The matrix will be out of focus and the picture will become blurry and unclear. You would need to increase the focal length (which is not possible with a single lens, but quite possible with a Zoom lens that has multiple of them) But there would be a practical problem: Since the camera is now "open" too much light will enter from the side so your picture will be "white" anyway  doh.gif

Let's talk about fixed 50 mm lens. Why the picture will become blurry when i move the lens (I would like to skip practical problems now. I would like to understand the principle)? If I've moved the lens didn't I increased the focal length in accordance with the previous theory?

Kadangi jau lyg baigėte ginčytis tema, kurios aš nelabai suprantu, parodysiu savo pirmąjį bandymą su hdr:
nuotrauka ne kokia, galite nevertinti, rodau rezultatus.
Taigi turėjau va tokis dvi foto
Pirmoji peršviesta - matosi šešėlyje esantys augalai, bet pastatas visiškai išdegęs

Antroji per tamsi, augalai juodulys, na pastatas matosi.

Pirmuoju atveju fokusavau į augalus, antruoju į pastatą (berods).

Po 2 min. pasižaidimo su PhotoImpact rezultatas gavosi va toks:

Principas kaip dirbtis lyg aiškus. va dabar supratau kam fotoaparate galima pritaikyti funkciją kur daro 3 kadrus - šviesų, vidutinį ir tamsų.

man nerodo nuotrauku verysad.gif

The 50mm is a property of the lens. It doesn t change whatever way you move it. The 50mm are defined via the way parallel light behaves that comes from an infinite distance. Obviously no real world object (like the face of my wife) would be like that. To focus on real world objects you always need more than the focal length.

If I focus in the face of my wife and lets say she is like 6 meters away I can not keep the matrix at 50mm, I need to move the "focal ares" - obviously I dont want to focus her face on a "point" - further away. (But I need to admit I had to draw a picture for myself now first to get it right in my head again blink.gif )

Dajavu, gerai pazaidei. Nors siuo atveju ne fotografas, o programa susisluoja laurus smile.gif O tie 3 kadrai yra vadinami breketingu (gali ir 5 daryti).
Kur ir uz kiek pirkai PhotoImpact?

OK. What does the focus ring of the lens which actually moves a single lens or a lens group inside?
