These are a couple of photos of me working on the clay pattern for one of my bas-reliefs of John Monash for my next exhibition “In Search of Sir John Monash” to be held at The Highway Gallery, Mt. Waverley, 2nd to 15th November 2013.

Google are about to updated their terms of service (TOS) and it is very refreshing to see an on-line service provider, firstly notify its users about the changes and also focus on those aspects that let the user control what is to be shared. However the common click to accept terms, expressed in very verbose legalese, are seldom read by most of us. we just want to join up not spend half and hour or more trying to figure out what is meant.
If you are creative type and produce original works it is really in your interest to review the TOS of all on-line services you use. Many services assume ownership of anything your uploaded into their services, Facebook and Instagram assume you given then very draconian rights over redistribution, Dropbox which one held part of the middle grade have recently changed to claim more rights over your content. Flick/Yahoo! and google+ are generally considered better. Terms of Service are fine, and necessary, they cover such things as the services right to cancel your account if you do bad things and the fact that they may take little or no responsibility for what you upload, most don’t claim they own your content but that statement will probably be followed by a clause that you “grant them non-exclusive, fully paid and royalty-free, transferable, sub-licensable, worldwide license to use the Content that you post”. If you are not ok with this perhaps it is best not to use that service!
If like most of us you have tried to read the fine print and are still uncertain, here is a community (ToS;DR Terms of Service Didn’t Read) and website that understand and they aim to address and fix the biggest lie on the web “I have read and agree to the Terms” in one click!

Looking back through my blog post I have come across a number of weird links, Not all are like this but this one is really weird. I can only assume either google has been doing some “recoding” of links to other items in blogger and picasa web albums or some entity (a hacker or scammer) has managed to access my google account. Just in case of the later I’ve changed my password yet again! It is possible theses are related to changes in google+ photo. They seem easy enough to fix once you know which are the broken links, you can just edit them with the correct link location, which in the case of photos is a bit or work BUT I don;t feel link searching through every link in my 1480 posts and manually fixing the ones that are broken!
This not one of the typical messages given in google’s help for hacked sites. Has anyone else seen massages like this?
In light of the adobe hack it is probably that now id the right time to change your passwords on every social site (and close the accounts on those ones you not regularly using)..

I am starting to worry I’m just becoming a bit of a grumpy, and I’m not going to waste more time investigating in the hope it will all be fixed, Now as I am writing this I got a notice that google+ has Auto Awesomed me! Not the original photos in google drive but via the jpegs in my blog post? Its all a bit to incestuous, They are meant as comparative photos not a animated movie btw.
Really google does your right hand know what the left is doing?
Please leave Picasa and Picasa Web uncompromised.
arning, I must preface this post with the advice that this is very much my personal view, based on my experience rather that on a calibrated benchmark comparison. I have the choice of using jpeg, two types of propriety RAW and .DNG as an alternative Raw format on my Pentax K20D. I have found the decision as to which format to standardize on hard to resolve and opted to save both RAW+jpeg where there is the such an option. So here is a little about my (in)decisions and why.
All my current and past digital cameras and cameraphones have all captured .jpeg files and my photo collection is dominated by that format. I have come to appreciate picasa as the very best way to manage jpeg files, its fast, simple and behaves. My many mistress project has lead me to see that previewing jpeg thumbnails is by far my preferred way to cull and organise my photos as I load them. At this stage whilst I might do a little cropping I tend not to do any elaborate post processing. Occasionally at this stage I will email images and very occasionally upload them to the net which generally require resized jpeg version (again picasa does this well) without much photo retouching.
There is also no doubt in my mind that you can coax much more out of RAW files than you can get out of the equivalent jpeg. The reasons for this is buried in the image "development" process happening in the camera, to take the sensor readings and produce an image. There are several steps, demosaicing of the Bayer array, white balance assumption, tone mapping, colour saturation and contrast, then image compression before it is written to the camera memory card.. Probably the biggest limitation is that the image must be packed into an 8 bit representation. Each step requires interpretive decision about how to preform the development and many are not easily recovered if the steps lead to less than desirable processing. That’s where having access to the original information in a RAW format file is a big advantage, but now the steps must be specifically undertaken by the photographer, which takes time and experience. Often a lot of time! The jpeg representation, or at least a suitable small sized thumbnail of it, is also needed at the camera itself to be display on the LCD screen on the back of the camera.
|Pentax JPEG *** (5.9MB)||Pentax JPEG **** (10.0MB)|
There is a trade off between the time take to write the large RAW files and the smaller jpeg files, which can mean that you can take fewer images per second, because there can be a bottleneck writing to the card, When you just shoot raw, the jpeg development steps are likely to be run anyway, not only for the image on the LCD screen but most Raw files also include this jpeg thumbnail, for use in quickly previewing the Raw file contents. So in RAW+jpeg both file formats must be written to you to your memory card and it is then just an issue of time taken to write both and extra space required. So fewer unique images fit on the memory card before it is full. Rather than opt for a larger memory card. I've chosen to have several 4 & 8GB cards that have faster read write access, so other than having to change cards more often I probably don't see much difference. There is one exception which is tracking birds in flight and I'll discuss this in a future post.
|Pentax RAW .PEF (13.2MB)||Pentax RAW .DNG (23.1MB)|
|Cannon JPEG (4.5MB)||Canon RAW .CR2 (16.8MB)|
So I hope you understand why I choose to store RAW+jpeg and have opted to stick with the PEF format (and .CR2) rather than use DNG from the camera. I do use the DNG format in some special circumstances but that’s for another post.This discussion is prompted by to my thinking longer term focus
Thanks again to Jessica Hische for her great drop caps.

The message looked authentic but seemed suspect to me, why was the only option to change my password and why was this necessary but on checking the links names I followed the instructions, and waited ...and waited …and waited for the promised email. After 20 minutes I gave up and did other things. About half an hour later the email had arrived and I followed a new clink on link which only gave me the option of typing in a new password and a duplicate. Now this made me really suspicious! Being sent a false login page to capture your password is a very common phishing scam. However on investigation I again felt that the link address I could see and the mysterious email address cs-auto from adobe were possible legit. So I did some what cautiously change my password. Ok no drama after that, other than I missed my self imposed deadline. I also suggest if you in the same position, consider changing your password a second time, like I did, but this time accessing adobe.com and my adobe directly, not by a link from an email!
Now I see what was going on, Adobe has had a massive hacker attack, and only today can I find information from them about their "Customer Security Alert". If Adobe knew about this on the 17th September why didn't they notify their subscribers back then?
More importantly why did adobe choose to run something to force everyone involved to change their passwords,
- Without telling them why ?
- Doing it such a scammish fashion?
