I don’t know if you ever watch the Joe Macnally video about grabbing your camera? well this is a way to refresh your memory:
Here’s a neat tip for digital photographers trying to shoot at slow shutter speeds without image-stabilized (IS or VR) lenses. Actually, it can even be helpful for those using IS/VR lenses when you’re really pushing the limits of hand-holdability. Scott Kelby talked about this during his photowalk Lightroom free webcast, but I think is good idea to keep talking about it and adding a few details.
So, here the steps:
- Set your camera to burst mode.
- Frame your subject
- Brace yourself as firmly as you can, and squeeze the shutter button gently.
Hold the shutter button down so that you fire off a burst of about 3-5 images. Odds are, once you get back to your computer and examine the images, there will be “one image” that’s considerably sharper than the rest. Delete the duds, and keep this good one!
The “downside” is obvious you will use up a lot more space on your memory cards. If you’re shooting in JPG mode and want a quick way to tell which image is the sharpest, just look at the file sizes. The one with the largest file size is nearly always the sharpest shot. This is because the JPG algorithm tries to preserve detail the sharper your image, the more fine detail is present, and the less the JPG algorithm is able to compress the image.
Incidentally, this is why high-ISO JPGs are larger than low-ISO JPGs of the same scene ñ the higher noise in the high-ISO image adds lots of fine detail, so the image can’t be compressed as much.
Of course, just like real IS/VR this technique only helps with correcting for camera shake. A moving subject and a slow shutter speed will still result in motion blur in the image. Example here:
This are my 2 cents, remember, learn from the Masters (Like Joe Macnally) and your picture quality will be increasing!

Hey Folks;
Well let me put it this way!, IF YOU WANT TO SEE THE MOST AMAZING AND EXPENSIVE CARS IN THE AREA! just go to Cars And Coffee in DuPont Registry in St Pete. I always got jaw dropped with this amazing machines, this last Saturday was a Alfa Romeo, saw the car first over a Formula One TV broadcast but never thought I can see it in the States, well here it is the 8C Competizione, a beautiful car.
Another car that caught my attention was the small but bad ass Lotus, again, what a superb and perfect design!
No more to say the pictures. Oh almost forget, in my rush in leaving the house in the morning, forgot to change my camera lens, ended using a wide angle Sigma 10-20, results pass my taste so I am happy,
Enjoy:

We probably all know about the exposure triangle by now. Pretty basic stuff you learn when you’re first getting into manual. And if you’re just learning, you may be wondering what the point is in obsessing over your ISO, aperture and shutter speed. So indulge me as I explain the triangle sub-headings:
Aperture – Depth of Field
When I learned that there were lenses that were ‘faster’ than others (meaning the aperture can open widely), and that this was required for good photos in low-light situations, I thought ‘great! problem solved!’ Well…problem NOT solved. Why? Because opening your 50mm f/1.4 right up to 1.4 now causes issues with very shallow DOF (depth of field). So if you’re shooting a wedding, perhaps, and your plan is to just open your aperture up, you better have a plan B. Because at some point, the groom will be a smudge in front of the bride or the bride will be holding her bouquet in front of her and the focus will fall on the wrong thing. So simply opening your aperture isn’t going to be enough to leave you other settings as they are. Point? When adjusting aperture, don’t just think ‘more light’, also think ‘depth of field’.

Shutter Speed – Sharpness
When first learning about the exposure triangle, every setting was explained to me in terms of how it dealt with light: aperture lets in more or less light, shutter speed lets it in longer or shorter, and ISO is how sensitive the sensor is to light. But like in the example above, there are other factors when considering your settings. With shutter speed, it isn’t only the length of time the shutter is open that you have to think about. Particularly in low-light situations, using a too-slow shutter can cause camera shake from your shaky hands or motion blur from moving subjects. And this all leads to blurry photos, soft edges and no sharpness in sight. Inside, use as fast a shutter as possible while still being slow enough to fit into your triangle. And if you can, invest in lenses with VR (Vibration Reduction) because this helps you to create sharper photos when shooting at slower shutter speeds or long focal lengths (far zoom) when your hands may be shaking. The short of it? Shutter speed = sharpness.

ISO – Grain
ISO can be your best friend or your worst enemy. It’s the setting I compromise on last and not if I can help it. I really hate noise. I’m learning not to pixel peep and LR3 is so much better at handling noise than LR2 ever was. That said, just know that ISO isn’t a magic triangle-balancing number. You can’t just whack it up to 3000 and forget about the rest. You should know that higher ISO equals increasingly more noise/grain. And some photographers add grain on purpose, particularly when shooting or editing in B&W. Basically? High ISO = grain.

Hopefully, expounding upon these other factors to think about when choosing your manual settings will help you make more informed choices and better photographs.
Yes Nikon just announced new camera body (Nikon D3100) and several new lenses (AF-S NIKKOR 85mm f1.4G, AF-S NIKKOR 55-300mm f/4.5-5.6G ED VR, AF-S NIKKOR 24-120mm f/4G ED VR, AF-S NIKKOR 28-300mm f/3.5-5.6 ED VR) I think with this new addition, Nikon shooters going to have more options for their needs.
