with similar points of interest. And really appreciate the advice on drinking and driving, I dont drink but I can't say the same for the other drivers that may be driving on those roads, so will keep that in mind. I had no idea, so thanks again for the heads up! You folks are awesome. ^_^

Landscape / Visiting Napa Valley. Need tips
« on: November 24, 2012, 03:35:03 AM »
Have a trip to the Napa Valley planned this weekend. I was hoping anyone here have any tip or advice on beautiful locations in and around Napa Valley that's worth exploring. I am looking to shoot some landscapes, and currently researching some options. It is going to be a day trip so would like to touch some must see places before heading back home.

Appreciate your help.

Interesting review of the Demb Flip-it!

Demb Flip-it Review

Wow, some really good inputs for everyone. Thanks neuro for the photos of the bad boy. Have you faced any AF assist issue since the softbox is partially blocking the assist beam senser on the flash unit?

Chris, I am looking at the Demb units Marsu42 has given links to. Which one are you using? Any photos taken with the Demb products would be cool, saw some samples on their websites and it looks pretty neat.

Lighting / Re: YN622C trigger experiences?
« on: November 21, 2012, 10:05:55 AM »
I recently purchased the YN622C triggers and I couldn't be any happier. At first I was going for the PW's flex and mini but that would have cost me around $350+ for the set. I knew about Yongnuo's RC622C transceivers but I wasn't sure if they'd do the same thing. I bought them off eBay for $79 and works perfectly. The operations are straight forward and very similar to the ones from Pixel Kings. Heck, in fact the designs are pretty similar.

Anyways, I have one mounted on camera, and another one has my speedlite 580 EXII attached to it which is off camera. You can access full flash menu right from your camera and control your speedlite from there through these YN622C transceivers. I like quality, not bad at all for something that's 1/4th the price of similar PW systems. I would have bought the Pixel King ones but they yet dont support 5DIII like the YN622C does. Both Pixel King and Yongnuos are made in China btw.

The bigger the light source, the softer the light.  A StoFen works well but is designed for bounce flash - it diffuses the light a bit, but doesn't soften it much or at all when used direct.  The LightSphere is a little bigger, and that means a little softer, but it still sends a lot of light up - lost power at best, and with low colored ceilings you'll get a color cast

One option that I've used successfully is a Lumiquest Softbox III - it has an 8x9" surface which provides decent softening of the direct flash. It's about the biggest modifier that you can attach to your flash head and still move around with it (as opposed to a light stand with remote triggering).  You'll still want to get it off-camera with a flash bracket and OC-E3-type cord.  If it would help, I can take a pic of the setup I'm talking about...

Neuroanatomist, that would be awesome if you could share a photo of the setup. I think that is exactly I would prefer on the flash head, a mini softbox that I can point directly at the subject off camera and yet pick up softer shadows. Thanks yet again for the suggestion.

I consider myself a hobbyist and have just gotten into flash photography, and I was hoping to seek some advice and recommendations on portable diffusers for the flash unit. I have a 580 EXII (Sto-fen diffuser attached on head) which at times I need to shoot on or off camera at birthday events or parties (indoors). The events are not professional shoots just family and friends throwing private events. At times circumstances forces me to shoot with minimal gear/equipment, I am usually shooting solo and moving around the venue quite a bit to capture candid shots of adults and kids. Having said that I wish i had something that could soften the shadows like you get when using a shoot through umbrella. But like I said, mobility is an issue for me.

I was checking out the videos and demos of Gary Fong's lightspheres. Are they any good in terms of softening the harshness of the shadows while at the same time illuminating the subject nicely? Few problem I often run into are high ceilings or non-white colored walls, hence cant bounce off off them. I am looking for a diffuser or anything that is practical and portable, preferably something that can be mounted on the flash head to take nice portrait shots at parties events mentioned above.

If it helps, I currently have a lightstand, 40" shoot through umbrella, a pair of radio triggers.

HDR - High Dynamic Range / Re: Problems with Noise in Dark Areas
« on: November 16, 2012, 03:21:48 AM »
HDR is best when it is used to achieve dynamic range the is IMPOSSIBLE with a single exposure, not just as an effect or detail enhancer.  Here is a shot I took a few weeks back that would literally be impossible without HDR or exposure fusion.  It is 7 AEB at 3EV per step.  Yes you heard that correctly, 18 EV spacing total.  My eyes could see it this way, but with a single exposure my camera couldn't.  HDR is as much an art as any other technique.  Use it, don't abuse it.

That's a beauty @!ex. Perfect use of HDR, keeping it as natural as possible.

Lenses / Re: Thinking about a 17-40 f4L USM. Thoughts?
« on: November 14, 2012, 11:28:35 AM »
Was wondering how big of a difference of 1mm really is between the 17mm of 17-40L lens and 16mm of the 16-35mm L lens.

Hope technology = significant improvements in sensor architecture and design

been seeing a lot of that from competing brands like Sony and Nikon, wait Nikon's using Sony's sensor right? So I guess it's just Sony??

Yes, as far as I know sensor technology is from Sony. Nikon is limited to provide electronics and software in addition to Sony's sensor. That must be fairly limiting on a development side (i.e. not to be able to design/control the entire setup), but Nikon is still able to provide something good in this situation, which is quite impressive.

For the Same sensor in Sony Cams and in Nikons... the Nikons seem to extract better DR and noise for the same analog sensor... Tells me Nikon's AD and amplification algo's are perhaps superior...

In some ways, Canon is like Intel... Nikon like AMD... AMD once beat Intel to the 1Ghz mark, caught it napping, because Intel was both arrogant and lazy... but then it came back with a Bang and AMD is still playing catch up after a decade... so there is precedence in the tech industry for catching up and reversing the lead. AMD is now slashing prices to make it's products interesting.... Nikon is already feeling the pressure and competatively pricing it's products trying to get back market share...

This year Nikon sensors have been good. Lets see what Canon brings to the table with the 0.18 uM process next year...

+1 on that analogy =D
