### 1. Choosing the right illumination
### 1. Choosing the right illumination
In the 'illumination' dropdown menu, you can choose the illumination that matches your hardware settings - meaning the selected SD & camera (W1 or X1, sCMOS or EM-CCD). Choose the laser line you need to excite your fluorophore (DAPI, GFP, mCherry & Cy5 - meaning 405, 488, 561 and 647 excitation lasers). The 'Quadband' illuminations have a filter that works for all wavelengths (so your recordings will be faster in case of multicolor imaging), however you will potentially experience more crosstalk, which you can check under https://www.fpbase.org/spectra/. If you are not sure, ask the facility for their help in figuring out whether you can use the Quadband. For each illumination (in case of multi-color imaging) go to 'Show live' adapt the following parameters to achieve the desired image quality (in that order):

For each illumination (in case of multi-color imaging) go to 'Show live' adapt the following parameters to achieve the desired image quality (in that order):
- the EMCCD Gain (only available for the EMCCD, a good starting value is 300), which only increases your signal on the detection side (no increase in photobleaching)

- the Exposure (if you have a mobile sample, you might save time by reducing the illumination time)

- the Laser power (be aware that higher laser powers and illumination times can result in irreversible photobleaching, which impairs e.g. brightness analysis). Do not use more than 10% of the laser power! If you are getting close to 10%, let the facility know and they will realign the lasers

When acquiring the brightfield channel, you only have to adapt the intensity of the Dialamp.
