Corectarea Distorsiune Barrel of & Ultrawide Lentila Wide

I love to shoot with wide and ultra-wide lenses.mi place pentru a trage cu i ultra-larg lentile largi.And I just lovethe Canon 15mm Fish Eye lens that I have.Si-mi place doar Canon 15mm lentil ochi de pete care le-am.Its anamazing tool to stretch your photographic creativity.Su un instrument uimitor s se ntind fotograficecreativitatea.The barrelling and the huge depth of field of the fish eye lens often produce images which stand outfrom the rest.Barreling i adncimea mare a cmpului a lentilei ochiului de pete produc adesea imagini care sedisting de restul.

This picture of the Petronas Twin Towers in Kuala Lumpur, the Tallest TWIN Towers in the world, is one of myfavourite pictures shot with the Canon Fisheye.Acest tablou de Gemene Petronas Towers din Kuala Lumpur, celmai inalt Twin Towers din lume, este una dintre fotografiile mele preferate shot cu Fisheye Canon.

There is an obvious convergence of the tops of the twin towers which is a characteristic of wide angle lenses.Exist o convergen evident a Topuri de turnuri gemene, care este o caracteristic de lentile de unghi larg.This"barrelling" effect is akin to the volksvagen car - you either love it or you hate it.Acest "barreling" efect estenrudit cu masina volksvagen - v fie place sau l ursc.But I'm sure you'll agree that it is slightly "different" TwinTowers picture from the zillions of pictures which zillions of tourists have probably shot of this famous building.Dar eu sunt sigur c vei avea de acord c este uor "diferit" Twin Towers imagine din zillions de imagini carezillions de turiti, probabil, au mpucat din aceast cldire celebru.

When I posted this picture in POTY last year when POTY was DL (Digital Life), most people commented that Ishould debarrel the picture.Cnd am postat aceast imagine n POTY anul trecut, cand a fost POTY DL (DigitalVia), cei mai muli oameni a comentat c ar trebui s debarrel imagine.Of course I didn't debarrel it !Desigur, nul-am debarrel!I wanted it to look like that.Am vrut sa arate asa.And I kinda liked it this way.Si am cam plcut nacest mod.

But lets say I did want to debarrel and remove the pin-cushion effect of a wide angle lens.Dar haidei s spun cam vrut s debarrel i scoatei-pernei efect PIN un obiectiv cu unghi larg.How would I do it?Cum mi-ar face?

Well, Photoshop has several tools to do it. Ei bine, Photoshop are multe instrumente care s o fac.You could usethe Transform/perspective/skew/distort commands to carefully straighten the towers.Ai putea folosi Transformarea/ perspectiv / oblic / denatureze comenzi pentru a indrepta cu atenie turnuri.Its quite an involved process tostretch and pull and squeeze and stretch again to straighten it with photoshop.Sa implicat destul de un proces s sentind i trage i strngei i ntinde din nou s-l ndreptai cu Photoshop.It will take a good part of half an hour todo it manually.Se va lua o bun parte de o jumtate de or pentru a face acest lucru manual.And when you'refinished, the image would have probably degraded significantly from all those shuffling of pixels.Iar atunci cndai terminat, imaginea ar fi degradat n mod semnificativ, probabil, din toate cele amestecare de pixeli.But it can bedone with Photoshop.Dar se poate face cu Photoshop.

There are many software packages out there that can do it in conjuction with Photoshop, although there are also

will have to rely on software.Dar aceste lentile sunt foarte scumpe, ne sraci fotografi amatori, astfel va trebui sse bazeze pe software.

After installing the plugin, loading an image and calling the PTLens plug in from Photoshop's filter menu for thefirst time, Photoshop will ask you for the directory/folder where you've put your camera profile.Dup instalarea

plug-in, o imagine de ncrcare i de asteptare PTLens techerul n meniul de la filtru de Photoshop pentru primadat, Photoshop va cere pentru directorul / folderul n care ai pus aparatul profilul tau.Then PT Lens behaves justlike any other filter.Apoi, PT Lens se comport la fel ca orice alt filtru.
