michael_kravit Posted June 24, 2003 Share Posted June 24, 2003 At first glance, Keith Carters images appear to be examples of depth of field studies. However, upon closer examination, his selective focus is placed precisely where he wants it and is either vertically or horizontally placed. He states that he uses a Hasselblad SLR. I would assume that this excludes the Flexbody so tilt and swing is not being used to obtain this selective dof (Focus). Additionally, his images are silver darkroom prints and not Photoshopped images. The two Hassy notches on the left side of his images are in sharp focus so I assume that he is not doing the selective focus in the darkroom by any easel or enlarger head swing or tilt. If he is truly using a Hassy SLR, does anyone have any idea how Keith is obtaining such a look? I can easily accomplish this effect on my 6x9/4x5 view camera, but am baffled as to his technique on the Hasselblad. Link to comment Share on other sites More sharing options...
ward Posted June 24, 2003 Share Posted June 24, 2003 I have never seen his work before today, and just did a google search to find some images; so I am no expert! My guess would be with filters, maybe with smudges of gel on glass. Isn't there a cokin variant that comes with a sheet of glass and tubes of various gels for selective blurring? I agree they are intriguing images. Thanks for raising the name. Link to comment Share on other sites More sharing options...
d._diehl Posted June 24, 2003 Share Posted June 24, 2003 I know this has been discussed here before; he's using a Hasselblad (Flexbody I believe) which tilts the lens causing the focus to range from sharp to very soft. This is recorded on the film, therefore the edge of the film, notches, etc. are sharp. It is an "in camera" technique. He probably does a little manipulation when printing (dodge & burn), but the bulk of it was created when the shutter was released. Link to comment Share on other sites More sharing options...
beau 1664876222 Posted June 24, 2003 Share Posted June 24, 2003 Here's a guy who's doing a similar thing, but better in my opinion: http://marktucker.com an explanation of his heavily home-modified Hasselblad: http://marktucker.com/plungercam/index.html Link to comment Share on other sites More sharing options...
ellis_vener_photography Posted June 24, 2003 Share Posted June 24, 2003 Maybe, just maybe, Keith is not using a lens --in the traditional sense of how most photographers define a camera lens -- on his camera? Have you thought of calling him and asking him? He lives in Beaumont, Texas. Link to comment Share on other sites More sharing options...
squareframe Posted June 24, 2003 Share Posted June 24, 2003 Keith Carter uses a Hasselblad Flexbody and 80mm lens. the Flexbody allows you to tilt the film magazine back, therefore creating a narrow region of focus. I have elaborated on this technique previously, so please check the archives. it will provide you with some interesting reading. Keith is a wonderfully accomplished printmaker and a very creative human being. check his website to see some of his newest work with photograms.<br><br> <a href="http://www.keithcarterphotographs.com">Keith Carter Photographs</a> Link to comment Share on other sites More sharing options...
squareframe Posted June 24, 2003 Share Posted June 24, 2003 Michael, if you are still interested in this technique, email me, and I will put together some of the materials I have from Keith's workshop I attended in San Miguel de Allende and Herminia Dosal's sensitive Flexbody efforts.

lawrence_title Posted June 24, 2003 Share Posted June 24, 2003 As has been already pointed out, Keith Carter's selective focus images have been produced in camera using a Hasselblad flexbody and are not done with filters or Photoshop. Given the the two stage process of taking a photograph with a flexbody, it is amazing that he has been able to produce some of his beautiful images of living subjects. I am sure that Daniel can attest that Keith has super mastered the technique to quickly execute the flexbody, yet I wonder how many of his shots are staged ? Rumor has it he can even use the flexbody as a handheld camera ? When you see his work in person, the other interesting thing is his selective toning of his silver prints. I was tempted to recently buy one of his recent images two umbrellas, as his pricing is still reasonable. Some may say this selective focus thing is getting overdone. While Carter and Dosal use the flexbody, there are few photographers that I have discovered that are doing similar interesting selective focus with a view camera: Olivo Barbieri: search Barbieri on: http://www.photoeye.com/indexbookstore.html and Claudio Edinger (Rio portofolio: http://musariumgalleries.sitebuild21.com/rio/index.html . I have played around with the idea of a flexbody, but I was inspired by Mark Tucker's work and his plungercam and I subsequently built my own version of his lens by duct taping a Rodenstock 6x6 loupe to a drilled out hasselblad body cap. The selective focus that I can create with this lens is unfortunately not a precise as what you can accomplish with a flexbody or view camera. Yet, my lens can use the incamera metering of my 202FA and is handholdable for shoot and run selective focus effects: <br><img src="/photodb/image-display?photo_id=1365818&size=md" height=752 width=752 hspace=10> Link to comment Share on other sites More sharing options...

derek_stanton2 Posted June 25, 2003 Share Posted June 25, 2003 Nice work, Lawrence. I read recently of someone else who had duct-taped a Rodenstock 6x6 loupe to some other component for the same purpose. I'm now tempted to try it myself. Does the tape allow you to manipulate the 'focused' area? I'd appreciate more information about how much of the lens cap you had to remove.... Did you just leave enough of it to maintain the security of the lens mount and give you a surface for tape? Also, (has this been mentioned?) a company called Zoerk makes an expensive lens accessory that allows similar effects. Thank you all. Link to comment Share on other sites More sharing options...
lawrence_title Posted June 25, 2003 Share Posted June 25, 2003 Thanks Derek. I think it was me that you recently read about duct taping a loupe lens, as you had commented on my chateau versailles picture last month. However, Mark Tucker was the one who invented the concept and design of his "plungercam": http:// marktucker.com/plungercam/index.html . In his history page he describes the first version had the loupe duct taped to the camera and eventually he went to a rubber funnel barrel. I believe Frank Ward who knew Mark also played around with this at some point: http://www.amherst.edu/~fmward/plungercam.html . Intrigued by Mark's images with the plungercam (check his Chicago/Atlanta pix), I went and bought a Calumet (made by Rodenstock but cheaper: $129 USD) 6x6 3X loupe. I had to break the plastic apron to get the loupe lens and barrel out of the apron. I then shortened the plastic barrel attached to the loupe. For the body cap, I completely drilled out my Hasselblad body cap right to the mounting flange using a Dremel tool and sanded it smooth. Then using black opaque duct tape, I made a funnel like barrel to attach the loupe (approx 2" diameter) and its metal/plastic barrel to the body cap (approx 2.75" diameter). In version one, the barrel was about 1" from the end of the body cap to the loupe lens. I doubled up the duct tape, so that no sticky tape was exposed that could attract dust etc., except where I was fastening the tape to the outside of the body cap and to the loupe on the other end. I used more duct tape to secure the loupe in the duct tape barrel. To focus this sucker, you would either push or pull the loupe lens in or out towards the film plane. Unfortuanately, with this set up I could not focus easily on anything more than 10 or 15 ' without having to push the loupe all the way in towards the mirror box of the camera. A few times, the mirror would hit the lens on its way up, which made me uncomfortable. On the advice of others on photo.net, I purchased an antique Zeiss Distar 3 diverging push-on filter (51mm: $15 USD) which increased the effective focal lens of the lens so I could now focus at infinity without pushing the loupe all the way into the camera's mirror box. So, I duct taped the diverging lens on top of the barrel containing the loupe. I also had to make the duct tape barrel longer (close to 2" long) to adjust to the new focal length of the combined loupe and diverging lens. As well, as advised by Mark I got a 55 to 62mm step up ring which I duct taped to the Distar diverging filter so that I could use color filters or ND filters. As I like 400 film, the ND filters are essential for taking outdoor pictures in bright light as the aperture is probably around 2 on this thing. Usually I need 0.6 or 0.9 ND to take pictures in bright light with 400 film. Now with this 2nd version, to focus I first push or pull the loupe out so that it is focused on the area of interest. Then to adjust the degree of selective focus, I can tilt the camera body (film plane) relative to the loupe (while maintaining the position of the loupe manually), or I can tilt the loupe plane or raise or lower the loupe relative to the body until I am happy with the positioning of the area of focus and the degree of blur etc. Then, when you shoot you have to maintain the positioning of the loupe to keep the area of interest in focus. Examples of it's use are in my surrealBrussels folder. The only thing is I learned on a trip to Brussels, that the duct taped lens can be a problem at airport security and I was almost not allowed to board the plane with it unless I was willing to unwrap the tape. Ironically, they told me I should have packed the item in my checked baggage as it was suspicious ???? Now, I always pack it in my checked bags. Email if you have other questions.

derek_stanton2 Posted June 25, 2003 Share Posted June 25, 2003 Don't know if i'm ambitious enough to try that myself. Perhaps i'll just sit back and admire the results of others.... Your comprehensive instructions, though, are very much appreciated. Link to comment Share on other sites More sharing options...
triblett_lungre_thurd Posted June 25, 2003 Share Posted June 25, 2003 folks, best way to learn these techniques is to buy a view cam and begin composing on the ground glass as michael hinted. then introduce some radical moves and refocus. it's not as hard as you think, in truth, it's quiet a bit easier than the opposite(scheimpflug). 'selective focus' wreaks faddish to me and definitely smacks of assbackward logic considering the equipment used. not inspired by sally mann, me Link to comment Share on other sites More sharing options...
joe_fertitta Posted December 12, 2010 Share Posted December 12, 2010 <p>I'm guessing that no one on here has read Michael's question. He has already said that he assumes that it excludes the Flexbody, which everyone is referring to. He even said that he can easily achieve this with his 6x9/4x5 view camera. I have the same question as to how he did this with a Hasselblad SLR, Keith Carter mentions in a video of his that he had purposely broken lens made for him to achieve his center selective focus, specifically the images with the vignetting at the edges. My question is still what exactly did he do to the lens elements in order to achieve this. You can even see the lens on his video, it does not look like it belongs on a hasselblad, but instead a 35mm or another type of medium format camera.</p> Link to comment Share on other sites More sharing options...
