Re: HDMI without an Alpha?

Thanks guys, plenty of food for thought here. I'm going to have to hunker down and digest it slowly. For the record, my Sony Vaio can manage up to 1366 x 768 and as someone pointed out, certainly can't accommodate another graphics card. I haven't yet bought a tv. My budget runs to $A2000 which is ab...

Re: Wireless flash question

Ah, thanks David, you cleared that up for me. I had assumed that the preflash for the purpose of exposure measurement came only from the built-in flash. From your answer I infer that the built-in flash need only be powerful enough to trigger the remote flash, which then emits a preflash for exposure...

Re: Wireless flash question

Hmm, hadn't thought about the extra distance involved in flash to brolly. You're right, with the flash at 1.5 m and bouncing off a silver umbrella at say 0.5 m away, total distance is indeed 2.5 m from the flash head. I didn't know that the built-in flash normally delivers 1/16 power. Is this 1/16 o...

Re: Wireless flash question

Thanks David for your informative reply. Can you explain one more thing? I don't understand how the umbrella can alter the ratio of built-in flash to off-camera flash. Regardless of the attenutation by the umbrella, is the HVL 42 not instructed by the camera to increase its output till the camera se...

Re: Software for Creating Photo Collages or Layouts?

If you haven't made up your mind yet, I suggest you look at Fotofusion by Lumapix.com. They offer three versions, from free to photographer level to studio level and it's excellent. I've used the middle version for a couple of years now and find it does everything I need, both for my own albums and ...

Re: HDMI without an Alpha?

Thanks for the link. However I should have stated my needs more explicitly. I'm looking for a way to get the same quality on the tv as I see when I connect my Sony A700 to a Sony tv via hdmi. From my pc the Avermedia will accept only analogue input, and I'm guessing that the conversion from digital ...

HDMI without an Alpha?

Re: Wireless flash question

Yes, you surmise correctly. The on-camera flash alone provides what looks like sufficient illumination while still firing the 42. However the camera is not telling the on-camera flash to provide stand-alone illumination as otherwise putting fabric in front of it would not diminish its output. Rather...

Wireless flash question

Hi all, newbie here. I'm using my A700 and HVL 42AM flash for portraits and can't balance the lighting as I'd like to. I have the flash operating wirelessly, illuminating the subject from one side through an umbrella. My problem is that the on-camera flash which triggers the HVL is providing fuil il...
