Hello all,

Can someone tell me what criteria for "Flash Fired" are evaluated to return a YES or NO answer in Affinity's Metadata column?

I'm using a Hasselblad 907C CFV 100 with remote studio flash fired by a radio transmitter. Sometimes I connect the transmitter to the camera's hot shoe, and sometimes via a sync cable (i.e., to the transmitter, not hotwired directly to the flash).

I know when the flash has fired in real-time, and, besides, it's easy to tell after the fact by looking at the image. I'd simply like to know why I always see "No" in the metadata and if there is a way to indicate that a flash was used.

I suppose this has something to do with TTL flash exposure adjustment, which I never use. But it sure would be nice if, somehow, the camera and the software registered the fact that the flash did indeed fire.

I think Affinity just reads existing metadata that are stored in the image file. Do you know that your images have the 'Flash' attribute set to 'On' or 'Yes' in their EXIF metadata? Does for instance the Phocus app show them as expected? Or the Exiftool?

Thanks for your reply, Thomoso.

Phocus software, unlike Affinity, does not indicate whether a flash was fired or not. I don't know if Photoshop or CaptureOne do, either. Regardless, other than manually entering one's IP info as metadata (e.g., copyright), the rest is just there in the RAW file as far as I know — generated automatically. So I'm still wondering what factors, if anything, with perhaps any other camera's RAW files, but not excluding the Hasselblad, are looked at by Affinity to determine and annotate if a flash fired or not.

I shoot a Canon, AP does register the flash firing or not. I've shot on camera hotshoe, remote wireless and TTL. Here's a screenshot of the EXIF Metadata on one of my images.

Same here. When I have a Canon flash mounted on my Canon camera hotshoe, the metadata in the file shows Flash fired: Yes. That shows up in Lightroom, Canon software and Affinity Photo.

When I have a 3rd party trigger mounted to the hotshoe (in my case, a RadioPopper), it sends a signal and fires a remote strobe with a compatible receiver, but Flash fired = No. It appears Canon does not recognize this as a Canon flash unit and writes Flash fired: No. to the metadata.

You might ask in the Phocus user forum or the Hasselblad support under what conditions the camera writes the wanted metadata.

Not so much. I shoot a Canon 70D, using Yongnuo Flashes, with the Yongnuo wireless trigger, with the flash mounted on a stand, with or without a softbox, and AP versions 1 to current Beta all report Flash Fired in the Metadata. Of course if I'm not using or have the flash shut off, then it reports the flash did not fire.

I guess whether the "Flash Fired" metadata field returns a "Yes" depends on the device mounted to the hotshoe. With a RadioPopper radio transmitter mounted to my Canon hotshoe, metadata records a "No" in the attached shot, which used an off-camera Canon Speedlight to light the subject.

Read my post above. I think your issue is with Radio Popper transmitters. I don't have that using my Yongnuo Flashes and transmitter.
