    If we can crop for being slightly askew, can we crop/transform to correct for perspective distortion also? Or must the distortion of the wide angle be made to stay apparent? I have a couple of images that were shot with about a 12mm wide angle on a 10D or 12mm x 1.6 mag factor = 19.2 mm but the shots have been corrected in PS for perspective distortion - otherwise they are full frame - Is this OK?

    This is what they look like.... all with 12-24 mm Sigma zoom at the wide end

    cropping to correct distortion
    yes, but minor cropping only. i understand the need for this and i'm okay with it.

    remember folks the intent here is to be a hard-ass on purpose :D becuase we want to compose with the viewfinder not photoshop.

    to reiterate: minor, very minor, cropping to correct horizon or perspective is OK with me.

    thanks for the heads up, pf!

    How do I use the Free Transform tool to get the right perspective on life, and is that considered a minor adjustment?

    Andy, for once, I have to disagree with you: never, ever, ever call it a crop factor within a contest that has a no crop rule!!! rolleyes1.gif

    Its a multiplier, suffice to say, the CMOS chip in the Drebel is not the same size as a 35mm film, and the result is this factor. Ginger, I have to admit, sometimes your posts get too long for me so I skim, but there's no mystery or halving and subtracting 9, its straight up:

    (focal length) x 1.6 = (corrected focal length)

    back to trying to catch up...

    My camera is very bad with this particular thing. I got the camera the day before I left on my vacation last summer. I took lots of pictures of churches and towers in Italy. I was shocked to see the warped images on my computer when I returned. I finally learned about this tool.

    Click on Image> Transform> Distort. Then pull the top corners of the frame out until the image is straight. There really is no cropping required. You lose a tiny bit of the image on the sides, that's all. Now, I do this in Photoshop Elements, but I assume Photoshop is the same for you other guys.

    This is a wide angle challenge, and that shot was not a wide angle. As much as you like the picture, it doesn't fit the theme & criteria. So the facts are academic, and for a reason.

    Thanks for humoring me & sticking to the challenge rules.

    Ok, do you mind if I get to it, when I get to it. I am sitting with papers all over.

    I will take it down and now. But I was waiting for the results of the Challenge, which I would assume you could understand, and I undertook to collate and put together all the tutorials I have collected, so I would have some order.

    But to humor you, anything.

    I never had this problem with my Tamron lens. There was hardly any distortion at all. I really think this is a defect with this camera (Olympus c5050z).

    Here's a composit with the before and after. Look at that *bent* pillar on the left!

    A very good friend of mine took a trip to France last year and took a bunch of pictures of doors ... houses, buildings, whatever grabbed him. I've been hooked ever since! I think we should have a door challenge :D

    Nice shot.

    I would like to use the wide opportunity to try shooting crooked and converging bldgs. Most of ours aren't that big, so I probably won't. I have some shots of the bridge that need to be "fixed", but I have enough others that don't. Learning how to fix them is not as easy as picking another one.

    I just wondered if anyone else had thought of using the distortion, rather than fighting it.

    I think this photo has great mood. It's been 20 years since I was in Great Britain, but this brings back strong memories, smells, sounds ... I think that maybe that's partly what makes a great picture. Something that provides an instant connection for the viewer.

    Great shot!

    Quiet Falls... Wide angle.

    Took the boys to Busch Gardens again today, and while getting ready to leave tonight, decided to grab my camera and take a few shots.

    200asa 4 second exposure, ambient light source from the park, 8.9mm/14.24mm

    "Quiet Falls"

    Pathfinder, I love the door shot, also think doors would be a good challenge...

    Ginger Very nice waiting for Sunset... Nice color.

    This is going to be another busy challenge...

    Hey Ginger... He does look sad doesn't he? Money doesn't buy happiness? What does it look like without the PS blurring? I wonder at the background...

    See you're up late too... I'm heading down for the night now, though.

    Gubbsie, I really like this. I like the backlighting and the shape. Quite a lot of pure black in the foreground?

    Thanks Sid,
    There is a huge dynamic range, I did shoot it in raw though, so I'm sure I can get more out of it. Some guidance on blending different exposures would be really helpful... I'll check out the "hall" later on
    Thanks again

    Thanks Simone, It was a very hot day, so I did manage a drink too, a very cold "Amstel" coincidently.
    I don't want to do too much, just a hint of detail in the foreground, If I can work out how to do it :D

    Sorry Lynn and Digismile, I was working backwards, thanks for the comments thumb.gif

    The composition is better. The background seemed busy, but not busy enough...............if that makes any sense. I think this is a better photo than the first one. I am very tired and not thinking well. That day, for some reason, I was putting everyone, thing, in the center. This is not.

    Suggestions needed
    for outdoor photography: have no indoors, not for exhibit. So need suggestions on
    photography in blah, very heavy rain. The storms a comin'. And I am not kidding, I can't go 3 or 4 days and no photographs.

    ginger

    That was short and sweet.
    Suggestions needed for photographs, wide, in heavy rain conditions.

    Probably the rain will flatten the ocean. Less dramatic rather than more. I think this is more of a flooding type, dripping through the ceiling storm.

    Don't want to call photographer's anonymous......... don't know their number.

    Sounds like a good time to go to the mall and brush up on people, candids, portraits, see if you can catch a shop lifter
