What happened here

[dpds68]

I put this shot up on another site and one of the reviews that I got complained that the onboard flash ruined the shot , but if you look at my Exif data the flash was not fired ant idea what happened ?

Sorry I should of put some more info , This was my first try at shooting in RAW and I used ISO 1600 because of another thread in here , I sharpened in DPP converted to JPG and cloned out a distracting pipe in top left corner in CS2 that's all that was done .

EXIF shows shutter at 1/160 on a 300mm lens. For handheld shots, the minimum shutter should be 1/focal length or, in this case, 1/320.

Exif Sub IFD

* Exposure Time (1 / Shutter Speed) = 1/160 second = 0.00625 second
* Lens F-Number/F-Stop = 63/10 = F6.3
* Exposure Program = manual control (1)
* ISO Speed Ratings = 1600
* Exif Version = 0221
* Original Date/Time = 2008:05:30 15:04:36
* Digitization Date/Time = 2008:05:30 15:04:36
* Components Configuration = 0x01,0x02,0x03,0x00 / YCbCr
* Shutter Speed Value (APEX) = 479850/65536
Shutter Speed (Exposure Time) = 1/160 second
* Aperture Value (APEX) = 348042/65536
Aperture = F6.3
* Exposure Bias (EV) = 0/2 = 0
* Flash = Flash did not fire, compulsory flash mode
* Focal Length = 300/1 mm = 300 mm

So you think that Camera shake was the problem what about the Metering Mode It's set to the default should I have used Spot metering ?

[Karl C]

It appears camera shake was an issue. As for metering modes, I would've used either Spot or Center-weighted (mostly like Spot).

[dpds68]

Thank you very much .

I was also wondering about the softness of the Tamron 70-300mm I have seen some very sharp shots from them but I think that I should change the Metering mode and I still lave loads to learn , This is my first DSLR it's just a few weeks old.

And since this is a 1.6 crop body, multiply the focal by 1.6 = 480, and use a shutter speed of 1/480 or 1/500.

As soon as I saw the picture, I said to my self - "that's probably movement of the camera during exposure".

And the OP's comment, "I used ISO 1600 because of another thread in here . . ", doesn't make a lot of sense. Use the lowest ISO you can get away with that will provide the f/stop and shutter speed the image requires.

I know nothing about that Tamron lens but here's a couple of review sites:

The Digital Picture (http://www.the-digital-picture.com/Reviews/)

Photozone (http://www.photozone.de/Reviews/Canon%20EOS%20Lens%20Tests)

Good luck

I realize as I look through some other shots that I was not steady at that SS at 300mm , I will now live by the rule of Shutter speed = 1/Focal Length inclusive of the 1.6 crop factor .

I'm sure the lens is fine. It is just a matter of understanding its capabilities and working on technique. Don't worry, we all had to start somewhere.

The metering mode doesn't have anything to do with sharpness, it only has to do with getting a proper exposure.

Very nice composition on the photo, by the way. Try not to clip off the top of the ear though.

Good luck, and keep shooting and learning! You're doing the right thing by posting the shots that don't turn out the way you'd like on here. The fine folks here can let you know what to do next time to get a better photo.

That is a good starting point, but proper technique is still important. Using a tripod or monopod can get around that rule though, when properly used of course.

[dpds68]

Thank you , with this site and lots of shooting I will be getting somewhere .

[dpds68]

I have a tripod that I used with my P&S it's a Radio Shack Targus I mounted it with the Kit Lens but haven't tried it with the 70-300mm.

That probably isn't the best tripod to use, but it should improve sharpness on slower shutter speeds.

[dpds68]

I am afraid the it will topple over with the weight of the 70-300

If it is that flimsy, then don't use it. You can always brace yourself to hand hold at slower shutter speeds of get a bean bag and set the camera on that. For very slow shutter speeds, you will want a remote shutter release. You can find them very cheap on ebay. Just be sure to get the right one. Canon has a different style connector for the rebel series and the xxD, 5D & 1D series.

Thank you DDCSD I will look out for a remote , what about the DIY's .

So in that light with a maximum available aperture of f5.6 and a minumum shutter speed of 1/500, what ISO would you recommend?

[dpds68]

^^ I guess it will depend on the light conditions ??

[Glenn NK]

Thank you DDCSD I will look out for a remote , what about the DIY's .

I believe you are OK with your Rebel; the XXD and One series use Canon's proprietary N3 plug, but the Rebels use a standard mini jack.

I would struggle with Av, and live with whatever shutter speed it would yield at ISO 1600, and maybe try 3200 (not sure the Rebels have that setting).

Or, if the kitten decided to stay sleepy looking, the tripod would come out.

Some times, the shot just isn't technically possible with the gear we have, and if we must have the shot, we live with the results. Life is great, but it's not always perfect.;)

[dpds68]

Thank you , that DIY remote shutter will be my weekend project;)

Hmmmm.... never thought of that, but I have messed around with my film rebel. I have a connector that I got with my Skyports that has a 3/32" plug and a PC connector on the other side that would fire the camera by shorting out the PC connector. Should be very easy to rig one up, really.

It is actually considered a "sub-mini" jack though. 2.5mm (3/32"). Regular miniphone is 3.5mm (1/8").

[DDCSD]

I just made a shutter release. You can see it here.
