    Help - greasy mark on 5D sensor!

    in Mirrorless Digital Cameras

    Posted

    Just went to clean the dusty sensor and my ViibleDust brush has left a

    greasy 'smear' on the sensor... i must have touched someone's hand or something.

     

    What's my best course of action - back to Canon? Or is there a suitable

    consumer product that can remove this?

     

    f22 image is below - makes me go cold to look at it. I've only had the camera

    a couple of weeks!

     

    Thanks for all help!

    Can't access my external hard drive

    As long as data isn't important and you are running XP or 200, try the following... it MIGHT work:

     

    1) boot up PC and HDD

    2) unplug USB cable to HDD

    3) wait for the 'bi-bong'

    4) plug it back in again (kep powered up and windows running)

    5) wait for the 'bo-bing'

    6) try re-accessing

     

    I've got to say it's more likely that you've either got a corrupt sector or a corrupt partition which is (in my opinion) a reason to reformat and start again.

     

    I would also never trust that drive again and, personally, stick in the bin - unless you are very unreliant on it.

     

    Sounds as if you have a very sensible backup strategy, as you aren't entirely reliant on this one - nice one.

    Flat Panel Monitor.... good for color management and digital photography?

    Make sure you buy an LCD with all the adjustents you need (eg. RGB correction, contrast, brightness) as some only have a basic gamma correction slider.

     

    As with CRTs, there are good, bad and ugly in LCDs... I had a couple of shocking Dell monitors that were so bad I gave them away. I now have a Philips 200W that is pin sharp and easy to calibrate (using a Spyder, in my case).

     

    Be aware that it's your video card that defines what resolutions are supported and a new one could be pretty cheap if you aren't interested in a mega-gaming solution!

     

    I also suggest getting a card with either 2x DVI outputs OR a DVI (for main monitor) and an analogue for a secondary monitor. a second monitor is incredibly useful for viewing software toolbars, image browsing software, keeping an eye on email etc. etc. You probably won't be able to calibrate both monitors (unless you have dual video cards) so you will need to pull any images onto main monitor before looking at them with an eye to colour...

    5D B/W images... can they be bettered?

    in The Digital Darkroom: Process, Technique & Printing

    Pam - that's nice looking conversion...

     

    My camera B/W settings are out of the box (3, 0, N, N)... to be faire, the original was quite dark (I didn't exposure compensate in RAW conversion deliberately, but it was set to Auto and did add some)...

     

    Perhaps my conversion technique just needs to be better! At least by shootin RAW + JPEG I've got the options (that was the thinking, anyway)

    Sorry to be a dullard, but I can't post any samples until I work out how to do so... give me a little while!

     

    To answer question re. conversion techniques, I have tried two:

     

    1) open colour RAW file into PSCS2 with white bal correction and a linear curves setting, add a levels adjustment layer, then add a black nd white gradient map layer. Adjust red, green and blue levels individually until visually happy with contract and tone, then flatten image. Finally convert to grayscale from RGB.

     

    2) open image, go to chanel mixer, set to gray, adjust channels individually as above. change image to grayscale.

     

    I admit it's pretty basic - I'm not an advanced PSCS2 user and I haven't tried selectively adjusting images with dodging/burning etc. yet...

    5D B/W images... can they be bettered?

    in The Digital Darkroom: Process, Technique & Printing

    I've not long had my 5D and have been playing around with shooting RAW + Mono

    JPEG shots. So far, I haven't been able to better the internal B/W JPEG

    conversion the camera does with PSCS2 and channel mixing conversions on the RAW

    image. In fact, I reckon the B/W images straight out of camera are great!

     

    Am I wasting my time? Should I just accept that the Canon alogorithm does it

    realy well and be happy that my B/W workflow can be some far reduced?!

    Silly question: How do I take picture or sky using xti

    in Canon EOS Mount

    Posted

    Any object or surface with low contrast and/or no defined edges for the AF to pick-up will provide focusing issues (on any camera that I have owned)...

     

    I would suggest either using manual focus (set to infinity will be a fairly good bet for sky unless you are trying to capture some very low altitude clouds) or to aim the active AF area/point at an edge of the object/surface at a suitable distance and then recompose for the final shot... eg. at the edge of a well-defined cloud, or a light switch on the wall you are trying to shoot.

     

    If there are NO objects at all, I think manual focus will be your only option...
