Lenses / Re: How to clean lenses ?
« on: August 23, 2013, 10:43:49 AM »
Still no one answered my question lol. Is it safe to clean the lens and LCD screen with alcohol wipe ?

alcohol should be used sparingly. On glass it should be fine, although I am not sure how the coatings react over long term use.  On plastic, alcohol can leach things or alter the plastic, depending on the plastic. Perspex becomes turbid after long term use.  Given that one does not know how the plastic of the lens or the body reacts, it's probably better to avoid it. Also, the LCD screen, I am not sure if that is actually glass or plastic.
I have a screen protector on my LCD, so just wipe it with a cloth (and some breath) if necessary.
For the lens elements, first rocket blower to remove dust as much as possible. You don't want to wipe the lens when scratchy dust particles are on it. A brush can help release particles. Only then I use microfiber cloth or clean cotton cloth to wipe, again with some breath if necessary. If there are some persistent grease spots, only then some lens cleaning fluid.

+1.
Taught to do it this way on a Short Digital Photography Course by a Professional.
Not needed Alcohol yet. Well not for the Lenses anyway.

Beware. A guy I knew in the military was told to clean his tape heads with Alcohol,
he tried it with Beer! Go figure.........

Fine, if you are standing among zebras.
I beg to differ. You'd very easily lose the lens then!

yep sometimes it greys it out, try this, before going into apply image, get into the channels panel and pick the A channel(or any single channel) so its the only one visible.

edit: And yes, both methods are doing essentially the same thing, remove all info of the selected channel, you might want to duplicate your layer first!
Meli,
got it now. Works perfectly. Thanks.
Cheers Brian

from image menu > apply image > bg layer >channel A, set it to subtract (numbers in the side should be something like 2/128

Alternatively, just fill the A channel with 50% grey
Hi Meli, thanks very much.

I assume through this that I am removing all information from that channel?

Last night I couldn't get it to work as "subtract" was greyed out, I'll need to look into that.

Site Information / Re: Can't upload photos
« on: July 03, 2013, 12:33:52 PM »
I am perplexed.  After posting successfully a couple of days ago, I can't upload photos to the forum for about 48 hours.  I can post words but no pictures.  I tried JPEG all less that 4096 MB (quite a bit smaller, in fact) using multiple pictures and cannot get them to load.  I have tried both Firefox and IE.  I've disabled and re-enabled cookies, pop-up blockers And turned my antivirus software on and off.  When I load an attachment and click post, I see a message "Waiting for Canon Rumors" but then the page goes blank dn nothing ha been posted.  I know this is a photo forum and not a computer forum, but I'd appreciate any ideas from out there. 

I am not a geek (sorry) but I am fairly adept at using a PC and making adjustments to the OS and the device.  FWIW, I've been using a Win7 Pro with 8GB mem and have lot's of disk space.

Thanks.  I've seen something like this posted here before but could not find that thread.

There is simply something wrong with the JPEG, and the CR site cannot display it.
Try other ways of creating the picture, or converting it,  Its just a pity there is no error message.

I dont think the 800x800 is valid any longer. I've posted larger pictures:

Hi,
I'm trying to do something pretty simple, as usual I can't get it to work. While working on a picture
in LAB mode, I turned off the "A" channel, and it was a pretty nice effect. So I thought, I'd like to
save a version of this picture with those colours, unfortunately that doesn't seem to work.
You can switch them "A", "B" or "Luminance" off, make them invisible I guess, but they are always
saved.
So anyone any ideas how I can do this?

Cheers Brian

The Eurasian Sparrow hawk is shot from 5 meters, 100 iso and 65 mm (in my garden). I did only a crop from landscape to portrait.
The Common Kingfisher is shot from 13 meters, 80 iso and 1200 mm. The height was 2.2x more. So from the 12Mp, 2.5Mp is left?
Hi nice shots. So did you happen to be 5m away when the Hawk landed or did you manage to move there?
Cheers Brian

Black Vulture

Black Crowned Night Heron (Canon 1Dx, 300mm 2.8 II)

I love your bird pictures MRLinVA. Nice and sharp. Looking forward to see more of them. :)

+1, very nice. Is it me or does that BCN Heron only have one leg? :o
Perhaps a pirate..aarrrgghh :)
We had a Blue Tit in the garden which we thought only had one leg, it would lean against things.
And on the ground hop about on one leg, using a wing to steady itself if it was in danger of falling over.
Sometime later we did see the leg a few times, so it must have been injured somehow.

Obviously we called her "Eileen"  8)

Nice Captures Serendipidy, The Eye on this Bird is just Tack Sharp, as well as a little scary, well done.
"Scary"?    Downright spooky if you ask me.
If he does leave you sometime, do you think his parting words will be

" so long, and thanks for all the fish!"  8)

Rosedale may be nice. North Yorks Moors Railway Steamtrains.  Scarborough Castle? 
Hole of Horcum (sp?) maybe.

Very young Thrush.
Cheers Brian
Lovely! You must be feeling like a proud grand dad ;)
Sure am. There's six of them though and that nest is getting very tight, so they'll be out soon.
Still, I hope they'll cost me less than my own kids did (still do).:-\

Went out today to try and practice/learn BIF. Tried the suggestions made by this forum and I'm starting to improve and get some keepers (I hope).Best 3 out of about 60 tries (in some shots, the bird wasn't even in the frame :(). 7D, 70-200L/2.8 @100,130mm ISO100, TV 1/800s, Aperture 2.8-4.0, hand held, cropped, DPP. Comments to help me improve are welcome. Thanks. :)
Well I think you are getting there. Keep it up. And I'm jealous that you have a pet Heron!
Cheers Brian

Sorry rpt...I didn't realize the gravity of the situation 8)
Ha ha ha  ;D
Serious matter this defying gravity stuff. This guy hasn't got the hang yet, or it doesn't work when you are wet. Whatever, he's still holding on. Didn't Douglas adams say "you just need to forget to fall down"?
