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.

Canon General / Those D'oh moments!
« on: September 07, 2014, 04:16:49 PM »
Hi Folks.
Well I went to the Bournemouth Air Festival last weekend, what a great event! Thanks to those who guided me on camera body lens combinations to take.
Saturday I got the kit sorted and started walking away from the car, she says have you got spare batteries and cards, D'oh pick up spare cards, I was relying on gripped bodies to only need the batteries on board for the days shooting! They made it with loads in reserve.
Sunday I'm in a nice little spot part way up the cliff shooting merrily away and get the CF FULL message, reach to my pocket, D'oh no spares much muttering and cursing and another photographer with Nikon gear noticed my distress and offered to lend me a card, thanks Kim, but I decided that the best way was to punish myself with a forced march back to the car for my own cards.
I discovered after the first ten to fifteen minutes of both days that I had left the ISO cranked up from the night before, D'oh, not critical but it does hurt image quality a bit when you don't need the high ISO.
Seems about the only thing I got right was the carrying system, a Black Rapid Double fixed to the tripod feet, and OpTech 3/8 webbing on the body lugs with an OpTech utility loop on the belt loop of my trousers for security during the walk in and back.
On the forced march back to the car I had that heart in the mouth moment when the shoulder strap went light by about the weight of the body, and I heard things rattle on the ground! Phew the body was swinging on the strap in front of my leg, I know exactly what happened, the phone in my pocket knocked the lens release and the walking action twisted the body off the lens. The rattle on the ground was the hot shoe cover had fallen out!
I had read the posts about bodies dropping off lenses sometimes with catastrophic results and thought that it may have been a freak occurrence, I can tell you it happens easier than you might think, it fell off on the way back to the show too.

Let's just say I know why I will never be a professional!  ;D

Cheers, Graham.

Software & Accessories / Jpeg image sizes?
« on: August 25, 2014, 02:08:44 PM »
Hi Folks.
I was just spending some time getting to grips with DxO. I exported some images to file as Jpegs, they were in the order of 20Mb. I thought I could get away with half size for what I wanted as I have no intention of discarding the raw file!
I see a scale in DxO export settings, Quality 0-100, must be percent right? That is the first assumption that will prove a point! ;D
It obviously isn't percentage, but what is it, from trial and error I find that somewhere in the 96-97 range gives half size files! Please see attached list.


Dxo jpeg sizes by Valvebounce25, on Flickr

The blue highlighted set is from one image, I realised it was a crop when I went to compare the raw file so I repeated the 95-100 set and added the raw for comparison. Can anyone tell me how this scale works, it just seems completely random that a quality of 50/100ths (%? ;D) can give a file size of 1/16th the full size file.
Someone must know the answer to this, please! It's making my brain ache!  (How do you draw a smiley with smoke coming out the ears?) ;D
Thanks in advance for help with this, I know it is not necessary to know the answer but enquiring minds need (like) to know.

Cheers, Graham.

EOS Bodies - For Stills / Lens to body pairing
« on: August 19, 2014, 09:53:17 AM »
Hi Folks.
I am going to the Bournemouth air festival, for those that don't know it is a free display with the aircraft flying over the coast, no access to parked aircraft as far as I am aware.
I would like to know the thoughts of those wiser than myself on which lens to put with which body for best image quality?
My thoughts are:-

Bodies                    lenses
7D        With      EF 70-200 f2.8 IS II with or without EF 2X III depending on how close or far the planes are. 
40D      With      Sigma 150-500 f5-6.3 DG OS HSM

Please could I have your thoughts on whether this is right or wrong!
Is it worth having the extra camera just for the extra 100mm?
I am looking to get a Black Rapid Double for carrying both, as it converts neatly to a single too when I only want to carry one body. Thoughts on that?
Anyone been and able to tell me if I will need the 2X III on the 70-200 or not?
Thanks in advance for your input.

Cheers Graham.

Software & Accessories / Benbo Tripod?
« on: July 29, 2014, 08:30:07 PM »
Hi Folks.
Anyone used a Benbo Tripod, there is one for sale locally that might be toooo cheap to pass up if they are any good! In fact there are two now at pretty good prices if they are good!
Thanks for any feedback, btw that is Benbo (apparently stands for bent bolt) not Benro which I saw was not too good from recent posts.

Cheers Graham.

Software & Accessories / DxO upgrade question.
« on: July 24, 2014, 04:31:29 PM »
Hi Folks.
I have decided to get DxO, I have found version 9.0 genuine licensed boxed product on disc cheaper than the version 9.5 download before the special offer finished.
I would like to know if upgrading from 9.0 to 9.5 is one of the free minor upgrades, if I have to pay it is possibly not worth doing.
Anyone using DxO know the answer please?

Cheers Graham.

Canon General / Exif data, does it help, do you need it shown?
« on: July 23, 2014, 07:59:43 PM »
Hi Folks.
I often view images on the forum, almost exclusively on a tablet, some images are hosted on Flickr or similar, so I can see the exif if I click through, others don't have this facility, and I can't view the exif with a right click like I could on a PC.
I know I'm not the only one who asks for camera settings and gear configuration for the shots to be added, I'm just trying to find out why.
Multiple votes are allowed, there are 6 votes allowed for ten questions. For instance I sometimes use my Android tablet but mostly iPad so both are relevant.
Please feel free to add any thoughts in a reply.

Cheers Graham

Software & Accessories / DxO Question?
« on: July 19, 2014, 11:30:32 AM »
Hi Folks.
A question about working with DxO? I was wondering if it is possible to create the recipe on a laptop and then process the adjustments using a powerful PC? If I understand correctly the adjustments are stored in a (sidecar?) file needing only limited processor power then on export to file etc the processor power is required.

Cheers Graham.

Software & Accessories / A little help with DxO please.
« on: July 12, 2014, 09:53:57 AM »
Hi Folks.
I have been experimenting with DxO and so far I really like it, really impressed with the auto capabilities but I could use a bit of help please.
I unchecked the download new profiles automatically and cannot find where to enable it again. Also I see a part of the installation called database, is this just for profiles, or is this where it stores all of my adjustments? I ask because I have a small Windows drive which I try to keep clean so that a windows reinstall does not have any impact on files I create, therefore I don't have space for a large database and would want photo adjustments on the drive with the photos.
Thank you for any help.

Cheers Graham.

Software & Accessories / Post Processing help please.
« on: July 04, 2014, 08:39:07 PM »
Hi Folks.
Some of you with whom I have conversed will know I have thousands of raw images, 7D 40D and a few from 20D and 300D and still only use JPEGs straight out of camera.
I plan to change that, and on that note I set out with DPP and processed a couple of pictures, then converted to JPEG, first question what is the best way to reduce the size of the JPEG? Ideally I'd like to have them about the same size as the out of camera JPEGs, 6 Mb (ish) preferably without reducing the pixel count. I was stunned at finding 20 Mb JPEGs!
I went to post the before and after JPEGs for advice on how badly I'd done when I discovered the size because it wouldn't let me upload to Flickr!
I found save as recipe, is that recipe able to be used to batch process. Is there a setup of the sharpness unsharp mask that will work reliably on most pictures to improve them, leaving me to attend to the few that won't go with a batch process?
As I have my own import and storage regimen I don't need or want software that wants to change my system and have no interest in monthly subscription for software.
That said I see DXO has an offer until mid July and I have downloaded the trial version, how much better is it than DPP for a beginner? Should I just go straight to learning DXO and skip DPP if I can get SWMBO to sanction the expenditure? Just stick to DPP, the older version by the way.
I will confess to currently having no inclination to remove branches from pics, or do much more than crop slightly and straighten horizons after releasing the detail that seems to be locked up in the raw files.
If my current direction is blasphemous to you my apologies, perhaps in the future I can learn to progress to your level, but for now I have accepted I have a PP problem the first step to recovery! ;D
Apologies for the length of post.

Cheers Graham.

Canon General / Should we tell them?
« on: June 25, 2014, 08:04:48 PM »
Hi Folks.
I was in France for the D Day commemorations and went to several ceremonies and events, I couldn't help myself, I found myself explaining to people that if they turn to the P setting they wouldn't have to keep pushing the pop up flash back down when taking pictures of things well outside the range of the on board flash and that they could take control of the flash with the release button on the front of the body! Should I have done it, the people did seem to be grateful for the input, a couple even asked for more advice, I recommended coming here rather than trust me! ;D
Should we tell them or just leave them be if they don't ask?

Cheers Graham.

Hi Folks.
So to set the scene, we are at a car show, showing our cars. The misses says to bring the camera if you want some pictures of birds, this hedge is teeming with life! Camera is a 7D with a Meike grip.
I have some custom setups so selected one, fire off a few shots, review, decide I want spot metering, press the button, nothing, press other buttons on the top, nothing. Still able to take picture, just locked in to settings. I know I'll use the Q menu, nope nothing except the DOF button and AF on working! Ok drop the main batteries, switch on to drain circuits press shutter button. Switch off batteries back in, power up, same thing. Switch off switch on battery grip, nothing changes. Great I need this in a couple of days! Check lock switch is not set to lock, though I think that only disables rear control wheel cycle the switch on the battery grip on and off a few times, all is back to normal, I breath a big sigh of relief.
So if all the buttons stop functioning and you have a grip, probably especially a third party grip this might help.
For once I'm not in need of help, just trying to give something back!  ;D

Cheers Graham.
