Canon General / Lens Rentals Canon 100-400 IS Mk II tear down.
« on: February 14, 2015, 08:24:28 PM »
Hi Folks.
Just thought I'd let you all know (well those of you that didn't already know) that there is a great article from Roger at lens rentals, Canon 100-400 IS Mk II lens in bits all over his bench here..
As ever a very well written piece. I'm not sure but I think he likes the build quality of this lens! ::) :o ;D

Cheers, Graham.

Landscape / Rusting Relic
« on: February 11, 2015, 07:23:31 PM »
Hi Folks.
This is a Paddle Steamer, the Ryde, built in 1937 she used to ply the Solent from Ryde to Portsmouth she also saw service as HMS Ryde. She also served as a disco in her little lagoon during my youth! Sadly she is a decaying hulk now with more holes than metal, she is scheduled for removal soon (some point during the improvement of the harbour behind her starboard side and to the front of her bow) in the next couple of years. Thought I would share the pictures here.
Still struggling with the processing, have I overdone it, your thoughts please.
Excerpt from Wikipedia. Full story here. http://en.wikipedia.org/wiki/PS_Ryde

HMS Ryde 1939 – 1945
In 1939 PS Ryde and PS Sandown were requisitioned by the Royal Navy. She was renamed as HMS Ryde and initially both were used as Minesweepers in the Dover Straits. After two years Ryde was converted to an anti-aircraft ship and served on the Thames Estuary and at Harwich. In May 1944 she travelled to Portsmouth from where she embarked to the Normandy coast to take part in the naval component of Operation Neptune on D-Day.

Sports / Big Boat Fell Over!
« on: January 30, 2015, 08:23:46 PM »
Hi Folks.
Didn't really know where to post this, not really sports, but most transport stuff seems to be here.
A few weeks ago the Hoegh Osaka was deliberately grounded after taking on a severe list to prevent it sinking, I managed to get to the seafront whilst things were still happening. A few of the long exposures I took follow, plus some others.
She is a vehicle carrier loaded with luxury cars and some heavy plant machinery, apparently once she started to list a large excavator moved and punched a hole. No deaths, some minor injuries and bruising including a couple of hurt prides from what I understand.

This one shows the Air Sea Rescue chopper arriving.

Why the focus is soft on the previous shot, this is approximately what I could see to focus on.

Taken from the ferry, crossing from East Cowes to Southampton. This is after she floated off and was relocated before commencing pumping out.

Edit, please feel free to advise me on my post processing as I'm real new to PP, also feel free to post similar events, sea or land, could change the title to suit.
Thanks for looking.

Technical Support / Dust on sensor.
« on: January 27, 2015, 02:55:35 PM »
Hi Folks.
Could someone confirm my understanding or point me in the right direction please.
I have a large L shaped hair or other impediment on the top left of my images, am I correct that would make its actual location bottom right on the sensor face. I have thought until I made myself stupid on this one.  ;D
I have done a wet clean with a visible dust kit, and don't seem to be able to shift whatever it is, so I am looking with a light and magnifying glass but can't see it. Starting to think it may be a scratch, I bought the body used so have no idea of the history.

Cheers, Graham.

Canon General / What do you copy from your camera card?
« on: December 29, 2014, 11:27:56 AM »
Hi Folks.
When you copy your images from your camera card, what do you do with the CTG file iN the MISC folder, copy it, discard it, ignore it?
Does it have a use outside of the camera?
Thanks in advance.

Cheers, Graham.

Software & Accessories / Dead pixel count DxO?
« on: December 25, 2014, 09:56:23 PM »
Hi Folks.
I have been wondering about the 24 dead pixel count in my DxO 9.5 install. A couple of days ago I was going through DxO with a couple of friends, think blind leading the blind, anyway one is using the free version of DxO 8, the other just upgraded his free licence to version 10, their cameras are a 50D and 400D respectively, and their software also says 24 dead pixels. Is this just some arbitrary number set by a programmer, or an accurate read of the sensor, if so what are the odds of all of us having 24 dead pixels?  :o :-\
Does anyone know a trusted technique to be able to count dead pixels please.

Cheers, Graham.

Technical Support / Question about 50D known issues or recalls.
« on: December 17, 2014, 08:25:29 PM »
Hi Folks.
A friend of mind has just picked up a 50D, it has a short warranty and about 8500 shutter actuations, any known issues with this body, recalls etc. He would like to know what to look for before the warranty runs out.
On the subject of recalls, do Canon cover older models, out of production and warranty, will they cover a recall on second hand gear or only for the original owner? 

Cheers, Graham..

Canon General / Resurrection, of the posting kind.
« on: December 13, 2014, 06:15:58 AM »
Hi Folks.
Is it me or are we getting a whole lot of 1 or 2yr old posts about scams etc resurrected by 1st time posters recently?
I have been going to reply to a couple of them then checked the previous post because I thought I recognised the thread from my early days.
A lot of long serving members are then sucked in, adding to the momentum, can we get these older scam posts locked so they are there for reference only or would that be too difficult?
Just a thought, perhaps it is only me that it bothers?
Please understand I don't see resurrecting an interesting post as a sin, just the scam ones! ;D

Cheers, Graham.

Canon General / RTFM. Do you?
« on: December 10, 2014, 10:00:21 AM »
Hi Folks.
Just for giggles and to save hijacking someone else's post, do you RTFM, and what drove you to it?
I first resorted to RTFM as a child many years ago when I was trying to build a Technical Lego tractor from the picture on the front of the box! It hadn't gone too well, not as simple as it was to build the standard Lego cars and such just from the box image!
Technical Lego was new then, before it was called Lego Technics!
Since then I have tended to Read The Flamin' Manual first for most stuff.

Cheers, Graham.

Canon General / Please help me! 1DX Fever, (G.A.S.)
« on: November 30, 2014, 02:03:10 PM »
Hi Folks.

Please help me, I went to the LCE Southampton show and I did not follow the advice previously given on this forum, I picked up the 1DX, held it, tried it, and I now find I am in desperate need of the antidote for trying a 1DX! I fear that not being able to afford one is only part of the antidote!  :'( Damn that thing feels good with a big white on it.
Should have stopped after trying the 5DIII! ;D

Cheers, Graham.

Technical Support / Need help with 450D losing time and date please.
« on: November 22, 2014, 08:52:05 PM »
Hi Folks.
A friend has just bought a 450D kit, may not have been the bargain he thought!
Each time he removes the battery, the time and date are reset, I know this means that the backup battery is flat, the problem is that on the 450D the battery is a "built in secondary battery" p183 of the manual.
So far I have read that sitting discharged for a long time kills these rechargeable cells, seems most cameras out there come with the rider, "not been used for ages so thought I'd sell it"!
Will it only charge from a "full" battery? He has 3 batteries, one won't fit because it is swollen, one we freshly charged and on insertion only showed 1/3, or is it 1/4, the other only seems to charge to 1/2. He is reluctant to spend money on new batteries if this body is a dud. Anyone know if it is within the scope of DIY replacement to swap out these built in backup cells? If he has to try again he will probably go after a XXD. (My fault, I showed him how much easier setting changes are on a 40D!)
Hoping that between you folks you can enlighten us on these questions.

Thanks in advance.
Cheers, Graham.

Edit. Just a thought, I guess this would mean custom menu settings would be lost too? Or are they written to non volatile memory?

Canon General / Lucerne, where to go?
« on: October 30, 2014, 04:15:00 PM »
Hi Folks.
Going to be in Lucerne for a couple of days this weekend, anything recommended to see in the immediate locality? Needs to be within public transport range, not necessarily photo related. Short notice as it was a bit unexpected!

Any ideas appreciated.

Cheers, Graham.

Canon General / Lens identity?
« on: October 27, 2014, 08:47:00 PM »
Hi Folks.
I hope someone can identify this lens for me please, it is a ropey picture from a for sale add. Long story short, I don't want to seem too interested in it, asking too many questions might increase the price as it is on a camera with problems for sale make a sensible offer. Knowing what it is will help me decide on an offer price, or if I even want it.

Thanks for taking time.

Cheers, Graham.

Technical Support / Downside Up?
« on: September 27, 2014, 08:27:21 PM »
Hi Folks.
I was out today doing some landscape shots with the camera upside down, came home and put them on the computer, clunky old laptop, where they were displayed inverted.
My question is why were they not displayed up the right way, I have rotation set to computer only on my 7D, shot raw only. Does this setting only affect JPEGs, does it only work for 90 degree rotation, i.e. portrait and cannot recognise an inverted camera?
I checked the software, Fast Stone Image Viewer, which was set to rotate according to exif data.
Is there a way to rotate the raw file, or is this not a good idea due to having to overwrite the original? Is there a way to get it to display upside up!

Thanks for your help.

Cheers, Graham.

Canon General / How do you cull your photo's?
« on: September 07, 2014, 05:05:58 PM »
Hi Folks.
I went to the Bournemouth Air Festival last weekend, so many excellent planes, though the sad thing was that the Canadian Lancaster was not able to fly due to an engine failure, really wanted to see two Lancs together.  :'(
The problem is I now have 3 thousand pictures over the two days, I was wondering if any of you have any tips on how to cull the shots?
Saturday was rather dull and overcast, I was going to ditch most of the pictures taken Saturday but I already found a couple that look like I was flying above the display plane looking down on it flying above the clouds!
I'm already going through and ditching any that are OOF or have bits cropped off accidentally, but how do you distinguish between 2 similar shots, so far I have used whether the prop blades are obscured or other similar things, any tips? Flicking back and forth between the raws in windows viewer is taking ages, and this is the first time I shot raw only!
I don't want to try to open thousands of images in DxO, I think it will crash may PC! :o ;D

Also how do you get the props or rotor blades to blur without blurring the whole thing, I dropped the shutter speed progressively until I had blade blur but got about 5 keepers from dozens of shots, speed was well below 1/focal length less four stops for the IS, I guess it is down to panning technique more than anything else?

Cheers, Graham.
