Lens conversion and buy a pentax m42 50/1.7 lens.Īs a Canon user I'll echo Peter's observation, and the recommendations to invest in a much better lens. get a canon 50/1.8 or a sigma 50 or 105 lens and you will be Lens in the market and as such you have to replace it with a decent I see that you are using the canon kit lens. Get it right to start with and you wont nee PS. Shutter speed and aperture have no bearing on the distortion as long as you expose correctly. There is nothing magical about this length with this problem in mind and longer would be better.Īlso keep everything square, picture centred and square to the camera left to right and up/down. The nearer top the camera the picture is the more distortion you will get, so get them far away and as someone said shoot at the longest focal length is using a zoom. In fact as long as you can physically get your hands on and reasonable be able to photography the pictures without them having to be in the next field. Well a few of the posters hinted at the longer focal length lens. It is incredibly finicky and cannot be done in one correction if the frame is rectangular (rather than square). I found this question interesting because i work in a professional photography business amd some years ago i also had to photograph some large framed prints for our website and encountered the same problems as you have encountered.įirstly correcting in PS (and I am well versed in using the programme) is NOT easy. And why are the first three or so replies administring after cures when surely getting it right in the first instance is most important. The quality of lens has nothing to do with distortion so delete that reply. I'm not very impressed with the answers that you've had so far. It's still a pain to fix, better to use a low distortion lens like a macro or a 50 to begin with. Now that you've taken photos that have distortion, how to fix them? Photoshop CS2 has a lens distortion filter that lets you fix it. Macro lenses also have very little distortion and make a good choice.you don't have to use the lens up close, most macros work fine for far away distances too. Most 50mm lenses have almost no distortion and are generally the best lenses in any company's line. Also, zooms distort more than non-zooms, and wide angle lenses distort more than standard lenses. Higher quality lenses generally have less distortion than cheaper lenses (like kit lenses included with many digital SLRs). Depending on the lens design, you may see the lines bow inward and some lenses make distortion that makes the lines bow outward. Nearly all lenses have some linear distortion. Without seeing one of your photos, my guess would be that it's normal lens distortion. What I do I cannot seem to resolve this problem. Photos of artwork with this unintentional effect because no matter Two sides of the painting appear to warp outward. With the equipment I'm using I cannot seem to avoid Have the camera setup on a tripod approx 7 feet from the subject I am an art dealer and I photograph 24"x36" oil paintings daily.
