<p>Hello,</p> <p>I recently purchased the PROFOTO B2 KIT. It comes with the AIR remote, which is basically a flash trigger remote that fits the flash socket of the camera. This remote trigger supports TTL.<br> So far it had been working great but last night I wanted to take group shots at a reception diner and something was totally wrong. <strong>My shots were all dramatically underexposed, although I had the TTL mode enabled on the remote</strong>. I was under pressure and in the end I decided not to use the B2 Kit and I just used high ISO. The photos don't look great.... <br> Today, I finally understood what was wrong: on the <strong>5D MK III</strong>, there is a setting '<strong>External Speedlite control</strong>'. And then 'Flash function settings' where you can swith from ETTL to M, change first curtain vs second curtain and finally <strong>change the exposure compensation.</strong><br> <strong><br /></strong>Although changing from ETTL to M is reflected on the remote display of the B2, changin exposure compensation is absolutely not displayed so unless you look at this (hidden) setting in the camera, you have NO WAY to know that you are using exposure compensation.<br> It turns out that mine was set to -3, hence the under-exposed shots ! <br> <strong>My question is simple : what could explain this setting was set to -3, knowing I did not change it myself ?</strong> In my opinion this should not even be enabled when using external flash - especially considering I'm not using speedlites ! <br> <strong> </strong></p>

<p>sure, but that wouldn't give the wanted effect (blurred windmill) </p>

<p>Thank you for your responses, they were all very useful.<br> I think combining two exposures in this case and creating a composite is the way to go :)</p>

<p>I see. So basically at this time of the day, there is no way to achieve this effect, right ? <br> Sounds like an impossible shot :) But at least now I know the B2 is not the problem.</p> <p>Thank you.</p>

<p>Hello,</p> <p>I am novice with the Profoto B2 and strobist in general. Today I wanted to try and combine a long exposure with the use of the flash.</p> <p>The picture below was taken at 1/10s, f8, ISO 200. This is to achieve the blur effect in the windmill. However I wanted myself to be sharp and the profoto head was placed about two meters in front of me, with no modifier, just the bare head at full power. </p> <p>My question is: why am I completely blurred ? I though the flash should have frozen the movement but it's not the case. Any idea what to change ? <br> I just want to mention that I've used a ND6 filter to get that low speed, but I don't think that should affect the flash...</p> <p><img src="https://quvr1g-ch3302.files.1drv.com/y3mQjSCoTHlIrFTI91S79ztkAIvffiCFU_gkj10h_qWQWBnJmFp_W83UB5-52UmR3wzOTbT7E5jguU-hDlDqmlCS6Z4K51X97P3C84cAhjTl_Bv_sTzMl_jzex3yxKKuPcDkSE6Ov556ZaHlfMLdD2v3qkN052p1JolL0bV7czG9FE?width=660&height=440&cropmode=none" alt="" width="660" height="440" /></p> <p> </p>
