Well done.
Good, solid well framed/squared off shots at a tough shoot.
Good exposure and WB/colors look neutral like they should.
I really like how the stair, window and doorway shots came out.
The blue room is gorgeous.
Always a pleasure to view good shooting here
Note: Experiment with different cam heights; you can go from ceiling to floor, wall to wall to capture unique shots and still square them off if the lense is wide enough.
Shooting floor or ceiling level against walls, doorways or rails can be very effective when shooting stair cases.
Don't hesitate to -lose- the tripod and
guerrilla shoot; brace the cam on anything that gives you the shot you want.
A bush towel between the cam body or lense barrel helps to get a steady shot and keeps grim off the equipment.
This also frees you from the burden and restrictions of the tripod; you can grab a lot more images with much less set up time.
Takes a couple of shoots to get the technique down; don't be discouraged at first (it might all be a blur). Watched your breathing, brace your body too if possible and stay steady... and easy on the release punch.
This is my favorite shooting style.
A good, bright viewfinder finder (you need see it; keep a close eye on the edges and line the lense center/subject center by dead reckoning) on the cam helps a lot as does the weight/grips on a pro cam body.
Adding a battery pack to a non-profit cam body will help make it more stable and easier to hold.
You'll get some shots with shake; when in doubt shoot again. Deep breathe, again... keep the ISO setting as low as you can.
Done right 1/30@sec is doable and lower.
Invariably once you get this style of shooting down you'll get more unique keepers than is possible even with elaborate rigging or a tripod.
Usually best to square them off but don't hesitate to alter the cam angle/level if it's for an artistic composition that works to capture your art. The brain has a hard time processing 2D images that aren't square off and it generally degrades the image... spacial distortion can hurt.
Not always though.
Once you have good shooting skills like these and the basics down, bump it up a notch with niche composition shots.
Many times you wouldn't be sure it's a keeper until it's on the monitor and your brain goes 'wow'.
The brain knows good art when it sees it...
