I need some expert advice on this:

I have purchased many poses, but sometimes some particular poses have to be fine tuned...and that is understandable. 

like in the attached image...i have tried different parameter settings to adjust Vickys but so that she could sit properly instead of with her but raised in the air which is obviously not good...i dont know any other way of fixing this...

any tips are welcome!...

thanks for viewing.

The most realistic answer is the best:

Go sit in front of a mirror in the pose you want to pose V4 in, and look.

WHERE does your body Bend....Twist...

I never buy poses, I use my mirror.

Ps, from your example?? The right thight has to come upwards in order for the hip to go down.

If you sit like that???
What parts are pushing into the cussion?? And how are they bended/twisted??
Go, sit like that, and look.

And before you start posing, remove ALL IK you can find and throw them as far as they want to fly :-).
Euh, NO => NO LOL. The are a PITA. (at best)

For Poses and light... 2 things you can buy but rarely work out of the box.
I use my eyes and look at real poses and real light.

1. turn on IK for the feet

2. grab the hip group

3. Zrotate

The morphing tool is also your friend.

the vast majority of poses on the market are rushed, and dont have any consideration given to having hands/feet properly grounded on the floor (or on the figure if they are contacting it), much less any thought put towards physics/gravity/balance/etc.

but this is a product of the marketplace, where packs of '1000 poses' are seen as a great value. personally, id rather have 5 good poses than 1000 rushed ones.

"I never buy poses, I use my mirror."

a mirror is definitely essential for correcting poses, or creating ones that look natural.

You have to consider every pose that you can find and use only as a base for what you want to create.

Even the most well crafted needs some corrections and tweaks to suit the final result that you imagine.

I never used a pose as is, as Blackhearted said use a mirror or some photos as reference is the best choice.

...or a model if you can find one! :biggrin:

That is all Poser is about; To Pose :-)

Do you say; I am going to cook dinner? And then drive off to Mc Donalds? :-)
Sorry, internal joke.

Yes, a mirror is your friend.
Look at the bends and twist of your body, or from your model if you have one.
Girlfriend? Wife? Sister?

Ps leaving IK On for the feet would perhaps work for the left foot.
The right foot will fly-off when lowering or Z rotating the hip as is;

It may be just me, but the pose looks pretty good. Natural... The problem appears to be the scale of the chair. It has the proportions of a throne. Try scaling it down to 95% or 90% and she might sit more naturally.

I could be wrong and frequently am...

The chair is weird looking but it may be based on a real one that looks just as weird.  The seat part looks about the correct height, anyhow.  The pose does look really odd, though; I just bet anyone posed like that couldn't stay in that position for long without discomfort.

Edited to add: I almost agree with Blackhearted.  The "almost" part is the use of IK, which can frequently make the knees bend left and right in exactly the way they don't.  There are a lot of poses like that for sale, too; elbows and knees moving left and right.  There's a very limited amount of left/right movement on either of those joints and it's usually because there's some weight applied.  In theory, they should only be able to bend forward (elbows) and back (knees).  And while we're at it, there are numerous hand poses with twist applied to fingers or left/right movement after the first joint.  Bleah. 

I would agree with others that the best use for purchased poses is as a quick starting point or, if you are going to have a number of background figures, to save time on the ones the viewer won't be looking at too much. Having said that, sometimes you really do need to do something fast and a canned pose can do the job if it's of a good enough quality - as Blackhearted has said, quality over quantity every time.

I find that IK is a great boon for getting a little dynamism in a pose but for a seated or standing figure, I prefer not to use it. Instead I decide roughly how I want the figure and then start by positioning the hip. I then work down the legs (sometimes tweaking the hip if it's clear that I need to) finishing with the feet, getting them where I want them. After this I work my way up the body to the shoulders and then down the arms to the hands. Next I deal with the neck and then the head. You can use references (I've used a few old comics lately) but I find that they are of limited use becaust the furniture you have in Poser is not going to be quite the same as that in the reference, by doing things this way you will usually end up with something that looks natural to that chair because you are building the pose around it.

This done, I decide on the camera position that I want for the render. Once that decision is made I can start to tweak the pose, usually spending time on the hands - but only if they are visible, there's no point in perfecting what can't be seen. I try to pay attention to what is phisically possible for a joint to do but at the end of the day, if it looks right from the camera position that I have chosen, then I don't mind breaking a few rules/bones.

I agree with turning IK on for the lower limbs.  but then I would grab the hip and hold the shift key down, then try and pull the hip into the positon I want it in.

Love esther

IK is usually the fastest/easiest way to adjust poses.

step 1: please, for the love of god, ground the feet on the floor. my biggest pet peeve in poses is when the figures are floating 2" in the air.

step 2: turn on IK for the feet.

now you can twist the hip group to cock the hips, you can grab a foot and move it to the side or front/back, etc. if you raise/lower the hip youll bend or straighten the knees, etc.

the same can be done (to a far limited degree) with the hands. say you have a pose that has both of a characters hands on their hips, you can turn on IK for both hands and twist/bend the chest/abdomen a bit and adjust the pose. this is far easier than with IK off, and then having to sit there and retweak the hands/fingers all over again.

you can also use it to fix 'balance' in some poses. for example a standing pose where the figure is unnaturally out of balance to one side or another, just turn on IK for the legs, grab the hip, and Z or X translate it. without IK youd have to rotate the hip, and then go and bend/side-side the legs and try to get them grounded again.

no its not perfect, and no its not the answer to every posing problem -- sometimes the limbs will pretzel up on you. big deal, thats what CTRL-Z is for.

I think if you turn IK on for the hands too that when you move the hip they will stay on the arm rests of the chair.  You'll have to try it.

Yes Ester, correct, but the chair has some strange proportions.

The seat height looks OK, but the armrests and the backrest are way too high for a normal seating position.

hmm, maybe he could decrease the Y scale a bit?

of the chair that is hehe.

I'm perplexed, why isn't there any shadows cast by Vicky on the chair?

it's probably just a sample quick render.
