Which is they they’re usually doing the rim light thing I mentioned earlier. Strip softboxes are an unusual light source for many. But the same principles apply to all strip softboxes, regardless of brand or budget. As it’s a Profoto video, it’s not that much of a surprise. With a larger softbox, the edges may be completely blocked, effectively acting like a smaller softbox with a gradual vignette to the light.Neil uses Profoto RFi 1’圆′ and 1’x4′ gridded softboxes and Profoto B1 flash for this presentation. From across the room at say 3-4m, the whole of the softbox front will be clearly visible, but when you move right up close like a couple of feet away, light will pass freely through the centre of the grid, but towards the edges and corners the gaps will become progressively smaller. In a small studio with light-toned ceiling and walls, this spill will bounce around the room and back to the subject where it will lighten shadows quite noticeably (can be either a good or bad thing) Then fit the grid and check the greatly reduced pattern of spill, but also look directly at the softbox front. Theory and angles are one thing, but should be overlaid with some real world practise because both the environment and subject distance can change things a lot.Ī simple experiment is to stand the un-gridded softbox upright in the middle of the floor and note the extent of spill on the ceiling and walls. But if you wanted to isolate their effects you would want/need to put a large flag/divider between them. if you wanted to combine two softboxes to create a larger softbox for soft light (wrap) you would want them to overlap in the middle (at the subject) just as all of the smaller points overlap individually. if the spread/wrap isn't reaching the subject, then the grid absorbing it is irrelevant.Įdit: It might be easier to think of a grid as being an array of tiny flagged softboxes. Just as the loss of light due to using a grid varies with the distance it is used. If it is far enough away that the light reaching the subject is mostly parallel, then it will have little/no effect. But in order to see the difference the softbox has to be close enough to where the wrap characteristic would have affected the image to start with. The taller and tighter the grid is, the more affect it will have on the quality of light. The primary benefit of a grid is that it divides all of those light sources into smaller groupings and "snoots" them, this reduces the wrap angle of the light between them.
outdoors), but a grid still serves a purpose. In a large enough space that concern would be eliminated (i.e. the same can be achieved with flags or a recessed diffusion surface. The spill reduction you speak of is a rather small aspect of a grid.
you can mask a softbox to any size and it will still act like a softbox. And each of those smaller light sources has it's own fan of illumination. eg: people.Ĭould anyone give some advice on which I would get more use from.ģ0x120cm (11.8"x47.2") Strip Softbox With 5cm GridĪ key to understanding softboxes is in understanding that they don't really make your light source larger rather they break the light source up into a larger number of smaller light sources. So there are two sizes I was looking at and although the smaller looks great for a smaller space I was maybe thinking the larger one may have more uses. "Have a bit of cash from Birthdays to loose" In fact a few tenners from the Birthday before "old style" !!!!! On occasion I use clothes pegs to attach blocking material to make a strip box which works fine but I'm thinking a stritbox would be beneficial too and I'm sure they will be versatile. They have been great and have worked well. I own a few softboxes most of them bought on advice from you people on here. The guy used a a strip box which seemed very useful, he was using a speedlight which is fine as I use speedlights. That said I have seen a few videos lately on product photography. So like most I watch the various videos on the subject. I'm sure most on here know that I just enjoy photography and I take photos for fun/hobby.
