Bottom limb bend

[DC]

I've noticed many times that in the full draw pictures that the bottom limb seem to be bent more. I know it's not faulty tiller because of the people that are posting them. Is this a camera angle thing or hand position or am I imagining it?

Bottom limb is shorter as some of it is taken up with the grip, this often results in it having to bend a little more to give an even tiller. Conversely some people leave it stiffer to help compensate.
There are also some camera angle issues with bows... if you photograph leaning in a corner, the lower limb gets foreshortened unless you bend down to get the camera level with the grip.

   Del is correct, but also string angle plays a huge part. Because of nocking point and an arrow pass above center the string angle on the lower limb becomes sharper...

i dont really measure the positive tiller at brace,, self bows that are not so straight will fool you,, I like the positive tiller to be at full draw,,, if the bottom limb is weaker at full draw I will adjust it,, unless it is just shooting great,,, and it will have the appearance of being a bit stiff,,

I noticed this on some of my first bows too. Looked fine on the tiller tree, but changed in my hand.
try to get your last few inches of draw with your bow in hand, in front of the mirror or take photos.

I use my wife, she has been around a lot of good Bowyers. And, I usually leave my bottom limb a little tighter then the top, it takes more stress over the long haul.

Yep.....That right there helped my tillering efforts 100%........the last 3-4" in the hand, with my wife taking pictures.

  If I understand right, this is really often just an optical illusion.  The bottom limb can be bending less than the top and still look like this.

I do try for positive tiller, but often, as mentioned with bows from imperfect staves, I can often feel better than see it.
