2. 5 Discussion amp Implications for Design Having described our findings about the needs the behaviour and the problems of amateur photographers it is now time to discuss these findings with a view to wards their implications for the design of digital photography products and services We begin by drafting a persona that consolidates our findings and justifies the sub sequent design proposals This is followed by a critique on the design of current digital cameras and a discussion of a novel imaging paradigm We then discuss the issues surrounding editing tools and propose editing paradigms aligned to the needs of amateur photographers Finally the problems that amateur photographers encounter while learning about digital photography are examined and a novel form of learning tools is suggested 5 1 A persona of an amateur photographer As a first step towards consolidating our findings in a form useful for design we have created a persona of an amateur photographer see Figure 5 1 A persona Cooper 1999 is a precise description of our user and what he wishes to accom plish Our persona incorporates the findings about the context in which personal photograph is used the attention that amateur photographers pay to picture qual ity and the problems they face with current digital cameras This persona has been used in drafting our recommendations for design that are presented along with the discussion of our findings in the foll

4. Having a better understanding of the needs of amateur photographers and the prob lems that they face a series of recommendations were made about the design of digital photography products We explained why digital cameras should move from feature bloat to a new imaging paradigm that requires less intervention by time strapped amateur photographers Further proposals were made about the design of editing software that is more closely integrated with an amateur photographer s workflow and can be used without advanced knowledge of editing methods Finally 50 Conclusion Future work we presented an idea for a novel learning tool that could help amateur photogra phers make the most out of their cameras without having to go through complex and often poorly written instruction manuals 6 1 Future work As this study was an exploratory one it has covered a breadth of topics but has left several questions open to a more in depth investigation First of all by recruiting a random sample of participants we were able to experience a wide variety of phe nomena but not all phenomena were reported by all participants For example not all participants would regularly edit their photographs Thus the information that we collected for each phenomenon is inherently limited as it comes from only part of our sample However now that a set of phenomena relevant to the amateur use of digital photograph has been identified each of them can be studied

11. This was because images on a compute screen lack the tangibility and manipulability of prints meaning that it s almost impossible to spontaneously move them around and compare them to each other A later ethnographic study that took place in 2001 across 22 households in the UK was published by Crabtree et al 2004 They focused on analysing photo talk which they define as the conversations that take place during co present photo shar ing Their conclusion is that the most important feature of sharing photographs is the production of an account that gives the photos in hand their particular mean ing If this feature is not adequately supported in digital photo sharing technolo gies especially in those technologies that underpin remote sharing we risk losing the very practices that allow photographs to be shared in a meaningful way Finally Lindley and Monk 2006 examine co present photo sharing from the view point of defining a set of affordances They argue that technologies for sharing digital photographs should afford enjoyment conversation and control For example one way a digital slide show could afford conversation and control is by allowing the viewers to control the rate of presentation and to pause on a selected image so as not to interrupt ongoing conversations Although all these studies do shed some light on the nature of photo sharing con versations there are still certain aspects that need further inv

When we got back from Chile we bored all of our family with going through a slideshow of all of the pictures and stuff on various computers we just took our camera around and plugged it in to people s computers 00 14 14 27 No I don t think we uploaded it anywhere actually we ve only shown it either through the PC or sometimes you can plug the camera in the TV but only when you remember the right lead which is very rarely 00 14 38 19 I think a lot of people thought that it looks a bit unreal the 64 sky almost looks like a painting rather than a real sky so a lot of people asked if that s what it actually looked like so that s interesting I guess I think part of this didn t quite look like this part of it is an effect I think of the camera it s made it look a bit unreal but it actually evokes what it felt like very well So yes I think people liked that one I don t think it s an amazing photo I don t think I ve taken an amazing photo I just think it s very pretty 00 15 39 07 I like it because it reminds me of being down there and as I said it really captures they way I felt when I was taking the photo just bc it looks a little bit surreal but it also looks very majestic 00 16 54 08 PHOTO 2 We ve got a lot of nice pictures of upwards looking buildings which is a bit of a favorite type of photographs That s one This one actually is from Peru from the same trip This is where

15. independently in more depth For example a follow up study could focus on the photo editing be haviour of amateur photographers For such a study our findings on photo editing can be used as an initial approximation that would shape more specific research questions Obviously participants in such a study will have to be selected among those amateur photographers that do edit their photographs regularly One finding that warrants further investigation is the amateur photographers per ception of image quality In the present study the quality criteria have been sub jectively defined based on some of the phrases used by participants It remains an open question whether these criteria could be defined in a more objective and measurable way and what would these definitions be For example participants talked about over and under exposed photographs but we could not precisely de fine what makes an amateur photographer consider that photograph is properly exposed Such a question could perhaps be answered through a carefully controlled experiment taking account of existing work on visual perception Further research is also needed for evaluating the design recommendations made as part of this study Especially when features are meant to function automatically their function should be properly specified so that they err on the side of caution and do not become a nuisance to the user In order to ensure user acceptance each of the proposed sol

I came in here and printed out some photos 4 1 2 The social context Most of the participants who attended a social event during the intermediate period of the study had some comments about the experience of taking photographs during such an event One participant explained why he took only a few photographs during a family weekend T don t like to be behind the camera all the time If I go away for the weekend on a holiday or walking or something like that I d probably take more photos When I m with friends and family I take some photos especially if it s people I haven t seen for a little while but I don t like to take lots of photos because then you don t get to talk to people For this participant socialising was more important than taking photographs which was done more actively in activities less associated with a social context Another participant commented on the pressure she felt while taking photographs at a social event attended by many people I always find it really annoying to take pictures when there s a lot of people because you re just so aware of it for example the person that s posing feels awkward posing because there are so many other people around Finally two contrasting opinions by two individuals attending the same social event a wedding show how personal social attitudes may alter one s photo shooting strategies in this case in terms of positioning oneself at a

ISO the white balance and obviously the shutter speed and aperture bracketing it s all now done on buttons on the outside so you don t have to go into the menus Even when amateur photographers find a way to make adjustments these adjust ments can be the cause of further problems As each of the adjustments places the camera in a new mode of operation and there are hundreds of combinations for such modes it is not surprising that participants reported several instances of mode errors where the camera was left in a mode that was inappropriate for capturing a later scene In one case the camera had possibly been set to the wrong mode by another person which was not noticed by the participant I realised later that my camera was still in macro mode because I had taken some macro shots earlier so I think that might have had an effect on how this photograph looks as well I was actually using flash by accident for a lot of these pictures It was pointed out to me by a friend who said It s probably one of the sunniest days of the year do you really need your flash on and I said no probably not at which point it was turned off I think it probably does show the status of the flash on the camera screen but I paid no attention There was something wrong with my camera that day I don t know what it was My little brother was playing around with my camera so I think he just messed around with t

The first theme is related to the context of personal photography which includes information on the way photography fits in the participants lives The second theme encompasses the subjective evaluations that participants made about their photographs A taxonomy was created for classifying the criteria that partic ipants used in these evaluations The third theme is centred around the problems that participants reported they face while using digital photography products and services 4 1 The context of personal photography In most occasions during which participants shot photographs photography was not the primary activity taking place Only one participant reported going somewhere for the purpose of taking photographs although this was still combined with going out for a recreational walk The vast majority of photographs were shot during different social and recreational occasions The photo shooting occasions that we observed belonged to one of the following categories Travelling on vacation Going on a weekend trip Going out for a walk Visiting a museum Spending the night out with friends Attending a music festival Attending a wedding Two implications of photography being a secondary activity were found first of all people do not devote enough time to improving their photographs and their photographic skills Second the number of photographs taken and the time devoted to taking them is often reduced because of

111. we started taking this pictures of buildings at the base of them looking up into the sky 00 17 54 20 With these ones we ve actually printed them out and put them in an album which is pretty rare actually bc we don t print things out very often But I think that we took them to one of these photo shops where you can actually turn your digital photos into real photos and we ve shared them that way too 00 18 20 29 We selected I think the best 100 or so You just go through them and say I like that one and that one there are some that just aren t very good bc u can t really see people s faces or sth like that so u can get rid of those pretty easily And then there are some which are two versions of the same photo and you pick the best one the one that s got the best colour that captures it best And then u have to take them and get them printed out I m not sure why we got them printed out just for nostalgia s sake or sth like that 00 19 33 09 One of the things that we use quite a lot is to rotate then because irritatingly the DC doesn t do that It can t tell that you ve got it that way up or the other way A lot of our photos have been rotated I don t think either of the last two have been edited any further 00 20 05 16 PHOTO 3 That s the Nazca lines and we had to do a lot of editing the original photo is here somewhere So that was the original photo and it s out of the window of
