Critique..Why is it blue?
HI
I just got around to finally shooting some pieces after much information gained from this board. Tthanks everyone!
Nikkon D70 shot in apeture priority mode F13
shot ourdoors on a very sunny day --my bulbs that came with the kit did not cut it.......too dark.
A black shirt.
The back of the tent was facing the sun.
The backround is a plastic light cover that has texture on one side and smooth on the other.
I shot in several AP settings starting from 11 up to 22.
and 2 in auto and macro, the AP was the best.
Why the blue hue??

I don't have a Nikkon, but have you checked the white balance setting?

Set your camera on M for manual and toy with the fstop. Take some pictures at different settings and see how they look. Start around 6 and go up.
Also, if you are outside you might want to set your white balance on shade if you are taking these in the shade which it looks like you are.
The same would go for your photos under the lights. Put your candle on M not A so you can adjust both the Aperture and the Fstop. The Aperture sets how much light is let into the camera and the Fstop or shutter speed is how long the light is let into the camera.
You should be able to take photos that are not to dark by setting your shutter to stay open longer. The aperture sets how much of the photo will be in focus.

Your background probably has a color cast to it and the bright sunlight is causing it to bounce off the sides of your tent, giving everyting a color cast. It does clean up pretty well in Photoshop by first doing Auto Color and then tweaking the colors from there to take away the blue. Add a little contrast and other than the blade has to much light reflecting it looks pretty good.

I'll have to check that today. I thought maybe that might be it.
Thanks for the compliment!

I'm not sure what you mean by color cast. I don't have photoshop, but I do have microsoft Digital image 10. I know the basics,thats it.Maybe you can do this with my program. I'll give it a try.

OK. Went in and lessened the blue by subtracting the blue. That was in the yellow/blue spectrum.
Then auto contrast ( too bright) then brought ot down a couple of levels.
I'm really looking for a nice grayish/white backround.
I know all about clear glass and it does get a little lost but I really think it looks pretty good for an amateur.

You could try changing your background to something darker, like a dark grey. I think it would make the handle easier to see as well. I have had this same problem before. I use a gradient background and I just move my beads up to the darker end of the paper and that takes care of it.

Good idea. I'll have to order one.
Maybe I can put some black paper under the plastic.

Hi Kimberly
I don't mind the edit at all!
I think that you lost the silver detail with that edit.
For me...if something had to be lost,then I would give up the clear part in order to show the shiny metallic detail.
I do have picasa and was not able to accomplish much with that.
The second edit was Digital image10.
Maybe I should find someone on ESTY that could do it for me!

By color cast I mean that your background has a color to it and that color is reflecting onto your knife. If it was a neutral white then the light reflected off of it would be reflected would be white light.
You are going in the right direction with your edit you did but you lost contrast, so you need to increase that a bit to make up for it. There are a number of tweaks that can be done to improve an image, but it isn't a free lunch. Every change you make does something else that has to be tweaked for, which takes something else away. You might be able to fix one problem, but in the process create others that make the image un-useable. That's why it's so important to get the exposure, color balance, contrast, etc., as close as possible when you take the shot. Then if you have to do anything, it's enough to ehance the image but not take away from the quality.
I second the suggestion of getting at least Photoshop Elements, although what you have seems to do a good job at basic editing.
Mike

I would definitely recommend getting a gray or gradient background; I find that I get the truest colors and have to fuss about in Photoshop the least with a true-neutral gray background, although almost anything turquoise still throws my camera off.
A really great and fast way to color correct your photos is to set the gray point using your gray background, as long as your background is actually a neutral gray. A GREAT way to make sure your background is a neutral gray is to actually shoot your pieces on gradient paper or even gray card, which is quite inexpensive. It scratches and soils easily, though, so I suggest sandwiching it between two pieces of glass (you can have them cut to size at a hardware store, and use binder clips to hold them together... cheap, portable, and works like a charm).

I agree with Kalera. The true gray background results in the best colors and exposures for me.
I don't struggle with the turquoise, I do have a problem with red still. But at least with the gray background I have a chance at fixing it- on a white background I can never get it right.
I too would suggest checking your white balance setting if your heart is set on the white background.

On something that is completely transparent like the handle on this knife, you should use a a matte gray background. If you make the background white, which is easy to do, you stop being able to see the handle. It mostly disappears. The blade is fine, but the handle isn't visible.

hope you dont mind me playing edit too!
here is my edit - middle is with curves adjusted in the blue and green channels and sharpen, the last is full edit (would be better with a higher res image)
i never brighten because it never really looks good
also, invest in some really white colour temperature fluros - its the only way to photo silver - i've been doing jewellery for years (too long i think)

Look for "5000k" or "5100k" color temperature... I've seen them at Home Depot, and also you can order them online. Mine are 30 watt.

Well, it did not go as I hoped.
I think that I had better luck shooting outdoors.
Maybe my tent is too big.......24x24 and my lights are not bright enough.
I really was proud of the fact that I learned so much from all of the great tips in guiding me on how to set me camera settings,various backrounds,and WB settings.
THANK YOU SOOOOOOOOOO MUCH EVERYONE!
well here is the best from last night
next week I can take these skills and shoot outside!!

wow - much better!
you will find if you go outside that the colour temperature (the original blue problem) will be even harder to control - inside under lights will be more consistant.
i've found when i take a series of shots outside you can see the colour change in the photos as a cloud crosses the sun etc
i always take my photos a little on the dark side - its easy to lighten them up but really hard to fix overexposure
make sure you set your white balance every time
i used to have this nifty onscreen grey balance tool but i cant find it anywhere - you would photograph the 30% grey card and then use the tool to check the photo, it was great. I'll see if i can track it down for you.
and you always have the ultimate fallback tool - photoshop (my best friend)

i have a friend that actually works for Adobe - she gives me the new version every time it comes out, all i have to do is play with it for a couple of weeks and write a feedback report and i get it for free - gotta love those kind of friends!

If you need more light, try putting your lights inside the tent facing the walls and top. That way the light bounces around inside and not off the outside walls.
