Bright Spot on my photos

[takemopics]

When I develop my B&W pics, I ALWAYS get a spot in the picture that is a little brighter than the rest of the picture....about the size of a silver dollar... what gives? Something goofy with my enlarger? Its a Beseler 23C. HELP ! !

Regardless of print size?

Regardless of print size?

yes,, i belive so,,,,

[Ian Grant]

It's an illumination problem, dirt or something, I don't know that enlarger make/light source but sometimes markings on a bulb cause that or dirt in/on a condenser or diffuser box. Sometimes bulbs are adjustable to improve illumination and prevent these problems.

That's not exactly a clear answer, but what the hell...

1) If the spot is there with different size, proportional to print size, then there's something wrong with the enlarger.

2) If the spot is there and has the same size, regardless of print size, it might be related to the easel. I'd look for a darker spot on the easel, having the same size with the spot.

Scenario 1 is the most obvious.

thank you for your comments,, sounds like you know what you are doing..... i will be trouble shooting tonight. Will you be online, if i have any follow up questions live ?

Tell us a bit more about the enlarger--what brand, model, and what kind of light source? This is a problem you might have, for instance, if you have a condenser enlarger that was missing one or more of the condenser lenses (sometimes there is only one unit, usually with two elements, but sometimes they can be separate and interchangeble).

I've moved this thread to the Enlarging forum and deleted the duplicate thread.

He said it's a Beseler 23C but he didn't say what head nor did he say if he's using VC filters nor did he say if the light area is very feathered or is more sharply defined. Could be a damaged filter or some other blockage. If it's a cold light head maybe something is on the lamp.

I dont know the answers regarding head, or VC filters...... I will be troubleshooting tonight 9pm eastern time, with my daughter who is studying photojournalism....... I will post ASAP,,,,, i need help ! and I appreciate your efforts!

The possibility of the wrong condenser arrangements spring to mind, or maybe just the condensors are not cranked to the right setting for the format he is projecting; they are adjustable for this enlarger. My 23 always had a frosted bulb; I don't know what might happen if a clear bulb was installed. Also make sure the bulb socket is fully seated on the enlarger head.

I have a 23C and had something like this after changing bulbs once. I then realized the new bulb had writing on it. I carefully scraped off the writing and everything was fine.
