Photos taken by Pentax cameras for tech. discussion - Season II

[restigate]

Base on the two photos you've posted, it seems like you're using the lens wide open (ie. with the smallest f-number/largest aperture size). Most lenses don't achieve their optimal sharpness until you stop down a little. Try shooting at f8, there should be a difference.

And having the subject blurred somewhere can just be due to the limited depth of field (DOF), a "problem" that PnS cameras don't have. If you need to have more of the subject in focus, you may need to take it at a different angle such that the subject is more flat or facing the camera. Or stop down to achieve more DOF.

Don't worry, keep experimenting, you'll get the hang of it.

Thank you very much for your kind advice Gengh bro! Very much appreciated.

I have another question. I found that when shooting in low light, if i shoot in the shutter priority mode with 1/125 i can get clearer and sharper pic.

Any better suggestions?

this is probably becos in low light your camera will naturally choose a lower shutter speed if you're using low iso settings. this will lead to loss of sharpness if you can't hold your camera steady enough during the length of the exposure (camera shake). To reduce camera shake due to low shutter speed, you can either:

1) use flash to increase the light in the scene
2) choose higher iso so that you can use a faster shutter speed - this can be done in manual, Aperture or shutter priority modes.

I believe you're using shutter priority with auto ISO. What you're doing is giving yourself a lot of buffer with respect to the 1/(focal length) rule. If you make sure you have good hand-holding technique, at 55mm you should be able to use 1/30 or even 1/10 (probably quite hit and miss) with SR turned on. 1/125 is a bit overkill (unless you're trying to freeze action).

If the scene doesn't move, like night landscapes, nothing beats using a tripod and low ISO.

Lower Peirce Reservoir recently

K-r with Sigma 10-20mm f/4-5.6

sorry for digging up this old post! fantastic pictures as always! :thumbsup:

how do u make the water so clear so that you can get see the rocks beneath the surface? i always struggle with this.. did u use a CPL? becos I always thought this would lead to uneven polarisation with ultrawides? :dunno: cheers!

Yesterday sunset was beautiful.. k-r with da15

Looks like you captured a unique day indeed.

Took this on the 22nd May... no pp done, straight jpeg from the camera

Yea. The magical sky only lasted for like 5 minutes. I was just lucky..

I just positioned myself at the right height.

I don't own any CPLs. Hope this helps.

Here's one from the Cosina 19-35 I got from someone here.

 

[kengoh]

Took these after the Pentax Botanic Garden outing:

#1 Black Shoulder Kite

#2 this is the only flight shot taken with 500mm, really tough compared to 300mm handheld. :sweat:

#3 with prey.. poor rat. :cry:

 

[machiavellian]

woah, I see the bird's tongue has a life on its own! O.O

 

[seion]

I was able to shoot also the magnificent sunset last sunday at lower pierce reservoir
and only need minor PP.
here's one and more HERE

k5+DA15mm

This is real nice . Simple subject but great feel

Lovely! Curious but how did you manage to find a white chair handy?

how interesting... will try different angles next time. thanks!

Try to always stand up, squat down, go low, etc. After a while you would get the idea of how different heights can help with composition. Most people just stand and shoot.

Oh, I really don't know - there were loads of them sitting around the beach, so I just pulled one, planted it in the water, then replaced it in its original position..

Simon - thanks. Must say the 19-35 is a lot sharper than I thought.

it just makes a world of difference with the chair there. inspired touch bro!

I will try your suggestions. Hopefully will have better photos to post here soon.
