Pro1 - Is it really...

sueanne · Apr 30, 2008

a black tulip?

This is what I saw in the shade
1/160s Digital Macro f/4.0 at 22.8mm AutoISO50 (forgot it was set at Auto ISO)

But in the sun, it looked more maroon.
1/400s Digital Macro f/4.0 at 22.8mm AutoISO50

I think it reminds me of plum color. What do you think?
Thanks for looking and c/c welcome.

I have seen ones that looked like that..not a true black,,but close,,,,You post pics that nice & still think you need a TZ 5,,,,I don,t think so....Thanks for shareing Ron

Hi Sue Anne,

Wow, quite a difference in different lighting situations!
It's definitely the darkest shade of red.
Great detail in these shots & the first especially with the look inside...

What's 'digital macro'?
Look's like 'auto ISO' was the right call... ;-)

Thank you Ron,

I myself wouldn't call it a black tulip but that's what is called.

A TZ5 is tempting only for the 28mm - 280mm zoom and compactness.
Will keep this on hold for the time being........

Thanks for looking and your comments.

Yes I think I would call it the dark red at the end of the color spectrum.

Shoot, I meant to say Super Macro (I was thinking SD series as Super Macro = Digital Macro)

Kota2k2 said:

Yes and I quickly put my ISO back to ISO50.

Thanks and have a good evening.

And you can have either picture look like the other. The differences you see are due to differences in white balance.

sueanne · May 1, 2008

Yes sbushman
next time I will try this in RAW.

I was in JPEG mode and converting this to RAW, the Pro1 can't do this in Super Macro. (But will try in RAW mode, Supermacro another time)

Actually besides WB, both views looked this color.
Just that a 'black' tulip really isn't black to me.

Thanks for the tip.

Hi Sueanne,

This is more likely UV/IR contamination.

Flowers' colors are always a challenge to get right.

Specially those that have colors that fall at both ends of the visible light spectrum namely Red and Violet.

Flowers, Plants and Birds' feathers have weird Ultraviolet and Infrared reflectance/absorption in order to attract their pollinators, birds and insects, that unlike humans can see a wider spectrum of light including UV/IR.

Digicams are sensitive to UV/IR so manufacturers put an optical UV/IR block filter so they can capture what we see, free from UV/IR contamination.

Is hard to balance the transmission of visible light with the blocking of both IR and UV light, so most cameras don't block UV/IR completely.

Most expensive DSLRs have Dichroic IR blocking filters so they can block more of it without affecting the visible light.

You can sort of fix it by adjusting the WB with the help of a WB reference card, but then the surroundings will shift colors as wells.

It would be interesting to see how your RebelXT render this same flower under the same light and using RAW.

I have not used these filters, but this is probably what you need if you want more color accuracy with those flowers.

or

If you buy one, let me know.
I'd be interested to see how it interacts with the Pro1.

Hello itt,

I had to reread this a few times before I could understand what you said.

Yes this is very true for the Pro1 as far as red and violets. (purples too)

Yes agree.

I am not sure I'll be back to take the 'black' crocus picture right away but I think with the 350D I can get truer colors correctly the first time than the Pro1 as far as certain flower colors.

BTW - it is called a 'black' crocus but in reality its not really black to me.

For example...
purple iris with the 350D and 50mm f1.4

Pro1

BTW - I did look at the filter links you provided, that sound like a good idea, but wish the filter didn't cost that much.
Unless I can leave that filter on all the time or just for flowers shots?

Thanks for your in depth insight, and have a great day itt.

Well almost all digicams have problems with those colors in some degree.

I have yet to see a true black flower or a person. =)
The only true black is the Black Beast with the red ring !!

Interesting, but a shot from the same angle and time could be more revealing.
The differences I see here are not big though.

sueanne said:

Yeah that is probably why manufacturers skip on quality filters.
I'd be interesting to replace the one on the camera with one of these.

sueanne said:

You could have it on all the time but....

It seems that some of these external filters have a blue cast when used at wide angles.
When these filters go on top of the sensor they don't have that problem.

Apparently you can use some of these external filters from 38mm (35Eqv) and on in the focal length to avoid the blue cast.
For that reason I wouldn't use it all the time.

The Fuji IS-1 is a finepix S9100 but with no internal UV/IR filter.
So to take normal photos you have to use a UV/IR filter all the time.

Here is a photo from a user and the B+W 486, notice the blue cast on the edges of the photo.

Very nice tulip pictures SueAnne. Our tulips have come & gone & really weren't as interesting as yours...they were red/orange & white. Right now our miniature roses are blooming.
Regards,
Don

sueanne · May 1, 2008

Thank you Don,

Well tulips do make for some pretty colors. I did see some white tulips with abit of red in them, but didn't get to shoot them. Sometimes I don't have the right camera with me.

Ah you are ahead with the roses, take pictures of them, I always enjoy the roses too. I think our roses will come in June.

Thanks for looking and have a nice evening.
(we'll be seeing rain in the next three days.....)
