Hello All
A few more snaps! A question, why when I am using the same settings for all of my photos and the same light source and virtually the same position for the subject do some backgrounds come out grey and others white (they are white). :confused:
Cheers, Ken

Very nice pictures of a first generation Q there Ken.

Gerard, the knife in Ken's pictures is a very early Q. The later ones have a flat handle like the "Kona" one in the picture below, rather than the "3D" look of the early ones. They also have an additional small cross-pin to prevent the lockbar from being raised too far. You can see that in the shot below as well.Gerard Breuker wrote:I was going to say that the pictures of the SpyderQ are nicer to look at than the real deal only to discover that mine has a different handle somehow.
It is just flat instead of 3D if that makes any sense. Another SpyderSecret I wasn't aware of.

Ken, the pictures were taking with automatic exposure, and that resulted in the difference. On the Civi, the blade was probably reflecting a lot of light and therefore the camere tried to compensate. Try to shift the blade in such a way that it's not reflecting so much.UK KEN wrote:Hello All

The exposure on the Q was F3.5 with 1/60 (according to the exif data in the JPG)
On the Civi it's F6.7 with 1/180
That's almost 2 stops in aperture, and 1 1/2 stop in exposure time, resulting in a 3 1/2 stops difference, and that's the reason that the Civi picture is a lot darker.
You should try a manual exposure. You're camera will probably indicate how much you have over or under exposed according to it's own measurings.
I normally expose pictures with a white background 1 or 2 stops, and under expose pictures with a darker background 1 stop.
Good luck, the pictures are getting better everytime.

some more info - when doing manual exposure, set the aperture to F8, and only adjust the shutter time to get the right exposure. (assuming you have a tri-pod to deal with long shutter times).
With a high aperture number, you'll get more depth of field.
The first pic of the Q has a low aperture number and you can see that the image get's blurry at the back. If you use a higher aperture number it will be sharper.

Thank you!

I'll have to give that a try. I still have a lot to learn!

Nice shots and nice knife!
Did you use a great zoom factor or the macro-mode on the pics with the grey background? That could also be a reason. Macro shots always need more light than normal shots. Not easy to explain (I've never been good at physics :o ), but there's plenty of info regarding that on the web.
You're improving a lot! Just an idea... Try to shoot a knife on a background other than white. These are IMO the most difficult pictures. Look around in the house and you'll be astonished what can be used as a background. Especially if your wife likes to do handicrafts :D
I found out that most knives will look better if you shoot them on a background that has much contrast to the knife. Compare the pics of the LBK and the C28PBK on my site. That pretty explains what I mean :o I have to take at least 5 or 6 pics of my knives again for that reason. My only problem is that I ran out of backgrounds...
Taking pictures of reflecting objects on a bright background often "confuses" the camera when it makes the measuring for brightness and white balance. Using a "grey card" like I mentioned in the other thread is the best way to handle the white balace issue but colored backgrounds are also a simple way to move around that problem. They also tend to give the picture more depth compared to a white sheet of paper.
At the end it all boils down to lots of experiments :D
