Tutor's report : Feedback on Assignment 2


Overall Comments
Things are moving in the right direction.  I note that you are trying to find themes to link your image making for the assignments and I whole heartedly approve of this approach.  I would suggest that you think about the different ways you can do this, the possibilities of more conceptual themes some of which I indicate in the annotations but to reiterate, colour, mood, emotion, can be as much and sometimes more of a theme than location or absolute content.
A creative interpretation of the briefs, so long as the main aims are covered, is very much favoured by all us tutors and the assessors where possible and can sometimes help you to develop you own vision much more than taking a more literal approach to the briefs.
 
Feedback on assignment
In very many ways this has been a successful assignment.  The images you have come up with, particularly in part one, are all of a good standard in just about every way and although you have not produced a set of images on a single theme, as you intended at first, there are some themes emerging here and you might like to sort them in different ways to see what themes you can find.
I think that you have covered much of the intentions of the brief and the following remarks are intended to help you in the future rather than suggesting ways in which you might re-work the current set...though if you feel it useful to re-work any of them in light of these comments, re-shooting or whatever, do so and include the results and your thoughts on them with the assignment when going for assessment.  Re visiting and re-working assignments in light of tutorial input and future knowledge is always credited by the assessors and, rather more importantly, a valuable learning technique.  Of course you should always indicate what is re-worked and reflect on the results.

P540 – you comment that you are not really satisfied with the way your image captures the intrigue of the Lanes.  I thought about the idea of a narrow and tall lane and cropped accordingly...what do you think?  Actually your image doesn’t miss by much if at all.
Like the amended version....the narrower  version does capture the feel of the Lanes  better.

I see a post on your blog concerned with shooting RAW vs jpeg.  I am not sure what conclusions you came to but equally I am not sure that you understand the difference so I hope this is not simply telling you things that you already know!

Raw images are simply the unprocessed information captured by the sensor, some information such as selected white balance is passed on but the image is ‘as is’.  All cameras, whatever the output, in fact capture a raw image but if jpeg of tiff or whatever (not the proprietary raw output though) output is chosen the camera applies post processing of a variety of sorts depending on the settings chosen by the photographer before compressing the image.  The original, unprocessed image cannot be obtained from the jpeg as the information and pixels are deleted.  Therefore it is generally considered more sensible for the photographer to shoot and output raw images and apply their own post processing rather than rely on some generic answers dreamed up by the camera designers.  This allows for a variety of different post processing solutions to be tried and at different times, leaving the options open.  Obviously this assumes that the photographer downloads and stores the raw images for posterity rather than deleting them after initial post processing, rather in the same way that film photographers will store the negatives for future reconsideration.  It is inevitable that the raw image looks different from and often much worse than, a jpeg of the exact same subject if looked at before processing in a program like Lightroom, Camera Raw or the raw conversion software that the camera manufacturer issues with the camera.

You should answer the questions I ask in my annotation, or in the tutor report in your learning blog.  They are put there to make you think about it and not so much for you to send me answers.  If I want a direct answer I will say something like “Let me know what you intend etc....”  I want to encourage you, and all students, to use their logs and blogs as a vehicle for this sort of thinking, musing and exploration.

I am not convinced that the module notes have entirely explained to you the way that a light meter works so I will try to give a brief outline of what I think are the important considerations.  The problem that a meter is trying to solve is, of course, what exposure we should give the sensor, film or whatever.  Given that all subjects are different some sort of baseline needs to be establishes and in the days of monochrome photography the solution was based on tonality and this seems to work just as well in colour and digital as well as analogue.  So what to do? Measuring the absolute amount of light reflected from a particular subject is fine but complex and difficult to interpret so it was decided to pick a reference colour and tone and this was (to be a bit over technical) 18% reflectance neutral grey, usually referred to as ‘mid-grey’ because although it only reflects 18% of the light falling on it it looks about halfway between black and white to our eye (Logarithms and things enter here!)  So all light meters assume that they are looking at mid-grey and suggest an exposure that will render the subject as such.  This means that if you take a spot reading off a white surface the exposure will be too little to render it as white in other words it will under expose it.  As it happens (well, this was a part of the decision to use mid-grey and the particular sensitivity range of light sensitive materials in reality), an average, naturally lit scene (the sort of thing that is most often photographed in fact) averages to mid-grey (a tonal range of about 127:1 and so on) so pointing a light meter in the general direction of the scene and taking in as much as possible (and average reading) we tend to get an acceptable result.  However, we want to be able to do more than get just an acceptable result and so all sorts of systems of exposure estimation have been devised over the years and the one that has been most often adopted and abused to be honest, is the Zone System of Ansel Adams.  This can be extremely comprehensive and complex and the three volume series of book he wrote on the subject of exposure (The Camera, The Negative and The Print) have become something of a holy text for some photographers and go well beyond the current discussion.  However there are a few gems to be extracted that can help in explaining how to judge exposure in every day situations.  His splitting of the scene into up to ten tone ‘zones’ from pure white with no detail (pretty much the point of highlight clipping in our day) to pure black with no detail (the point of shadow clipping) is not a bad way of thinking about a subject.  So if you look back on the way you took your readings in the light of this information you might be able to be more specific in understanding how you got the results that you did.  And what you might have done to either make your life easier or simply been more predictive of the results.  It might help to make sense of some of my comments and questions.  I have included a link to one of the many sites that discusses the Zone System in a supposedly simply way, take a look and see what you make of it. 

Explain in you blog why you chose the particular points you did to measure and In the light of the above, whether they were the best to achieve the results you were after.

You have used the lighting to draw the eye to the elements in the image that you want the viewer to concentrate on, the main point of interest, what Barthes (see suggested reading) might have termed the punctum in many ways. This has been successful and is a very worthwhile technique to use but you should also consider using it in conjunction with, or on occasions to substitute it with differential focus.  By this I mean focusing specifically on your main point of interest often throwing the other elements more or less out of focus.  With modern small sensor cameras the depth of field is generally quite large so that the point of absolute sharp focus may well not be that different from the rest of the image but it can be enough to work almost subliminally and pull the eye in.  The depth of field is dependent on focal length (the longer it is the shallower is the depth of field); the aperture (the wider the aperture the shallower the depth of field) and the point of focus (the nearer it is the shallower the depth of field) so even with a crop factor of 1.5 or whatever we still have some control over it.  Look at your images and discuss in your blog if and how you could have used differential focus and/or depth of field control to make your images even better.

I am pleased to see that you seem to be using the histogram and so on to evaluate the success or otherwise of the exposure but it can be all too easy to simply concentrate on the info regarding clipping and ignore the rest of the placement of tones.  Quite often we are better to let one or even both ends of the tonal range to block up in order to arrange the important tones where we want them and it is important to get used to looking at different colours in terms of tones, the spot meter setting can help here.  A yellow can look lighter than a blue of the same tone!

 
Learning Logs/Critical essays

Your blog is coming along reasonably well. I an glad to see that you are recording your visits and so on not just the exercises.  However I would like to see you using the blog more like a free ranging journal, recording you thoughts, reflections, questions and so on about all sorts of issues that inping on your study and photography. 

Perhaps if you think of it as having a sort of conversation with yourself about your engagement with photography and the arts and life in general (it doesn’t have to be Proust length!) you won’t go far wrong.

Happy to give this a go now that I have a feel for what is needed here..

Suggested reading/viewing

Have decided to set up a different part of the log to keep all suggestions received together with any comments that I want to make about what I've read etc..

Barthes introduces us to some interesting ideas about the way our attention is affected by photographs (amongst much else) in:
Barthes, R., 1993. Camera Lucida: Refections on Photography. London: Vintage Classics.
Take a look at this site


for more information on applying the Zone System to digital photography, it might be more information than you think you need but information is never wasted.
