Good flats?

Post by mgutierrez »

Hi all,

I would like to know your opinion about the following flats.

Taken with a tablet with an uniform and white background, covered with a stretched white shirt:

Same config, but without white shirt (directly with the tablet):

I don't know if both are ok, or wrong, or one is better than the other. To be honest, I don't notice many difference between them, even in the stacked result process.

Thanks for your help.

It's sort of hard to say whether a flat is "good". It is "good" if it adequately describes any uneven lighting happening in your imaging train.

Does the master flat correct uneven lighting correctly in your stacks?

Thanks for the reply Ivo. To be honest, I don't notice a big difference whichever combination I use. Maybe because I got only a few lights. I thought that a good/bad flat was easy to identify, but you're right, it makes sense. I will try again with a larger imaging session. Thanks!
