The already impressive\u00a0Profoto B1 flash<\/a> (B&H<\/a>\u00a0\/\u00a0Amazon<\/a>)<\/em>\u00a0became even more awesome in Dec 2014 when high-speed flash sync (HSS) capability was added through a firmware update.<\/p>\n The photo above was taken at 1\/2000 @ f\/1.4 @ 100 ISO. I wanted that super-shallow depth-of-field, and I wanted the light to be more flattering than you’d get from a bare speedlight. In this case, I used a\u00a0Profoto RFi 1’\u00d73′ softbox<\/a>\u00a0(affiliate),\u00a0<\/em>with the Profoto B1. (I kept both baffles on the softbox.)<\/p>\n The summary: it works!\u00a0But\u00a0there are a few minor limitations or quirks though that you have to be aware of. (More about this in the summary at the end of this article.)<\/p>\n <\/p>\n For the photo of Melanie<\/a> at the start of this article, I didn’t want any of the dappled sunlight on her. I just wanted the light from the softbox & Profoto B1 on her.\u00a0Crouching down low in the middle of the road, my car shaded the sunlight.<\/p>\n I used the\u00a0Sigma 50mm f\/1.4 DG<\/a>\u00a0here, since I knew I’d get crisp images, even wide open. Check out the\u00a0review: Sigma 50mm f\/1.4 ART lens<\/a>\u00a0to see just how well it performs.<\/p>\n <\/p>\n <\/p>\n The winter sun coming through the barren trees next to the side of the road, made for a stark backdrop. I wanted that f\/1.4 aperture again to isolate her from what could’ve been visual clutter at a smaller aperture. Here I pulled the power down on the Profoto B1 to level 8 so I wouldn’t over-expose. I had to pull the light a bit further back to make sure the flash exposure was good.<\/p>\n <\/p>\n <\/p>\n The Profoto B1 is now a formidable portable light source for any photographer who shoots on location. There are a few quirks\u00a0with the Profoto B1 in high-speed flash sync:<\/p>\n Even with these few limitations and things you’d have to adjust for, the\u00a0Profoto B1 500Ws AirTTL flash<\/a>\u00a0(affiliate<\/em>) has\u00a0now been\u00a0improved to the point where it truly is an exceptional on-location light.<\/p>\n <\/p>\n <\/p>\n As one would expect from a flash that goes in to high-speed flash sync, there is a linear change in output as the shutter speed is pushed up. For every stop over 1\/500th and up, the output drops by a stop. This is discussed thoroughly in the high-speed flash sync tutorial<\/a>, and in my book, Off-Camera Flash Photography<\/a>.<\/p>\n With the Profoto B1, there is an approximate 2-stop light loss initially as the flash goes into HSS mode. Just as you go from 1\/250th to 1\/500. (Or whatever your camera’s max flash sync speed might be.)<\/p>\n However, this actually means only a 1-stop loss in practice. The homework part – figure out why a 2 stop light loss only means 1 stop change when used on location with bright ambient light?<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" High-speed flash sync (HSS) with the Profoto B1 flash The already impressive\u00a0Profoto B1 flash (B&H\u00a0\/\u00a0Amazon)\u00a0became even more awesome in Dec 2014 when high-speed flash sync (HSS) capability was added through a firmware update.
