It is my understanding that JPEG is limited to 8 bits, and that's what my website supports...Mike

p.s. IMHO, you DO NOT necessarily have to buy a better camera to take photos as good as mine. Experience behind the lens and in post processing will have more effect than the camera.

No it is 24 bits. GIFs are 8 bits and used to be that the net was limited to a dithered 8 bite palleted that I don't fully understand, but that is no longer the case. JPGs are lousey compression 24 byte images. You set it to 8 bit and then back to SRBG which I think is 24 bit bit format is not 32 bit.

Now with dimes, it is getting the focus that is the issue. Ignoring the problems with my camera's lens amd switch for the moment, it can focus on the dime, but the electronics wont do it. There is no override with focus.

This is as good as I can get, and that is with much suffering. I've used maganfying glasses to get details like you have. Your using a 200mm lens...hmm

It was my understanding that in most web viewers, 8 bit color from JPGs is the norm. Am I mistaken?

 

p.s. Also, PSE won't let me save my 24bit TIFF files as JPG unless I change to 8 bit. Are you sure you're not confusing JPG2000 and JPEG? Confusingly yours...Mike (who thought he understood bits, color spaces, and JPG compression before this conversation)

 

It used to be in the days of Mosiac that the browser limited color to 8 bit with the ability to define the pallet. I think it had to do with how graphic cards worked, especially with X11R6 where the desktop would reserve some pallet and the applications could have some other pallets. SGI workstations were a little more advances. And even until recently Windows ran in what was called Hicolor mode and also divided palettes.

I have no idea really why they did that, but todays browsers have no such limitation. Images in the browser now are as clear as the GIMP itself. In fact, the newest image standard in the Portable Network Graphic protocal (PNG) which you see me often use. it is a 32 bit layered standard that was designed to replace the GIF standard which had definite patent issues. But anything you read that says the Net is limited by a 8 bit color scheme is dead wrong. Firefox uses full color.

Abode is overrated...

just saying... although that suprises me.

I can load up about 5 graphic programs on this box and all will put JPG into 24 bit color (8 bit red, 8 but blue, eight 8it green) which comes out to 256 x 256 x 256 colors. Its been that way since the early 90's at least.

Its CMYK and Pantone which is a PIA.

We are saying the same thing, methinks. When I said 8 bit, I meant 8 bits per channel.

 

8bit dithered pallette GIF

-------------------------------



8 bit dithered web image in JPEG format (it is actually 24 bit or an 8 bit image)
----------------------------------------------------------------------



despite the name of the file this is a 24 bit PNG format - no lose image

---------------------------------------------------------------------



Dual Tone Imagine made with the Gimp just for fun in a PNG format

------------------------------------------------------------------------------------



full color jpg - as the camera creates but scaled down to size
-------------------------------------------------------------------------



another Dual Tone PNG file 24 bit color with 8 bit grey scale and 8 bit single color in a 24 bit format...

 

Ah - you confused me with this line

Because TIFFs are already 24 bit color. When scanners first started they created two competing formats... TIFF and JPEG. TIFF was better in that it was a lossless compression and storage algorithm but JPEG is small images with LOUSY compression (it removes part of the image) and both with 24 bit color.

At the same time Compuserve came up with the GIF graphic and presentation format which is much more than just graphic and can do presentations like Powerpoint, documentation with text and pictures, and animation, but it was only 8 bit color. And then the patent wars started.

I don;t know if that's the photo but you have some serious doubling on the noise ,mouth ,and the right portion of the bell i think it;s machine doubling ,but it's extreme/

Well here's a 1968 deep cameo silver proof augulla coin commerative president first day of independence 1968 coin to the left i would like some feed back on this coin look at the coin do you think the date is backwards and rhe july forth and the hole bottom portion of the obverse and reverse this is a mistake at the mint do you think? When i flip the coin over it's a 180 degress rotation. The second is a 79 proof ultra cam proof set.

No, jazzcoins - I am just a lousy photographer and the doubling you see are purely reflections.

 

Catbert and Leadfoot, GORGEOUS COINS!!! :thumb: :thumb: :thumb: And the pics are great too, very nice job guys. :thumb:

reflective coins can reflect their own details in the fields

Here are a couple of more 1874-1875.

 

Nice and older proofs...

very rare
