Bottom: I chose to create an abstract background for this shot taken in a woodland in France. Top: I just had a small amount of beach hut wall to work with as a background so I opted to use a long focal length lens. These shots were both taken with the XF 50-140mm lens set to 140mm and f/2.8. The thing is, it’s all subjective and some people live razor thin DOF.ĥ. There is nothing in the background to ruin the shot. I should have stopped the lens down to f/5.6 for this shot to get Mischkah’s nose, lips and chin in focus too. The GF 110mm f/2 lens at f/2 has a very narrow depth of field of about 1cm when used close up like this. Bottom right: I’m not a fan of out of focus foregrounds but I don’t mind a mirror shot like this where it’s part of my principal subject that is out of focus.Ĥ. Top right: Close up shots have less depth of field than far away shots so expect to need a smaller aperture if you want your subject sharp front to back. I think I got away with this one but it’s not a look I particularly like. Left: Notice the shallow depth of field that f/2 gives. Early in my career as a wedding photographer when I shot weddings in less than beautiful locations I used a long lens for almost every shot. With a long focal length it is possible to completely isolate a background. These shots taken with the XF 90mm lens at f/2 could have been taken anywhere, in a studio or on location. To isolate a portrait from its background use a long focal length or tight lens. ![]() The depth of field is quite shallow and although the background is out of focus it is clearly adding to the picture. Notice how it pulls in the complete room for effect. This portrait was shot using the XF 14mm lens on an X-T1. In its extreme I use very wide lenses to include all the space that I’m in. To tell a story or set the scene in a portrait use a short focal length or wide lens. The shallow depth of field in this shot is not an issue because the narrative is more important than the detail. It needed to be clearly discernible yet not competing with the principle subject. Middle right: I shot this interior with the wider yet still telephoto GF 110mm lens to include a bit of the background. Top left, right and bottom left: GF 250mm lens at f/4 on the GFX50s. In that shot you can see a depth of field of about 1m that encompasses both barristers yet the background is nicely out of focus. Click on the picture to see the top left shot full size (Then pinch to zoom in). The long focal length takes care of the background while the f/4 aperture gives me about 50cm of depth of field to work with.ġ. I therefore set an aperture of f/4 on the GF 250mm lens. When I shoot a fashion collection like these Barristers gowns, I need enough depth of field to show the garments in sharp focus from front to back but I still want an out of focus background.The XF 56mm lens shot will include far less background because of its narrow angle of view of view and it will appear more blurred giving more separation from subject to background. The picture taken using the XF23mm lens will include more background due to the wider angle of view and the background will be easily identifiable. The perceived out of focusness (new word □ ) of the background is different however for the two shots in example 1.It might just happen to be from the tip of the persons nose to just in front of their ears but it will be the same for both lenses. That it, If I shot a head and shoulders portrait with the XF 23mm lens at f/2 from close up and matched the head and shoulders framing with the XF 56mm lens at the same f/2 from further back the depth of field in the subject will be the same. ![]()
