Query re Photoshop CS4

[Quark]

Hi All,

I am seeking advice on a problem I seem to have inserting text with CS4, to be more precise, the size of the text.

After I have finished with my planetary RGB images in CS4 I annotate them, normally using 12 font text and this always works well.
These RGB images have been previously saved as TIF's after processing and combining in Astra Image Pro.

However, when I try and add text to my IR images, that have also been saved as TIF's, following processing in Astra Image Pro, I always run into the same problem in CS4. With the text font set at 12 the text that is actually produced is more like 36 font. This is very frustrating and I get around it by annotating my IR images in PSP V8.

Exactly the same thing happens with JPG versions of my images.

I have attached an RGB and IR from my most recent session Jan 23rd. If these images are loaded into Photoshop, with the text set at 12 font and you try to add text to them you will see my problem. On the RGB the text will be the size that you set it at but with the IR the text will be very large regardless of the font setting you set.

The answer to this pretty basic question is probably quite obvious, just not to me.

Any help would be most gratefully accepted.

Regards
Trevor

I have always found adding text to an image in photoshop painful to say the least. I am sure there is a painless way to do it but I am no photoshop expert.

My method is to take a copy of the area where I want the text and paste it into an old DOS/Windows 3.11 program called Picture Publisher, that came with an old scanner, as a new image. The text insertion tool in this program is the easiest I have found. Has a hundred or so fonts with virtually unlimited sizes, angles etc..

When I am happy with the result I copy it (Paste) back into photoshop then save in whatever format required.

I have attached a sample of what is possible. The first is a page scan (repaired) of a manual I have. The second is the same picture with different text added to synthesize a manual cover I was missing.

Trevor,

Are your RGB and IR images identical in resolution?

If not, what appears to be sized 12 font in one image, may actually be too big or too small in the other image.

Hi there H,
My RGB & IR images are all at the same focal length at 640 x 480 pixels. Just had a look in Photoshop and that is saying that the resolution of my RGB is 72 pixels/inch while the resolution of my IR is 300 pixels/inch, I do not understand how that can be.

I think it might be a lot less messing about to create a standard band with the image detail in that can be inserted across the bottom of the image.



Thanks Barry, I think I might have a go with your suggestion. When I have an imaging session it is generally 4 or 5 hours so obviously I capture a lot of data. The method I currently use to annotate the images really does take a lot of time at the stage when I am generally nearly asleep on my feet, (well backside).

Hi Trevor

The 72 dpi and 300dpi in the box shouldn't make any difference to to the text. It generally shows that a value for dpi was not actually specified and 72 dpi is usually the screen resolution.

As long as the size in pixels is the same you are OK. If you want to store it at 300dpi look at the picture size in pixels, change the value in the dpi window to 300 then re-enter the original pixel size in the size window and save. This will record the picture as 300 dpi. Really only important if you are going to print it out.

As I said before I am not an expert with photoshop but I have learnt a lot of tricks in it for re-generation damaged pictures like the ones in the sample I posted. The original page scanned for that picture was torn and had pieces missing out of it. It is over 70 years old and shows its age!

If you save your images in fits (fts) form your can enter all the data in the image header. This can be edited and read by many image programs.
