PS vs Maxim - Query on TIFF Images

[daz]

Below are two images of the moon from last night. Both are taken from the same RAW image from the 350D. I opened the RAW image in Canon's Digital Photo Professional and saved it as 16 bit TIFF. I then opened the TIFF in Photoshop and re-saved as a JPEG (for posting) and did the same in Maxim.

So, my question is why does Maxim white-out the TIFF image so much, whereas PS doesn't???

yea but , what process did u use Daz when in Maxim ????

[daz]

Nothing Rog. I just opened it and saved it. I did no processing at all.

I don't know about Maxim but Canons own Raw converter (left on auto) will read the image info file embedded in the original Raw file and adhere to that when converting to a Tiff. So, if the hi-lights were not blown at the time the picture is taken, the converted image will be fine.

Well, as I say, I used Canon DPP to convert from RAW to TIFF and loaded the TIFF into PS and Maxim - but with different results.

Oops! misread the question :?

I thought you were using Maxim as a Raw image converter...

If my memory serves well when saving files to certain cameras in certain modes the EXT info of the images are read differently by differant programmes?

[FLO]

James, Like me, you are probably thinking of the info saved with RAW files that is used by the RAW converter. Daz has already used the RAW converter to make a TIFF. He is wondering why that TIFF then looks different when opened in Photoshop and Maxim.

In truth, I am baffled

Could it be that these programmes have a set Historygram and when images loaded up into them they appear differently?

Strange one..
